Turn the Bypass Screw (the larger one) out a couple of turns, to get things started. Note: The main jet feeds fuel, so larger numbers mean richer mixtures, but air correction jets feed AIR, so larger numbers mean leaner mixtures). Milease has increased by 90 miles per tank. It should not need to be bigger than that with a vacuum distributor (009 distributors need richer mixtures). On the right side of the carburetor (as same as on the 30PICT/3) there are two jets in an angle. 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.

Once again, try the conservative approach first, then get richer only if you have to. If the idle RPM peaks at 2-3 1/2 turns out, you're OK. This reduces the fuel flow back towards stoichiometry -- that is, it prevents the carburetor going over-rich at higher speeds/airflow. Carburetor Installation. were visibly larger in the new jets than the old ones. "Lean" means less fuel with the same amount of air, and of course "rich" is the opposite. Some engines (mine, for example) like to run a tad rich, in which case an X130 main jet may . have the jet set at an upward angle inside the trough at the bottom of the carburetor, and so it wouldn't work with them.

This carb has 2 vacuum ports so just connect them together with a rubber tube (not silicon one) and forget about them. With lean jetting you are likely to need more throttle and have slightly worse fuel economy - using the slightly richer settings I'd suggested above will give you a little more power and a cooler running engine, so hopefully fuel economy will improve a little, but don't expect too much - fuel economy with the heavy Type 2 body is never very good. The use of VW, Volkswagen and any model names and numbers is for the sole purpose of description of parts application.
