Dispatched today if paid within 1 hr 21 mins See details. Venturi Size. Be careful pulling it out -- it's about an inch long. 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). 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 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. Useful experiment anyway. The main jet provides fuel from about 1500 rpm right up to maximum rpm. Or should I open what I have or rob from a newer model? Do you know what size high speed jet you have? With the richer 125Z air correction jet I got 11.8 km/l (27.9mpg) -- no real difference. Dave has done so with good success. 60 day return. Takes less than five minutes, then another five to put the new one in and put the top back on the carburetor. 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. (See the discussion of the air correction jet above.). Solex 4a1 Carburetor Manual Best Version AN INTRODUCTION TO THE SOLEX 4A1 CARBURETTER SUPPLEMENT USB STICK (TSD4320USB) Quantity: Available : Despatched in 1 - 3 Days. 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. Remove the brass plug with a hex head on the left of the carburetor -- bottom of the float bowl (all the fuel in the carburetor will rush out). If this is the case, try a larger size main jet -- size X127.5 1200/1300/1500cc engines. Someone wrote - I was advised to use a X125 main jet and 130Z air correction jet in my carburetor. The For 1600cc engines, use an X130 main jet. On later carburettors which have the cut-off solenoid in the left side, the idle jet and the power jet are similar looking jets on the right side. 2. Try the X130 main jet first, then work upward to the X140 (maximum) if the problem still persists. Many thanks, John!). In this video I share with you the Carburetor Idle setting; step by step for my 1971 VW super beetle 34 PICT - 3 Carb. Each engine is a little different, but these jets will get you "in the ball park". Just start off with a larger than normal size (150 maybe) and use the screw to increase/decrease the actual hole size. Solex Carb Spacer for Alternator, 30 PICT Carburetors, 00-3245- Carburetors intended for the California market were jetted leaner for emissions reasons and may be harder to tune as a result - so you might find a size X122.5 main jet and size 140Z-170Z air correction jets. This jet is critical to engine flexibility and economy. 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. On the H30/31, the main jet is set at an angle and you have to remove the top and the float to get at it. If the problem occurs at higher RPM (2500-4000), then you need to richen up your main jet. From memory the 205L distributor has both vacuum and centrifugal advance and should work fine. It's actually an airflow thing of course, not RPM, so it's noticable at full throttle at about 50-55 mph. Starts right up and runs great. Bentley (page 20 of the 'fuel' section -- table of 'carburetor setting and jets') says the X130 was normal for '71-'72 34PICTs, and X127.5 was normal for '73-'74s (non-California models). 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 idle jet is on the right side and the other jet there is a power jet (which only starts working at high throttle and high rpm). "Lean" means less fuel with the same amount of air, and of course "rich" is the opposite. Some of you may be using this Carburetor. Currently our response time to emails is slow (we are severely short-staffed). Carbs help Solex 32 34 Z2 Overclockers UK Forums. The power jet counters the leaner condition at higher rpms, richening the mixture back into balance again. Most carburetors come out of the box with a 55-60 idle jet. If the color of the deposit is tan or brown, you are running too lean and the main jet size should be increased. This valve closes when the key is off, preventing "Run on". You might want to drop a pilot jet size. Use a steady throttle - minimum acceleration. Normally, shops stock them in round sizes of "5"s, like 50, 55, 60, etc. 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. It's actually much easier to do if you remove the top of the carburetor and the float. Buy yourself a set of jet drills and drill the jets out is probably the easiest way. I played with the timing, the volume screw, almost everything, I even found a X120 main jet and tried that as well, but she's still failing. Pass the end of the accelerator cable through the cable pivot pin installed in the throttle lever. mains: 120, 130, 135, 145. air jets: 160, 170, 180, 185. Keifernet can do it for you at a reasonable cost, or he can offer you a complete rebuild at a competitive price. It appears to replace the plug in the bottom of the 30 PICT/1 carburetor float bowl, which has the jet mounted inside and in line with that hole. 3. Could you help me with the jetting? But engine sizes have much more variation, 1200cc to 1300cc is about 8% more, 1300cc to 1500cc is nearly 14% more, and 1500cc to 1600cc is about 7% more. This helped a lot. December 20th, 2019 - Peugeot 205 User Manual Solex 32 34 Z2 carburettors 28 4c Idle speed adjusting screw location 1 on the Weber 32 Located in: Braunschweig, Germany. Main jets are primarily from 2500-4500rpms, and Air jets affect the engine from 3500/4000 on up. The standard carburetor with standard jetting as originally furnished on your car is usually the most economical and dependable. Nomenclature There should be a light smooth coating of carbon on the rim of the threaded part, and a colour change on the outer electrode of grey (at the tip) to black (where it attaches to the rim of the threaded part), with the change of colour on the corner of the bend. Idle jets are available in small increments. The biggest problem I have with it was the fuel consumption. (Solex jets are marked with the hole size in mm, so a X127.5 jet has a 1.275mm hole - I'm not sure what numbering method Mikuni use). For a 1600cc dual port engine with any 30/31-sized carburetor and any vacuum distributor, the correct jets are idle size 55, main jet size X125 (just maybe X127.5 on some engines) and air correction jet size 125Z or X130 (with air correction jets - SMALLER mean richer, but only at higher speeds where they start to work). In most cases you can just leave the power jet alone. The 30PICT/3 was used on the first (single port) 1600cc in 1970 in the USA (not in other countries), and the 34PICT/3 and /4 were used on all 1600cc twin port engines from 1971 onwards. If you are using a 009 distributor with a 30PICT carburetor on a 1600 cc DP manifold, the main jet should be X130 or X132.5 and the air correction reduced to about 100Z. Milease has increased by 90 miles per tank. We disassemble the carburetor, and bore the venturi to 28mm for more air! This is what causes the visible rich condition, and confirms the need to increase the jet size. For example, the X130 main jet is a tad rich for the vacuum dizzy at sea level, so if the car is to be operated at a high altitude it will be running very rich, and you might get a smoother engine and less exhaust soot with an X127.5 or even an X125 main jet (the "right" size for 5000 feet altitude). The air correction jet starts leaning the mixture to bring it back into balance, but as the rpms (airflow) rises to near the maximum for that carburettor, the air correction jet works too well, running the engine lean. If it still seems hot, go to 127.5. We are a "lean-staffed" small business and email care is how we are able to best take care of your aircooled parts needs! Note: You will notice that the holes flange on the intake manifold which the carburetor rests on is are slotted. Adjustment directions are given below. Status: Offline. Note: The air correction jet size is very important when using a smaller carburetor on a larger engine (e.g., a 30PICT on a 1600cc DP engine). And the second issue is the presence of Ethanol (alcohol) in gasolines. MSRP Price: $9.11 You Save 12%. Air correction 75 to 125 and these are changed. The /4 version was used in California and had additional features to reduce emissions. The 137.5Z air correction jet is too big -- it's letting in too much air. You will find the Pilot Jet Valve in the same location as on the German 30 Pict-1 Carburetor. The three wires could each go up to fuse #12 individually, but that would be very inconvenient. When you work out the area of the hole in each jet, the steps are roughly 2% increase in fuel flow for each size up (X125 to X127.5 for example). Take the car for a run at a modest speed - say 35-40mph. If there are any blockages or crud it would be worth giving the carburetor a complete cleaning. A loss of power is the result -- about 58hp instead of 60hp. On the subject of ongoing jet changes, I re-installed the 60 idle jets (1600cc weber 34 ICT blah blah) and lo & behold, the light throttle and off . 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. If I can't iron it out with the high speed jet I'll start on the idle jet. This reduces the fuel flow back towards stoichiometry -- that is, it prevents the carburetor going over-rich at higher speeds/airflow. The air correction jet is also changeable. This carb is designed to remain compatible with SVDA distributors, and fits the stock air filter. Carburetor Cleaning Later versions of the Solex carburettor have the same body and thread as the idle jet close by, so don't confuse the two and interchange them or you will have a rich idle and lean top end. 2060 Solex Pierburg Kadron idle jet; 2056 Solex Air corrector jet; S61634017 Solex Z1 - Z2 Float; Solex float PBIC PIBC PICT; Solex float PICT; 6200018 Solex Needle valve size 160 Fiat 124, Alfa Giulia; 52844 Solex Pierburg needle valve VW PDSIT PICT DIDTA DIS; Here's the story: '68 bug with a ~'73 engine, 1600 dp, dual vac dizzy. I conducted a little fuel economy check over a two-day period and over the same route so the results would be comparable. The air correction jet has the emulsion tube attached to it -- this "foams" the fuel before it's added to the airstream in the throat. Make sure the old one you took out stays in good shape so it can be reused. If it has the small main jet, then you'll get better performance and easier tune-ups if you change it to a size X125 (for 1200/1300/1500cc engines) or a size X127.5 (for 1600cc engines) and change the idle jet to a size 55. 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. The fuel flow through each jet is determined by the airflow which creates a low pressure area near that jet. 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. We ONLY charge for items that are available to be shipped in a timely or reasonably reliable timeframe. The air correction jet prevents the mixture going over-rich at high rpm (again, smaller numbers means richer for this jet). Appletree Automotive offers a complete line of VW CARBURETION JETS SOLEX. We did a run of these, but due to a limited supply of the quality Bocar 34-3 carbs, we do not know how long we'll have these carburetors! . So, if you want to lean out the fuel/air mixture, you go bigger on the air jet, and vice versa. It provides fuel at low medium revs too, so if it's not working you'll get a rough idle and lean mix at lower revs. The 1600cc DP can flow more air than the 1600cc SP and smaller engines. Screw it in GENTLY until it bottoms. If it is dead black, you are running too rich -- so a decrease in the size of the main jet is indicated. I rebuilt the carb that was on it, as well as a. swap-meet spare, before installing the engine this spring. I have lowered the fuel pressure down to 2.5 psi and checked the float bowl fuel height. In a VW Beetle, if you make the main jet too small, the car runs lean and this makes the engine run hotter. That terminal on the coil is just a convenient place to obtain power to these components. Size 24 MB File Type PDF File Get free Mikuni Solex Service Manual Solex . So why worry about the jets? A sooty plug means the idle jet might be a little large. Orders are processed in the order that they are received and order fulfillment time varies. What you are mainly looking for is the condition of the carburetor. See details. Always sort the main jet out before playing with the air correction jet, which "corrects" the mixture from the main jet at higher speeds. DP case, 1641 P & C, w/ Scat C25 Cam, & stock heads. The old one for a pattern and a sharp hobby knife or box cutter works well. Except for the fact that it won't idle! PRODUCT IMAGES are representative only. The 30PICT/2 carburetor has a fuel idle cut-off in the right side of the carburetor but the 30PICT/3 and the H30/31 should have an air idle cut-off in the left side for the carburetor (same as the larger 34PICT/3) -- that was part of the change to the /3 carburetor version -- moving the idle cutoff valve to the left side. "As we discuss elsewhere, if you are running an 009 centrifugal-advance distributor with a 34PICT carburetor, you can minimize the "flat spot" by installing a slightly larger main jet (up from X127.5 to X130 or X132.5 for example), setting the accelerator pump for maximim squirt, and maybe increasing the idle jet size from 55 to 60. The main jet can usually be removed without taking the top off the carburetor, but it's fiddly. I would stick with the 34 pict 3 carb with the dual port. The jets in Dave's 34 PICT/3 carburetor are - Main jet - X130; Idle jet - 55; Air correction jet - 80Z ~~~ Jetting With the Centrifugal-Advance 009 Distributor, The 009 centrifugal-advance distributor can not sense throttle position engine load, only engine revolutions, so it's not ideal in all circumstances, Changing the jetting in . 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. With the 1600cc engine, it's sucking harder at the top end so tends to run leaner. Then video is intended as an example.. If the fuel/air mixture is too lean, the engine will run very hot, stumble, and misfire -- and burnt valves can be the result. With the larger main jet, you might also need to consider a size 50 idle jet in lieu of the normal 55. Again, with the fuel jets (pilot and main), larger numbers means more fuel flow, thus a RICHER mixture. I don't think you'd honestly notice the difference. The performance would tell you some of the answer, but inexperienced folks using one might get themselves into trouble where using a fixed (normal) jet and changing it for a larger or smaller one would give you a known change in fuel flow. Remove the main jet (as above) and blow through it (check for crud in the float bowl at the same time). by vwlover77 Fri May 05, 2017 6:58 pm. Carburetor body-to-cover gasket (6) But if you are using a cheater cam, or have a larger engine, this will likely work very well for you if you don't want the hassle of dual carbs! Accelerator pump diaphragm (24) the air correction jet is probably OK as either a 70 or 80 (remember, more displacement/larger carb, less correction needed). I also have a stock carb rack but it appears to have water damage and one or more carb is seized. We provide the classic VW hobby with tech tips, project advice, and quality parts for VW Restoration, VW Performance and Custom Aircooled VW projects. This is not correct. Our 74 Super has a tube running from the 34 PICT 3 down, and is . 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. Actual product may differ in appearance. 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. Great for that SLEEPER LOOK! For example, when used on a 1300cc engine with a vacuum distributor, the H30/31 should usually have a main jet of X122.5 and an air correction jet of about 140Z; but when used in a 1600cc single port engine, it should have a 125 main jet and a 125 or 130 air correction jet. SUPER-STOCK-34-3. To summarize: idle jets operate from idle to 2500-3000rpms or so. 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. Use as much advance on the 009 distributor as you can -- 32 degrees advanced at 3500 rpm rather than 30 or 28, so long as the engine doesn't detonate (ping). You can find 57s, etc. Solex 34 PICT 3 VW air cooled carburettor replacement; . Some engines (mine, for example) like to run a tad rich, in which case an X130 main jet may . Idle jet sizes of 70 or so will "run" on anything, but they don't run WELL (unless fouled plugs or 12mpg are your idea of "well"). All the plugs look the same -- black and fluffy, telling me a rich condition. This carburetor will NOT work well with cams with over 270 duration, (same as the stock 34-3 carb). Dave replaced the main, idle and air correction jets so he knew what he had. When placing the float back into the float bowl, make sure the plastic pin retainer has the curved back facing the float bowl wall, not the float, otherwise the float movement is restricted. None of these tests are definitive - just indicative. The air correction jet must be SMALLER to enrichen the mixture. 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. Contrast the Main Jet of the VW 105-1 for the '67 Beetle which would be120. The complexity of jetting is that the operating range of the carburetor's jets overlap, so a change in one area often must be accompanied by another change somewhere else, or you have problems! Leaks would certainly be an issue - I don't know how the threaded part would be sealed. But engines do differ a little, and the sizes above are "ball park" figures rather than definitive. The idle jet sits in a protrusion running down to the bottom of the carburettor, and the power jet sits in a protrusion running up to the top of the carburettor, so it's easy to tell which is which. Show Quoted Text . Unscrew the idle jet from the carburetor and the cut-off solenoid, and blow through it. If the idle RPM peaks at 2-3 1/2 turns out, you're OK. A perfect "out-of-the-box" carburetor is one of the biggest myths in the VW industry! The main jet is accessed by removing the big brass bolt on the left side of the PICT carburetor, right at the bottom of the carburetor bowl. I think the original idle jet was a 50, but the replacement jet orifices (orifii?) Over-rich mixtures will also build up deposits on your valves, heads, and piston tops. The proprietor of Aircooled.Net thinks the main jet is a size X130, and the idle jet is size 50.) I've rebuilt the carburettor, and it did not help. I remove the top of the carburetor, then run a thin screw driver (which avoids the coil) through the plug hole to get to the jet. $7.99 . While it is necessary to enrichen the fuel mixture when running an 009 distributor, you don't want the any richer than necessary since it will use more fuel. 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. I've been running my '68 Bug with the X127.5 main jet in the smaller carburetor, and he's running a tad rich. Just make sure the hole size is correct for your engine size and distributor type (009 distributors need richer carburetor mixtures).
