Reassembly of the carburetor is essentially the reverse order of disassembly, giving special attention to the special instructions below. Size 24 MB File Type PDF File Get free Mikuni Solex Service Manual Solex . 34 PICT Carburetor Combination. Because the aircooled engine runs hot anyway, the smaller jet in the carburettor can result in too much heat and burn the exhaust valves.

This will have the main jet supplying the fuel, and read the plug again. Aircooled.Net, Inc. is in no way affiliated or associated with Volkswagen AG or Volkswagen ("VW") of America. Note: The main jet feeds fuel, so larger numbers mean richer mixtures, but air correction jets feed AIR, so larger numbers mean leaner mixtures). Others are upset by a backfiring, or smoke belching monster. IDLE JET .55 .65 .60 (d) VENTURII 40mm . 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. Lightly lubricate the choke valve shaft and throttle valve shaft with engine oil and the external linkage with molybdenum grease. 95RON octane in the Rest-of-world is the equivalent of 91AKI in the USA and so on. 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. This is not correct. 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. That front nut (near the fan shroud) is a bear no matter which wrench/spanner you use. The idle cut-off valve is not strictly a "jet," but this is a good place to discuss it. An altitude of 5000 feet is roughly equivalent to a one size main jet difference. The carburetor idle circuit controls how much fuel you have at idle.

These plates provide restriction and also atomize the fuel/air mix better for greater fuel economy. Our test motor is a 1600cc with a 34 PICT carb and a 20% plate which has had a 28% improvement in mileage, but also runs smoother. 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. E10 usually needs a larger main jet and might also need a larger idle jet. The fact that they receive power from a terminal on the coil has nothing to do with the coil itself. 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. 3. If it's working, you'll hear a clicking sound as the relay pulls in. Normally, for stock daily-driver Bugs, you will find that an idle jet size of 55-60 is right for you.

All suggestions here are just that - suggestions. Our 74 Super has a tube running from the 34 PICT 3 down, and is . The 205L number is a Bosch number, the other one is a VW number. 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. 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. 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. 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.

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. 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. 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!

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. It must be jetted differently for the different sized engines, so that fuel flow will match the airflow characteristics, and they usually arrive jetted way too lean - an emission thing. Remember on the 34PICT-3 the idle jet affects drivability and power up to about 2,000 rpm when the main jet takes over. "N" on the schematic is the coil. A 44 IDF would need a 55 idle jet, and a 48 IDF would need a 60 idle jet. PRODUCT AVAILABILITY can vary and short-term backorders are common.

Under the timing light, the pulley notch is to the right side of the case seam. 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. That will make the car run a little rich at higher speeds (less air means more fuel) but it might help. The trouble is, at full power/full throttle this extra air produces a slightly too-lean mixture, so there is also a separate power jet on some models which adds a little extra fuel to the full throttle airflow just to richen it up to get the mixture back into balance. 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. If it takes 4 1/2 to 6 turns to peak, go up a size or (1/2 size if you.

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). 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). But different gears and different rpm doesn't. The air correction jet prevents the mixture going over-rich at high rpm (again, smaller numbers means richer for this jet). 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. Look down into the top of the carburetor to make sure that the screwdriver is squarely in the slot in the jet and that the threads line up squarely, then just screw it in (the small screw driver sits deep in the slot in the jet and helps line it up).

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. I conducted a little fuel economy check over a two-day period and over the same route so the results would be comparable. Note: The manuals say that you should not remove the volume control screw, as it is set at the factory. In these later models, you can easily change the jet with a medium screwdriver either with the top of the carburetor removed or with the carburetor completely off the car.
