That means that the jetting requirement for any VW using ethanol-added gasoline/petrol is different to those using straight hydrocarbon gasoline/petrol. Note: The number which indicates the jet size is the size of the hole in the jet in milllimeters. The proprietor of Aircooled.Net thinks the main jet is a size X130, and the idle jet is size 50.)

The venturi sizes listed below are the sizes supplied by Weber in new carburetors. 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). You can also get detonation (pinging/knocking) if the engine gets too hot. So there is a HUGE difference in hole size compared to the main fuel jet. 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). 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). Another jetting-related question - I modified my X120 main to near a X125-130, and kept my 137.5Z air correction jets. . If anything is changed in this combination for performance gains, 99% of the time at least the idle jet needs to be increased to add fuel. -there is fuel in the 34 PICT 3 resevior.

The 34PICT/3 carburetor is usually used on 1600cc or larger engines. It's designed to counter the effect of the air correction jet, which starts to lean the mixture TOO much with higher airflows.

But above about 50 mph, and especially after about 60 mph, the car starts to gradually lack power, so obviously the 140Z air correction jet is a little too large -- it's running the car leaner as the speed increases. 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. 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.

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. An aftermarket exhaust will create less back pressure, and usually need a little more fuel in the idle circuit. A loss of power is the result -- about 58hp instead of 60hp. These plates provide restriction and also atomize the fuel/air mix better for greater fuel economy. The larger 34PICT carburetor should have the larger X127.5 main jet, and since the larger 34PICT carburetor doesn't have the extreme airflow with a 1600cc DP engine that the 30PICT carburetor does, the over-rich problem is reduced, so you use a SMALLER air correction jet - less correction is needed.

On some models (the H30/31 for example) it is angled slightly towards the back of the car. The power jet counters the leaner condition at higher rpms, richening the mixture back into balance again. 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 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. The air correction jet prevents the mixture going over-rich at high rpm (again, smaller numbers means richer for this jet). As a result, we have had to change our BACKORDER FULFILLMENT PROCEDURES.

The idle cut-off valve receives power from the positive (+) terminal on the coil (#15) -- see the schematic which shows this wiring arrangement. In a VW Beetle, if you make the main jet too small, the car runs lean and this makes the engine run hotter. Rob responded - If you still have a vacuum distributor - yes. "N" on the schematic is the coil. It's actually much easier to do if you remove the top of the carburetor and the float. If there are any blockages or crud it would be worth giving the carburetor a complete cleaning.

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.

All three of these jets can be changed. It's important that you get it right. 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 009 centrifugal-advance distributor can not sense throttle position (engine load), only engine revolutions, so it's not ideal in all circumstances.
