I'd avoid Chinese stuff on eBay. Delivery: Estimated between Mon, 6 Mar and Wed, 15 Mar to 23917. (See the discussion of the air correction jet above.). Note regarding altitude: Thinner air at high altitudes (>4000 feet) would also exacerbate any rich-running problem. The 137.5Z air correction jet is too big -- it's letting in too much air. 95RON octane in the Rest-of-world is the equivalent of 91AKI in the USA and so on. 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. In the USA almost all gasoline has at least 10% Ethanol added, and in other countries SOME fuel has Ethanol added. Classified ads, photos, shows, links, forums, and technical information for the Volkswagen automobile 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 -. 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 if you need a fatter idle go up to 57.5, then 60. 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. Most gasoline in the USA now has at least 10% Ethanol added (E10), and in other countries, SOME fuel grades have 10% ethanol added. I think the original idle jet was a 50, but the replacement jet orifices (orifii?) FreeShipping. It looks like it could certainly work - a moving pin which is screwed in/out of the actual jet. Single 40/44/45mm carburetor, venturi range 28-32mm, Typical displacement of up to 1900cc. following topics related to the 30 PICT/2 and 3 and 34 PICT/3 and 4 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. were visibly larger in the new jets than the old ones. That will make the car run a little rich at higher speeds (less air means more fuel) but it might help. Pass the end of the accelerator cable through the cable pivot pin installed in the throttle lever. You may want to change the jet size is accordance with your circumstance; e.g., smaller jet size at high altitude (X125 at 4000 ft.). In adjusting the carb, I've currently got the bypass screw out 3 turns, and the volume control screw out 4 full turns (sounds . If it's not, the float bowl will overfill through the bowl vent down the throat of the carburetor, causing the fuel/air mixture to be WAY too rich - and of course the exhaust will spew out a lot of black smoke and the engine will not run. It this case you would definitely need to reduce the main jet size to say the size 122.5 or the 120. So VW chose this configuration.

Product Description. 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. Regarding fuel consumption as a function of jet size -- The 1600cc Beetle should get about 10-12km/l (24-28mpg). mains: 120, 130, 135, 145. air jets: 160, 170, 180, 185. . Change the main first and do a plug read as above. *** Supply-chain disruptions have hampered our ability to acquire/restock items reliably, and a lack of backorder ETA information is the frustrating "new normal" for our hobby. . 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). The only method of getting it exact is to run the car on a dynomometer with an exhaust gas analyser in the exhaust pipe. I also have a stock carb rack but it appears to have water damage and one or more carb is seized. Dave has done so with good success. . jet - aux idle speed fuel 4. cover -with spring and heater element 25a. Check the float valve for binding and leakage.

Most carburetors come out of the box with a 55-60 idle jet. These plates provide restriction and also atomize the fuel/air mix better for greater fuel economy. Every engine is different, so strongly consider getting our micro sized idle jets to really dial it in. Once again, try the conservative approach first, then get richer only if you have to. The 205L number is a Bosch number, the other one is a VW number. Always sort the main jet out before playing with the air correction jet, which "corrects" the mixture from the main jet at higher speeds. vegas These are setup for 12V electrics, and include the idle shut off valve. Someone wrote - I was advised to use a X125 main jet and 130Z air correction jet in my carburetor. See our Accelerator Cable Adjustment Procedure. So I replaced it with a 30 PICT-3 carburetor in a good condition. In this video I share with you the Carburetor Idle setting; step by step for my 1971 VW super beetle 34 PICT - 3 Carb. Air correction jets are harder to find. (The jets are made in 2.5 increments, so it goes X127.5, X130, X132.5, X135 etc. Currently our response time to emails is slow (we are severely short-staffed). Hey, use the stock jet size, which is 125 for the 34 PICT-3. The old one for a pattern and a sharp hobby knife or box cutter works well. Jetting was tweaked over the years for various carbs and territories. 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. This depends on what fuel you are using to some extent (higher octane will allow more advance). The adjustable jet would work with any of the Solex carburetors which have the jet mounted horizontally inside the carburetor. SOLEX 34 PICT 3 Carburetor Adjustment Procedures. 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. 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 larger main jet, you might also need to consider a size 50 idle jet in lieu of the normal 55. Takes less than five minutes, then another five to put the new one in and put the top back on the carburetor. Automatic Rob responded - I can buy main jets "over the counter" at my local VW shop here in Australia. Dave bought a Pierburg model 34PICT/3 carburetor from Aircooled.Net, and none of the jets had the sizes stamped on them. A clean plug with a light grey/tan look means the mixture is about right. The carburetor has a 55 idle, X125 main and 125 air correction jet. 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? Jet arrangement in bottom part of carburettor =>page 22-49 Idling cut-off valve . The main jet provides fuel from about 1500 rpm right up to maximum rpm. Jet-A-Vator. For 1600cc engines, use an X130 main jet. This carburetor will NOT work well with cams with over 270 duration, (same as the stock 34-3 carb). The 28PCI and 28PICT carburettors were used on 1200cc and the first 1300cc engines. 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. PRICES are subject to change without obligation. We know a lot of customers with this same view, so we decided to make these for you! The power jet is usually a size 65. I have lowered the fuel pressure down to 2.5 psi and checked the float bowl fuel height. See the discussion of jetting with the 009 distributor below for needed revisions to the jetting of the 34 PICT/3 carburetor in this application. Dave replaced the main, idle and air correction jets so he knew what he had. for IDFs, make the idle jet 1.25 the size of the throttle body. Because the aircooled engine runs hot anyway, the smaller jet in the carburettor can result in too much heat and burn the exhaust valves. Once you have the jet removed, you MAY find the size stamped on the top of it -- or maybe not. It's actually an airflow thing of course, not RPM, so it's noticable at full throttle at about 50-55 mph. 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. Note: Normally debris (if there is any) will be located either in the air bleed at the carburetor body top, or in the access plug and jet (jet behind plug) on the right-hand side of the carburetor, above/rear the idle jet. Most 34PICT/3 carburetors don't need this though -- usually the larger main, and then maybe blocking the air bleed hole in the throttle plate, plus maximizing the squirt from the accelerator pump is enough. At the beginning I started to use a Solex 30 PICT-2. 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. 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. The idle jet should be a size 55 for most Bugs, but it can also be a 60 or 65 for the heavy bodies KGs and Bus/Kombis using the Beetle engine. IDLE JET .55 .65 .60 (d) VENTURII 40mm .

Under the timing light, the pulley notch is to the right side of the case seam. If it seems a little rich at higher speeds (plugs sooty after a plug read) then try the 130Z air correction jet. An altitude of 5000 feet is roughly equivalent to a one size main jet difference. 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. Or should I open what I have or rob from a newer model? 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. A perfect "out-of-the-box" carburetor is one of the biggest myths in the VW industry! The 1600cc DP can flow more air than the 1600cc SP and smaller engines. VW set up a vacuum advance distributor, and the stock jetting in a 34 pict 3 for a 100% stock engine. The VW 105-1 Air Correction Jet would be 125z.

Every engine is different, so strongly consider getting our micro sized idle jets to really dial it in. More throttle does make it go away. 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. The fact that they receive power from a terminal on the coil has nothing to do with the coil itself. Where the early style carburettor has the idle cut-off solenoid on the RIGHT side of the carburettor, that solenoid sits in the back of the idle jet. Some of you may be using this Carburetor. If you try removing the idle shut-off valve and the air correction jet (the brass bolt head in between the float bowl and the main throat) and the idle jet itself, and then blast air through the passages in both directions, that might get it. Nothing is exactly that linear of course as the jets are all different sizes, but maybe it helps visualise the problem of keeping the fuel flow balanced at different rpm/airflows. But engines do differ a little, and the sizes above are "ball park" figures rather than definitive. Solex 34 pict 3 jet size. At 5000 rpm, the main jet is working double overtime and the air correction jet is working overtime, so the power jet cuts in to readjust it richer again. Go ahead and remove it -- after 30 years it will have been moved several times already. 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 venturi sizes listed below are the sizes supplied by Weber in new carburetors. All Solex carburetors tend to run lean at high power settings (high rpm and open throttle). Rebuild. 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). Re: 34 PICT 3 Adjustment Woes. Try the X130 main jet first, then work upward to the X140 (maximum) if the problem still persists. 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. The air correction jet prevents the mixture going over-rich at high rpm (again, smaller numbers means richer for this jet). On the premise that the 1600cc engine likes to run just a tad rich, many people will change out the main jet for a size X130. Following that is a listing of the parts, giving It sounds like the jets you have in there are set for a lean running Bug (50 idle, 125 main and 135 air correction makes for slightly lean through the rpm range with the light bug body). Note: The manuals say that you should not remove the volume control screw, as it is set at the factory. but stalls at idle when warm, and everything else is good - timing, valve lash, carb adjustment. This will richen the mixture and help eliminate any 009 flat spots. Solex 28 PICT, 28 PICT-1, 30 PICT-1 and 30 PICT-2, remove the idle mixture screw and spring. 737-240.

Size 24 MB File Type PDF File Get free Mikuni Solex Service Manual Solex . general exploded view of the 34PICT/3 Carburetor is shown in the This jet is critical to engine flexibility and economy. Remember on the 34PICT-3 the idle jet affects drivability and power up to about 2,000 rpm when the main jet takes over. 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). 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. 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. Turn the ignition on (but do not start the engine). Idle jets are available in small increments. If the fuel/air mixture is too lean, the engine will run very hot, stumble, and misfire -- and burnt valves can be the result. The Power Fuel System Dispensing Nozzle for the VW 105-1 would be 0.50 with no check ball. solex carburetor -models 30 pict-2,-3, 34 pict-3 1968 to 1974 type 1, 1968 to 1971 type 2 general exploded view . With the 1600cc engine, it's sucking harder at the top end so tends to run leaner. If the idle RPM peaks at 2-3 1/2 turns out, you're OK. I have 4-5 I've collected over the years, and the smaller ones can be re-drilled to the larger sizes. Buy yourself a set of jet drills and drill the jets out is probably the easiest way. body (5). Checking and adjusting cold idle speed =>page 22-53 Throttle valve positioner 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). 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. Volume control screw O-ring (18) This carburettor usually comes with a very lean main jet as an emissions thing (size 120 or even smaller) and a larger than normal idle jet to compensate. Notify me about replies to my post Reply V. . 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. "Leaving it alone" is fine for a new carburettor but silly when the engines are all at least 30 years old and in different states of health. 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. can find them - rare!). 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. And the second issue is the presence of Ethanol (alcohol) in gasolines. (See our Automatic Choke Discussion and Adjustment Procedure.). See our. And I have the by pass air cut off valve (12V thing) on the left side (as same as on the 30 PICT-3, which I have seen on pictures in books, but the by pass air cut of valve were always shown on the right side). On the /3 and /4 carburetors - it looks like a bolt with a tiny silver plug in the center. Normally, shops stock them in round sizes of "5"s, like 50, 55, 60, etc. We are still processing and shipping orders from our warehouse as normal even while our site is offline. Milease has increased by 90 miles per tank. The 30PICT/1 carburetor was used on most 1300cc engines (about 1964 to 1967, and in some countries, up to 1970). 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. Others are upset by a backfiring, or smoke belching monster. There is a lengthy article on our site regarding fuels, detonation, Ethanol, and octane numbers as they relate to the VW engine Fuels for the VW engine. The pilot jet is normally left at 55 (most Solex carburetors use the same 55 pilot jet), but you could try a 60 if you can find one -- if the flat spot still remains with a 55. You . Lightly lubricate the choke valve shaft and throttle valve shaft with engine oil and the external linkage with molybdenum grease. Seller pays for return postage. Location: Miami. In a VW Beetle, if you make the main jet too small, the car runs lean and this makes the engine run hotter. "N" on the schematic is the coil. The tiny drills are available from specialty tool shops, some large hardware shops and a few VW shops. Disconnect the electrical lead from the valve, then touch it to the connector again. We provide the classic VW hobby with tech tips, project advice, and quality parts for VW Restoration, VW Performance and Custom Aircooled VW projects. When used with the heavy bodied Type 2 vehicle and a vacuum distributor, it should work well with a 60 or 65 idle jet, 125 (or just maybe 127.5) main jet and a 125 air correction jet. The X127.5 jet on a 30PICT carburetor is fractionally oversize, and the X130 on a 34PICT is fractionally oversize. So with a vacuum distributor, using a 55 idle, X130 or X132.5 main and about a 100 - 120Z air correction jet should provide good mixture for a 1776, without affecting fuel economy to badly (fuel consumption WILL be a little higher with the larger capacity though). Details. 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 . Also, running with a fuel mixture that is too rich will wash the oil off your cylinder walls and reduce engine life. = Uses .0 Bypass: WEBER 34 ICT: Factory Sizes: Single Carb: Dual Carbs: AIR CORRECTION 1.60 N/A 1.60 EMULSION TUBE F-78 N/A MAIN . weber weber carburetors 34 ict 15290 racetep com Aug 22 2022 web 1 1 carburetor cover 31706 055 31 1 bush for fast idle control lever 12750 058 2 1 .
