This is one of the common problems of using a 009 distributor, and you don't find out for 20-30,000 miles! The try the same test at a higher speed - a steady 55-60mph. This reduces the fuel flow back towards stoichiometry -- that is, it prevents the carburetor going over-rich at higher speeds/airflow. But after November 15th, all still pending backordered unshipped items will be automatically CANCELLED **(except for any special ordered drop-shipped or made/machined-to-order items). The air correction jet prevents the mixture going over-rich at high rpm (again, smaller numbers means richer for this jet). 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. 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. Then tighten further according to the chart. vegas the 127.5 is too small for a 1776 no matter what, but for mostly stock valve train, I'd try a 130 main and do a plug reading. valve - idle cut off (30pict-2,3) 5. plastic cap 26. plug - av x. fuel jet 6. spring - throttle return 27. 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. Then if you need a fatter idle go up to 57.5, then 60. 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. Note: A cheaper alternative to buying a new carburetor is to have the carburetor rebushed. 3. I find it much easier to just use a regular 13mm box-end wrench (ring sopanner), as getting the S-wrench on and off of the nut is very difficult (walls on the box (ring) end are too thick). Note: It is very important that you install the correct needle seat gasket. Air is much less dense than gasoline, so that makes sense. It's possible to develop partial blockage in one or more jets. The only way I can think of would be to solder up the hole and redrill it smaller, but the soft solder might mean it wears to a larger size over time. Super Stock 34 PICT 3 (34-3) Carburetor, LIMITED PRODUCTION, 12V, Bocar. 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 . Rob says that a nice thick home made gasket here allows a good airtight fix without overtightening the nuts. You might want to drop a pilot jet size. For a 1776cc engine with 009 distributor, 55 idle, X132.5 or X135 main, and air correct around 80Z should be close to the mark. Turn the Bypass Screw (the larger one) out a couple of turns, to get things started. 55 idle is fine. 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. Carburetor body-to-cover gasket (6) Because the aircooled engine runs hot anyway, the smaller jet in the carburettor can result in too much heat and burn the exhaust valves. Status: Offline. 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. We need to do some research regarding the adjustable main jet. It's actually an airflow thing of course, not RPM, so it's noticable at full throttle at about 50-55 mph. The main jet provides fuel from about 1500 rpm right up to maximum rpm. The Pilot Jet Valve (idle jet) would be the g55. The smaller jets WILL NOT work with the 009 distributor. The numbers are: 231 168 015, and 043 905 205 L in the second line. It's important that you get it right. The 1600cc DP can flow more air than the 1600cc SP and smaller engines. Every engine is different, so strongly consider getting our micro sized idle jets to really dial it in. If it takes 4 1/2 to 6 turns to peak, go up a size or (1/2 size if you. December 20th, 2019 - Peugeot 205 User Manual Solex 32 34 Z2 carburettors 28 4c Idle speed adjusting screw location 1 on the Weber 32 (See the discussion of the air correction jet above.). It is very easy to check the idle cut-off valve to make sure it is functioning properly. I have lowered the fuel pressure down to 2.5 psi and checked the float bowl fuel height. It evolved from the 28 PICT which became the 30 PICT in 1968. Make sure this fits by entering your model number. Jet-A-Vator. If it doesn't open you won't idle! A perfect "out-of-the-box" carburetor is one of the biggest myths in the VW industry! All information should be verified prior to use. Regarding the 1776cc engine: the stock 34PICT/3 carburetor with a fractionally larger main jet and a fractionally smaller air correction jet to suit the higher air flow being asked of the carburetor should suit nicely. The power jet is usually a size 65. Idle jets are available in small increments. In most cases we are able to honor advertised price, but in the RARE case a substantial price increase occurs, you would be notified and given the option to cancel. All this indicates a good mixture and correct heat range. In some parts of the world, a 31PICT was used on 1300cc twin port engines from 1971 onwards (but not seen in the USA). On the /3 and /4 carburetors - it looks like a bolt with a tiny silver plug in the center. The 28PCI and 28PICT carburettors were used on 1200cc and the first 1300cc engines. The power jet only works at higher throttle positions and higher rpms. Rob's note regarding modern fuels: There are two major issues with modern fuels. 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. On the twin port engines, it has to be used with a 30/34 adaptor, since the twin port manifold has a larger mounting flange than the single port manifold. "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. 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. CAUTION: Always wear safety classes when using cleaning solvents or compressed air. Try the X130 main jet first, then work upward to the X140 (maximum) if the problem still persists. Check the float valve for binding and leakage. On a 1600cc the main jet should be a size 127.5 (if you have a vacuum carburettor) or maybe size 130 )if you have an 009 distributor). 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. Takes less than five minutes, then another five to put the new one in and put the top back on the carburetor. ; Replace Part Number: 98-1289-B, 113129031K.Dual Port Manifold only, Not for single port. 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. We have heard it said that the X130 (or X127.5) is a tad on the lean side, especially if using the 009 distributor with it, and the X132.5 gives a fractionally rich mix (which VWs have always liked better than lean). The angled one (points slightly towards the rear of the car) is the idle jet. I've never had to do this so don't even know if it would work well. 55 idle, 127.5 main. Try the X125 main before you try the X127.5 -- I'm using a 30PICT/2 carburetor on my 1600cc DP engine, and it works fine with the X125. 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. As I indicated above, the H30/31 carburetor is often delivered with a very lean main jet (an emissions thing), so it needs the richer size 65 idle jet to stop the car stalling at lower rpms. Discussion in 'Mech Tech' started by low_light_craig, Jun 9, 2017. low_light_craig. Rob replaced the air correction jet with a 140Z, and at low-middle speeds there is no discernible effect. A loss of power is the result -- about 58hp instead of 60hp. 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. 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. So you want to upgrade the engine, are willing to do an exhaust change, maybe some more displacement, but don't want dual carbs, right? Milease has increased by 90 miles per tank. An altitude of 5000 feet is roughly equivalent to a one size main jet difference. This jet is critical to engine flexibility and economy. A 44 IDF would need a 55 idle jet, and a 48 IDF would need a 60 idle jet. 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). Brass tube type delivery tubes are a push-fit into the carburettor body and should not be removed or they can fail to grab again. In the boxes of parts was a new manifold for the 34 Pict 3 carb. I managed only 22 mpg on a highway (around 50-55 mph), and 19 mpg when I was driving around 60-65 mph.

When using the 30PICT or H30/31 carburetor on a twin port manifold and any vacuum distributor, change the jets to X125 or X127.5 main, 55 idle, and leave the air correction . You can find 57s, etc. to start at sea level. If the color of the deposit is tan or brown, you are running too lean and the main jet size should be increased. If the valve sticks in the open position, the idle fuel circuit will remain open, so if the engine is still turning it will still draw fuel through the idle jet, resulting in running on if there is a hot spot in one or more cylinders. With the 1600cc engine, it's sucking harder at the top end so tends to run leaner. Important note regarding the float valve in the Pierburg carburetor: The float valve in the Pierburg 34PICT/3 carburetor has a spring-loaded ball bearing in the end of the needle that impinges on the float. 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. Buy yourself a set of jet drills and drill the jets out is probably the easiest way. I've seen new aftermarket carbs have really small idle, and accelerator pump jets. I think the original idle jet was a 50, but the replacement jet orifices (orifii?) Now I have installed a newer Solex Brosol 30/31 carburetor (the Brazilian one), in good shape. Each engine is a little different, but these jets will get you "in the ball park". You'd think the jet sizes would follow the capacity more closely, but they don't. The exhaust system peashooters started turning black inside as soon as I put the larger jet in. 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. With the larger main jet, you might also need to consider a size 50 idle jet in lieu of the normal 55. following topics related to the 30 PICT/2 and 3 and 34 PICT/3 and 4 The last three carburetors are more sensitive, and so the lack of vacuum advance on the 009 makes more of an impact. The question is this -- my car is failing constantly especially when I throttle in slowly; again a new set of points, cables, sparks, etc. Note: Do not soak the choke heating element, pump diaphragm, float, vacuum diaphragm, or any other rubber or plastic parts in carburetor solvent. Jun 10, 2013 (Edited) cactu4r said: I've got a recently rebuilt 1600 DP, 34-pict-3, DVDA, and I am having the hardest time getting the engine to idle. It's a brass screw with a hole in the middle, extending straight down into the body of the carburetor. Delivery: Estimated between Mon, 6 Mar and Wed, 15 Mar to 23917. 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. 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). Any auto supply store can sell you a little T-shaped adaptor that will fit on the terminal, with three "wings" (if you will) to which the three black wires can be attached. Perform the Idle Adjustment and Timing procedures. If it is any lower the choke may be staying on too long, or it may be stuck on and won't open at all. Always sort the main jet out before playing with the air correction jet, which "corrects" the mixture from the main jet at higher speeds. The most common power jet size on all Solex carburettor versions is 65 (except for the H30/31 which usually has a smaller power jet - around 47.5). If your car is having a problem with spitting/sputtering/cracking, this is an indication of the fuel/air mixture being too LEAN. 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). 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. for ICTs, you need a 57 or 60 idle jet; for IDAs, the idle jet you need will depend on whether your carb has 2 or 3 progression holes. 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. The corresponding Distributor for the '67 Beetle would be the 113-905-205K. 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. PRODUCT INFORMATION: All information provided by Aircooled.Net (via website or email) is for USE AT YOUR OWN RISK. Change the main first and do a plug read as above. Sent from my SM-G930F using Tapatalk If your solex 34 pict 3 starts and runs fine when cold. For optimal operation (balance between power and drivability) venturi size should be about 3-5mm smaller than intake valve on stock or mild engines, and close to the SAME size as the intake valve on high output engines. Automatic These plates provide restriction and also atomize the fuel/air mix better for greater fuel economy. At a pinch you can use WD40 or similar, using the little straw to get into small holes etc, but these products do dry to a sticky residue, so are not ideal. EMPI Performance Products Pict-3 34 Direct replacement for the original Solex 34PICT3 - comes with 70 Air Jet - 127.5 Main Jet - 55 Idle Jet SO-100 $ 28.62 Solex Pict-3 28/30/31/34 Rebuild kit G1134 $ 3.25 Gasket - Flange Gasket - ID 1.540 98-1288-B $ 189.95 . Note: Compare the new float valve with the old one. The air corrections I have are 125z, 170z and in the carburetor a 135z. PRODUCT AVAILABILITY can vary and short-term backorders are common. Once all together, retune the carbs (mixture and idle speeds) as per standard VW tuning methods. Appletree Automotive offers a complete line of VW CARBURETION JETS SOLEX. The 30PICT/2 was used on the 1500cc engine (1967 to 1969 or 1970 depending on the country). So how do you know which to use? As we learn more, we will include it here. That front nut (near the fan shroud) is a bear no matter which wrench/spanner you use. Be careful pulling it out -- it's about an inch long. Note: Some people use a 13mm S-wrench (ring spanner) to remove the front nut. 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. 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. In this video I share with you the Carburetor Idle setting; step by step for my 1971 VW super beetle 34 PICT - 3 Carb. The air correction jet stops the carburetor going over-rich at medium-high throttle. 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. Here's the story: '68 bug with a ~'73 engine, 1600 dp, dual vac dizzy. You also set the accelerator pump for maximum stroke when using the 009. [3] The Volume Control Screw is the smaller of the two adjusting screws. Pilot jet cutoff valve: 3: Carburetor upper half: 15: Gasket: 27: Circlip: 4: Float needle valve: 16: 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). SUPER-STOCK-34-3. That's how I got mine! 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). 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. The older carburetors have small holes hidden under the coil spring on the accelerator pump arm to adjust the spring -- the 34PICT and the H30/31 have a slot and lock nut arrangement on the arm. When using the 30PICT or H30/31 carburetor on a twin port manifold and any vacuum distributor, change the jets to X125 or X127.5 main, 55 idle, and leave the air correction at 125Z. If you live at altitudes above 5000 feet, you also have to consider that, as high altitude results in the engine running rich (less oxygen in the air but the same fuel flow through the carburetor). 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. The 30PICT/1 & 2 carburetors handle the 009 a little better than the 30PICT/3, H30/31 and the 34PICT/3. Secure the fuel hose to the inlet nozzle on the carburetor with a new hose clamp. 34 PICT-3 carb, SOLEX 34MM ; Fitment: Carburetor Fits For any 1600cc VW Air cooled Type 1 engines,such as: 1971-1979 Volkswagen Beetle, 1971-1979 Volkswagen Super Beetle, 1973-1974 Volkswagen Thing, 1971-1974 Volkswagen Karmann Ghia, 1967-1973 Volkswagen . This carburetor will NOT work well with cams with over 270 duration, (same as the stock 34-3 carb). On the H303/1 it is often oversized too - a 65, used to stop the engine stalling at low rpm as the main jet supplied with these is often VERY lean 117.5 or 120. 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 is also changeable. But different gears and different rpm doesn't. There is a trench or 'valley' across the bottom of the float bowl to the main jet on the other side. Setting the idle screws (B): Tighten the screw until it touches the carburetor lever. The If you do not hear this clicking sound, it's time to replace the idle cut-off valve. Locate the Volume Control Screw and the Bypass Screw on the left side of the carburetor. Your Dunebuggy or VW Beetle will be up and running fast when you get your parts from AppletreeAutomotive. 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. ANY SINGLE THING other than stock, Berg Semi-Hemi heads, 009 distributor, extractor exhaust, etc. (Some of this material was adapted from John Connolly's article on How to Jet Your Carburetor.). 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. And the second issue is the presence of Ethanol (alcohol) in gasolines. Others are upset by a backfiring, or smoke belching monster. The VW 105-1 Air Correction Jet would be 125z. Air correction 75 to 125 and these are changed. Useful experiment anyway. Air correction jets are harder to find. The timing is set ATDC. This valve closes when the key is off, preventing "Run on". Some of you may be using this Carburetor. 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. Do you know what size high speed jet you have? If it's working, you'll hear a clicking sound as the relay pulls in. Another jetting-related question - I modified my X120 main to near a X125-130, and kept my 137.5Z air correction jets. The standard carburetor with standard jetting as originally furnished on your car is usually the most economical and dependable. Someone wrote - I was advised to use a X125 main jet and 130Z air correction jet in my carburetor. You can also get detonation (pinging/knocking) if the engine gets too hot. Free shipping for many products! "Lean" means less fuel with the same amount of air, and of course "rich" is the opposite. If I can't iron it out with the high speed jet I'll start on the idle jet. Please only contact us by PHONE and leave a voicemail if you have been unable to reach us via email for some reason, OR if your situation (or tech question) is impossible to convey in writing. I've been running my '68 Bug with the X127.5 main jet in the smaller carburetor, and he's running a tad rich. Carburetor Removal The 137.5Z air correction jet is too big -- it's letting in too much air. Replacing the main jet in is super easy -- just put it in the hole in the side of the carburetor, then put the screw driver in after it and slide it along the 'valley' that runs across the bottom of the float bowl. The sizes are stamped in tiny numbers on the heads of each jet. carburetors are discussed on this page -, General Exploded View Remember on the 34PICT-3 the idle jet affects drivability and power up to about 2,000 rpm when the main jet takes over. Use stock vacuum line from air-intake #4 for CDI control unit. This is what causes the visible rich condition, and confirms the need to increase the jet size. The extra advance helps reduce the 009 flat spot just a little. So, I let it warm up, and set the timing to 32 degrees full advance.
