An altitude of 5000 feet is roughly equivalent to a one size main jet difference. The other one (pointing straight out to the right side of the car) is the power jet, which feeds additional fuel at high throttle/high rpm. This will have the main jet supplying the fuel, and read the plug again. The 137.5Z air correction jet is too big -- it's letting in too much air. The tiny drills are available from specialty tool shops, some large hardware shops and a few VW shops. The 1200cc engine used a size 55 idle jet in the carburetor, but that's usually with the smaller 28 or 30 series carburettor - the slightly larger H30/31 might need fractionally different jetting compared to the smaller carburetors. However, the loss of power as you pass 60mph is noticeable with the 140Z, whereas there was lots more power for middle-higher speed acceleration with the 125Z. Carburetor body-to-cover gasket (6) If you look at the two jets you can see that the (angled) idle jet sits in a protrusion (channel) which continues downwards under the jet, towards the idle and transfer ports in the throat near the butterfly. Then video is intended as an example.. Adjustment directions are given below. Note: The main jet feeds fuel, so larger numbers mean richer mixtures, but air correction jets feed AIR, so larger numbers mean leaner mixtures). 55 idle, 127.5 main. It this case you would definitely need to reduce the main jet size to say the size 122.5 or the 120. The fuel screw setting at idle trims the pilot fuel, and considering the fuel screw ends up at 1.5/1.75, the 1/8 throttle position (all 100% pilot flow) will be rich. To explain, the main jet supplies the fuel, and it supplies too much as the rpms increase (a function of the increasing vacuum in the main venturi). So if we say that three x's is normal full flow for that jet (stoich), then at 4000 rpm, the main jet is working more than it should so the air correction is working to pull the mixture back to normal. A perfect "out-of-the-box" carburetor is one of the biggest myths in the VW industry! Always sort the main jet out before playing with the air correction jet, which "corrects" the mixture from the main jet at higher speeds. Once again, try the conservative approach first, then get richer only if you have to. Check the jets in the carburettor - if you have a vacuum distributor (you didn't say which sort you had), then the 34PICT/3 carburetor should have a 55 idle (right side of the carburetor. The idle jet is normally a little larger when used with the heavy bodied Type 2 and Karmann Ghias - in a Bug you usually use a 55, for a Type 2 or Karmann Ghia use a 60 or 65this gives you a little more power at low and medium speeds. E10 usually needs a larger main jet and might also need a larger idle jet. So VW chose this configuration. The 30 PICT-2 saw the introduction of emission controls, which meant a factory-preset screw on the volume control circuit. The 1200cc engines usually used a X120 or X122.5 in the 28PICT carburetors, the 1300cc engines used either X122.5 or X125 in the 30PICT carburetors, the 1500cc engines usually used a X125, and the 1600cc engines usually need a X127.5 in either 30PICT, H30/31, or 34PICT, but MIGHT get away with an X125 in the smaller 30PICT and the H30/31. If it doesn't open you won't idle! Soot will indicate the main jet is a little too large. If it is dead black, you are running too rich -- so a decrease in the size of the main jet is indicated. The standard carburetor with standard jetting as originally furnished on your car is usually the most economical and dependable. Most carburetors come out of the box with a 55-60 idle jet. Both clearances are essential; If the accelerator pump linkage rubs on either end, the throttle lever will not be able to return all the way to the stepped cam, the result being an excessively high idle that cannot be controlled with the bypass screw. For a 1600 KG with 34PICT/3 and vacuum distributor, I'd suggest a 60 or 65 idle jet (a 55 idle jet is used for the bug but the heavy bodied KGs and buses used larger idle jets), 127.5 main, 80 or 100 air correction jet (80 makes it run a little richer in the mid range) and a 65 power jet. Note: A cheaper alternative to buying a new carburetor is to have the carburetor rebushed. It worked quite well, although the idle wasn't very accurate. Solex Carb Spacer for Alternator, 30 PICT Carburetors, 00-3245- Checking and adjusting cold idle speed =>page 22-53 Throttle valve positioner It is still UNCERTAIN, but we may re-open a substantially downsized version of our store again in the Spring of 2023. Note the three black wires leading from the positive terminal on the coil -- one to the backup lights, one to the automatic choke, and one to the idle cut-off jet. The larger size 65 idle jet helped the 30PICT/3 and H30/31 carburetors overcome the very lean main jet at idle and low speeds, and thus help to reduce the "bogging" problem. Solex 30 PICT-3, 34 PICT-3 and 34 PICT-4, remove the air bypass screw. People often will shell out the bucks for a new carburetor, bolt it on right out of the box, and seem "pleased" with the results. Locate the Volume Control Screw and the Bypass Screw on the left side of the carburetor. The air correction jet prevents the mixture going over-rich at high rpm (again, smaller numbers means richer for this jet). Another well respected and active VW carburettor rebuilder is TIM. Volume control screw O-ring (18) Note: Some people use a 13mm S-wrench (ring spanner) to remove the front nut. The air corrections I have are 125z, 170z and in the carburetor a 135z. . Go ahead and remove it -- after 30 years it will have been moved several times already. Change the main first and do a plug read as above. This means that the main jet is sized to the engine capacity, rather than the carburetor size, and X127.5 is the more common size for the 1600cc engine, rather than say the X125. But engines do differ a little, and the sizes above are "ball park" figures rather than definitive. A 44 IDF would need a 55 idle jet, and a 48 IDF would need a 60 idle jet. The smaller jets WILL NOT work with the 009 distributor. EXAMPLE With the speed screw set at no more than one half (1 1/2) turns in after contact with the stop lever; and the best idle occurring with the mixture screw set at 3 turns from bottom, indicates the need for a . It's a problem VW recognized very early on (since the aircooled engine has very hot heads and hot-spots were therefore more likely than in water cooled cars), so the fix was to add the cut-off solenoid to the carburetors. If you can't find one at about 125-130Z, try a smaller one, say 110Z. Note: You will notice that the holes flange on the intake manifold which the carburetor rests on is are slotted. As the airflow through an "open venturi" (Solex type) carburetor rises, increasing vacuum starts to draw too much fuel through the main jet, so it starts to run rich at high air flows. Classified ads, photos, shows, links, forums, and technical information for the Volkswagen automobile It's a complex problem that faces ALL open throat style carburettors. the size 65 power jet should work fine for those conditions. To compensate for this, an air correction jet is inserted in the fuel delivery circuit after the main jet, which starts to add air to the fuel emulsion as the airflow increases. On the H30/31 carburetor, there are two brass jets on the right side (right is right of car). If you don't have a compressor, talk to Santa Claus! Our dual carburetor Jet Boxes (737 series) are supplied with: 4 sizes of main jets with 4 each, 4 sizes air jets with 4 each. Another question - The car runs terrible but it runs. (See our Automatic Choke Discussion and Adjustment Procedure.). Note: You will be removing a number of small parts in this process; hopefully "stow them in a safe place" goes without saying. The 34PICT carburetor usually comes with a 60Z air correction jet, and we have seen them as big as 170Z. Peugeot 205 Manual . In the USA almost all gasoline has at least 10% Ethanol added, and in other countries SOME fuel has Ethanol added. As indicated previously, the VW engine actually runs better at fractionally rich settings (ideally 13.8:1 rather than 14.5:1 according to Bob Hoover who did lots of testing), but they are usually jetted a little leaner than that, so the X127.5 is really a minimum jetting for the 1600cc engine. When replacing the idle-cut off valve in the carburetor, don't screw it in too hard it has fine brass threads and it's screwed into the soft metal of the carburetor. [3] The Volume Control Screw is the smaller of the two adjusting screws. Pass the end of the accelerator cable through the cable pivot pin installed in the throttle lever. . It would be interesting to try using one an adjustable main jet, but there are some dangers too ? Aircooled.Net has them, and I think Gene Berg in the US has them too. Price: $ 399.95. December 20th, 2019 - Peugeot 205 User Manual Solex 32 34 Z2 carburettors 28 4c Idle speed adjusting screw location 1 on the Weber 32 The three wires could each go up to fuse #12 individually, but that would be very inconvenient. Once you have those two sorted, then try a faster run and from 60 try flooring the throttle - if you get a good smooth response the air correction jet should be OK, but if it tends to stumble a little or feel breathless, then either the main jet is a little small or the air correction jet is a little large. Try to use the leanest main jet you can -- too rich will only result in the cylinder oil film being diluted more, and this means higher cylinder wear. The 30 and H30/31 carburetors were designed primarily for the 1300-1600cc single port engines, but you can get slightly better performance with the larger carburetors on a 1200cc engine, but only if they are set to run properly with the smaller engine. to start at sea level. Brosol/Solex Idle Jets .40. Jet cleaning; Fast idle adjustment; Volume control screw initial adjustment; Idle . I haven't run enough through the tank to get a real idea about consumption yet, but since I don't notice any huge difference in performance I'll probably be going back to the X125 soon. This carburetor will NOT work well with cams with over 270 duration, (same as the stock 34-3 carb). 2 of 2 people found the following review helpful. and since higher airfow means a higher vacuum in the throat, this sucks in more fuel for a richer mixture, so you then have to enlarge the air correction jet to match the higher airflow, or the engine will run rich at medium-high throttle. Note: Compressed air is really best if you have it. Sounds like a good starting point! The power jet is needed to correct a tendency for the air correction jet to work TOO well at max airflow - it leans the mixture off too much and the power jet corrects this. Ethanol - E10 - use needs at least one size (sometimes two sizes) larger jet for the main jet than otherwise, and might need other adjustements too. . If you have a 009 (centrifugal advance) distributor, you may find that the spark plugs still seem a little dry/burnt looking at medium speeds , or the car lacks acceleration in the mid ranges. Have a look at the size stamped on it too. Located in: Braunschweig, Germany. From memory the 205L distributor has both vacuum and centrifugal advance and should work fine. Air correction 75 to 125 and these are changed. The X127.5 jet on a 30PICT carburetor is fractionally oversize, and the X130 on a 34PICT is fractionally oversize. You can email to cancel un-shipped/un-paid items at any time as long as they are not direct-shipped, special order or made/machined-to-order. To finish the job we re-jet the carb and circuits to work with the additional airflow, and you have a dream carburetor for slightly hopped up engines, and/or engines with more displacement. Rob provided further explanation: The idle circuit is behind the main jet - the fuel flows THROUGH the main jet to get to the idle circuit. Could you help me with the jetting? The extra advance helps reduce the 009 flat spot just a little. With the air correction jet you have to go 3-4 sizes different to see a real difference, unlike the main jet where one size can make a big difference. carburettor data 1124 cc models Venturi diameter 25 mm Main jet 127 5 Idle jet 48 Air correction jet 175 Emulsion tube EM Enrichment jet 50 . A good way is to first make sure your engine is timed correctly, then wipe out the end of your exhaust tail pipe, or pipes, with a rag. Rob responded - A X120 main jet would make it run leaner, and it sounds like it is too lean already. 55 idle is fine. Immediate shipment of requested products is NOT guaranteed. to the back of the engine, in an angle) is a: g f 50 and the other: g f 50. Great for that SLEEPER LOOK! general exploded view of the 34PICT/3 Carburetor is shown in the If your car is having a problem with spitting/sputtering/cracking, this is an indication of the fuel/air mixture being too LEAN. So I replaced it with a 30 PICT-3 carburetor in a good condition. Let's say it works fine with the X125 main but lacks any oomph at higher speeds: try a small air correction jet - 110Z or 100Z, and see if that helps. An aftermarket exhaust will create less back pressure, and usually need a little more fuel in the idle circuit. The emulsion tube mixes air from the air corrector jet with fuel from the main jet, and controls the mixture from the discharge nozzle at all engine speeds that the main jet is working. The old one for a pattern and a sharp hobby knife or box cutter works well. Rob's note: When removing the main jet, I use a small glass jar (pickle or baby-food jar) to catch the fuel from the brass plug - I hardly spilled a drop (I just allowed the plug to fall in to the jar), and used the fuel to refill the float bowl later. There is also a 65 power jet there too) a X127.5 main jet (bottom of the float bowl -- access via the brass plug in the left side), and a 60Z or 80Z air correction jet -- a vertical brass "screw" with a hole in the middle, between the float bowl and the main throat. The 30PICT/3 and the H30/31 carburetors came with size X112 main (super lean), size 65 idle, and size 125Z air correction jets, which made them very difficult to tune. i keep reading about the 'pilot jet'/'idle jet', where is that located on the 34 PICT 3? If this is the case, try a larger size main jet -- size X127.5 1200/1300/1500cc engines. Carburetor Disassembly I've seen a German jet kit for it but the main jet is 130 the idle is 65 the accelerator and emulsion are both 60. ANY SINGLE THING other than stock, Berg Semi-Hemi heads, 009 distributor, extractor exhaust, etc. Do not allow cleaning solvent to come in contact with skin. Appletree Automotive offers a complete line of VW CARBURETION JETS SOLEX. The center electrode should look quite clean and grey/white. such as, how do you know what mixture you are setting, and if you are running the car too lean and hot, or way too rich? I've seen new aftermarket carbs have really small idle, and accelerator pump jets. Take the car for a run at a modest speed - say 35-40mph. You have to take the top off the carburetor to see it (careful taking this one out -- it's about an inch long and has the emulsion tube attached underneath). The following topics are discussed in this article -. Sorry! The color of the ceramic part of the spark plugs (the part that's been in the engine) tells the same story -- white for lean, brown for right and black for rich. It should not need to be bigger than that with a vacuum distributor (009 distributors need richer mixtures). This gasket sets the fuel height in the float bowl; erratic behavior may result if the gasket is not correct. Please do NOT rely on PHOTOS while shopping as many of our products have selectable product options that may change the nature of the product being ordered compared to the representative photo. The valve on the Pierburg carburetor has a spring-loaded ball bearing on the end; it is likely that the valve in your kit does not. This jet is critical to engine flexibility and economy. Jetting With the Centrifugal-Advance (009) Distributor, Tuning the 009 Distributor/ Which one is which one? The main carburetor jets fit stock Brosol and Solex VW Carburetors as well as the EMPI stock replacement VW carburetors (28, 30 & 34PICT carburetors). Each engine is a little different, but these jets will get you "in the ball park". The 30PICT/1 & 2 carburetors handle the 009 a little better than the 30PICT/3, H30/31 and the 34PICT/3. We disassemble the carburetor, and bore the venturi to 28mm for more air! For example, a 40 IDF would need a 40 x 1.25 = 50 idle jet. 34 PICT Carburetor Combination. The power jet sticks straight out to the side, and sits in a protrusion nearer the top of the carburetor - if you remove that jet you can see a drilling straight through the carburetor body to the air correction jet/emulsion tube where the the main fuel supply is delivered into the throat of the carburetor. A sooty plug means the idle jet might be a little large. With a leaner 140Z air correction jet in the carburetor) I got 11.6 km/l (27.5mpg US). Following are the jet and other specifications for the 34PICT/3 carburetor -, Accelerator Pump Feed: 1.3 - 1.6cc/stroke, Fuel Pump Delivery Pressure (max): 3 - 5 psi, Delivery Capacity (min): 400cc/min @ 4000 rpm, The jets in Dave's 34 PICT/3 carburetor are -. So a 34PICT/3 carburetor with an 009 distributor should be jetted with an X130 or X132.5 main jet, and an 80-100Z air correction. Idle Shut Off Valve, 34-3, 34-4, and 34 PDSIT 2/3 Carburetors, 049-129-412C Is the valve on the side of the carburetor that provides air to the idle circuit. If it seems a little rich at higher speeds (plugs sooty after a plug read) then try the 130Z air correction jet. and jet > size. The selection of main gas and air correction jets is determined by venturi size. Dave jetted his new carburetor as follows: main jet - X130; idle jet - 55; air correction jet - 80Z. I've used this particular carburetor with a 1600cc dual port engine and it works fine with the same main jet, but seems to like a fractionally larger X130 air correction jet (it runs a little rich with the X125 air correction jet). To summarize: idle jets operate from idle to 2500-3000rpms or so. They might be available individually or in a set. I have lowered the fuel pressure down to 2.5 psi and checked the float bowl fuel height. Setting the idle screws (B): Tighten the screw until it touches the carburetor lever. Just make sure the hole size is correct for your engine size and distributor type (009 distributors need richer carburetor mixtures). So, I let it warm up, and set the timing to 32 degrees full advance. Thus a size 55 idle jet is 0.55mm, size 125 is 1.25mm, etc. Our site uses advanced code and encryption that is not supported by Microsoft's Internet Explorer Browser. A clean plug with a light grey/tan look means the mixture is about right. Please only continue if you are prepared to be PATIENT. Run about 100 miles and then look at the tail pipe. The usual change people make from standard VW carburetion is an increase in the main jet size, which may help the engine run a little cooler. You must do the opposite -- make the main jet a little bigger (X130 or X132.5) to stop the engine from hesitating when you accelerate. If your solex 34 pict 3 starts and runs fine when cold. Rob notes -- I have a 1500cc single port engine with it's original 30PICT/2 carburetor. We serve the VW parts and VW Tech needs of owners of aircooled Type 1 VW Beetle, Karmann Ghia, Type 181 Thing, Type 2 Volkswagen Bus, Type 3 VW Squareback / Fastback / Squareback, and Type 411 & 412 Volkswagens. can find them - rare!). any input would be much appreciated. But if you find a solid brass bolt, the main jet is further in the float chamber (later models) but still right in the back of it on the right-hand side. . Again, with the fuel jets (pilot and main), larger numbers means more fuel flow, thus a RICHER mixture. Air correction jets are harder to find. does anyone have a link to a graphic that explains where it is on the carb? Unscrew this bolt and look at it -- if there is a jet screwed into the bolt (older models), you can deal with it in hand, so to speak. May 13, 2014 @ 5:57 am. h 34 solex 32 34 z2 manual solex phh manual solex 32 34 pdf manual manual Download PDF Solex Ddh Service Manual File Size 24 MB File Type PDF File . Make sure your regular tuneup things are in order. The Pilot Jet Valve (idle jet) would be the g55. There is an pilot (idle) jet on all carburetors too - these are normally left at 55 for most carburetors (28, 30, H30/31 and 34 series), on any engine size (since it's only feeding the engine at small throttle settings anyway). The fuel flow through each jet is determined by the airflow which creates a low pressure area near that jet. The auxiliary (power) fuel jet is a small brass jet screwed into the right side of the carburettor, sittin in a protrusion running up to the top. It only works at full throttle and high RPMs ? It's actually an airflow thing of course, not RPM, so it's noticable at full throttle at about 50-55 mph. And the second issue is the presence of Ethanol (alcohol) in gasolines. Dispatched today if paid within 1 hr 21 mins See details. . If I can't iron it out with the high speed jet I'll start on the idle jet. Size 24 MB File Type PDF File Get free Mikuni Solex Service Manual Solex . If the color of the deposit is tan or brown, you are running too lean and the main jet size should be increased. 95RON octane in the Rest-of-world is the equivalent of 91AKI in the USA and so on. Here's the story: '68 bug with a ~'73 engine, 1600 dp, dual vac dizzy. There is a Mexican Solex 30 Pict-1 replacement Carburetor. The standard jetting that the 30PICT/1 & 2 carburetors came with is size X122.5 or X125 main, size 55 idle, and size 125Z air correction jets. There are three (or four) removable jets. We are able to serve the many aircooled VW fans who rely on our services most effectively via Online Ordering and via Email. Others might find that the 30 sized carburetor on a 1600cc engine works better with a larger X127.5 main jet. Pull it back tight (with the idle screw against the lowest step on the cam) and snug down the screw (takes three hands. Home . Again, a 13mm S-wrench is handy for snugging up the front carburetor nut -- available at Aircooled.Net. SOLEX 34 PICT 3 Carburetor Adjustment Procedures. Solex 34 PICT 3 VW air cooled carburettor replacement; . You may have to get creative about how you attach so many wires to the single terminal on the coil. There is enough variation in fuel types, wear and tear on engine and carburetor, altitude and so on that you might need to experiment a little. (The jets are made in 2.5 increments, so it goes X127.5, X130, X132.5, X135 etc. The biggest problem I have with it was the fuel consumption. If the engine is stumbling at 2000 RPMs and lower, then you need to richen up your idle jet (go to a larger size) - but check carefully for air leaks around the throttle shaft first!. Just start off with a larger than normal size (150 maybe) and use the screw to increase/decrease the actual hole size. Location: Miami. Same with the carburetors in general, so adjustments become essential. PRODUCT AVAILABILITY can vary and short-term backorders are common. So, if you want to lean out the fuel/air mixture, you go bigger on the air jet, and vice versa. Lightly lubricate the choke valve shaft and throttle valve shaft with engine oil and the external linkage with molybdenum grease. and 34-3 carb. Another - You mentioned a bigger jet -- are they available? No blue fumes, so the piston rings are well installed. JET KITS are available if needed. Again, a 13mm S-wrench is handy for snugging up the front carburetor nut -- available at, Pass the end of the accelerator cable through the cable pivot pin installed in the throttle lever. These carburetors come jetted "generally", and will bolt on and run. If the idle cut-off valve fails in the shut position, the car will still run (roughly) on the main jets but will stall as soon as you take your foot off the throttle. I couldn't find it in any book. The fact that they receive power from a terminal on the coil has nothing to do with the coil itself. Also make sure the accelerator pump is set for full squirt, and is squirting straight down the throat past the opening throttle plate - not splashing on anything on the way. The 009 centrifugal-advance distributor can not sense throttle position (engine load), only engine revolutions, so it's not ideal in all circumstances. The power jet counters the leaner condition at higher rpms, richening the mixture back into balance again. Actual product may differ in appearance. The idle cut-off valve receives power from the positive (+) terminal on the coil (#15) -- see the schematic which shows this wiring arrangement. 60 day return. Then if you need a fatter idle go up to 57.5, then 60. Sent from my SM-G930F using Tapatalk This is so you can move the carburetor back and forth a bit (front-to-back) to assure that the accelerator pump linkage on the right side of the careburetor clears both the fan shroud at the front and the alternator body at the back. The Power Fuel System Dispensing Nozzle for the VW 105-1 would be 0.50 with no check ball. If it still seems hot, go to 127.5. Dave bought a Pierburg model 34PICT/3 carburetor from Aircooled.Net, and none of the jets had the sizes stamped on them. Recommended sizes are given in this article. Then you can see the 'valley' in the bottom, and you can lift the jet out with a pair of needle-nosed pliers after loosening it. Main jets are primarily from 2500-4500rpms, and Air jets affect the engine from 3500/4000 on up. Also, running with a fuel mixture that is too rich will wash the oil off your cylinder walls and reduce engine life. You can also get detonation (pinging/knocking) if the engine gets too hot. Details. (You must log in or sign up to reply here. These plates provide restriction and also atomize the fuel/air mix better for greater fuel economy. Using a new gasket, install the carburetor on the intake manifold flange. Be careful that you don't tighten these nuts too much -- you may strip the stud out of the base of the carburetor. With the idle cut-off valve working correctly, hot spots in the cylinders don't occur as readily, since there is no fuel available to keep the engine running once you turn off the ignition. The try the same test at a higher speed - a steady 55-60mph. Float needle valve and gasket (4 & 5) (See note below.) Make sure this fits by entering your model number. With lean jetting you are likely to need more throttle and have slightly worse fuel economy - using the slightly richer settings I'd suggested above will give you a little more power and a cooler running engine, so hopefully fuel economy will improve a little, but don't expect too much - fuel economy with the heavy Type 2 body is never very good. Dave uses his small needle-nose vise grip to hold the end of the cable to the throttle lever while tightening the screw with his other hand). Note: Compare the new float valve with the old one. As we learn more, we will include it here. Following that is a listing of the parts, giving Dave replaced the main, idle and air correction jets so he knew what he had. Ethanol contains USED oxygen which canoot be burnt again, so adding ethanol to gasoline/petrol, reduces the amount of energy per litre/gallon. In addition, if you have a problem with a 55/60 idle jet, and you have the right main jet, and still have a hesitation regardless of accelerator pump adjustment, you need to play with your idle air bleed (what the fuel from the idle jet mixes with). All Solex carburetors tend to run lean at high power settings (high rpm and open throttle). if you look around to really get it right on! Reply to Phatman. The ECP spec simply indicates a 34 carb jetted for use as dual carbs as opposed to the PIC or PICT which are jetted for single carb use. Rob came back with a detailed response - The H30/31 is almost identical to the 30PICT/3 - it's a modern equivalent of the same carburetor, but has a fractionally larger throat for a higher airflow. Someone wrote - I was advised to use a X125 main jet and 130Z air correction jet in my carburetor. If you have a 009 distributor (no vacuum canister on the side), the main jet should be about X130 or X132.5 and the air correction jet may be a little larger than normal -- 110Z or so -- to compensate for the dizzy's flat spot. Be sure to check your engine's fuel pressure and ignition system. All this indicates a good mixture and correct heat range.
