>>BTW. Has anyone got any smart ways of setting the idle air screw? I am running 32PDSIT's on my beetle, everything is stock as it is on a Type III except for the linkage which is a custom one. At the moment I am only getting about 13 miles per gallon! I can get the idle screw spot on, but it is harder to get the idle air screw right.<< A really oversimplified version of volume screw adjustment is: carefully turn volume screws all the way in until they reach the seats, then back out 1.5 turns. Then start engine, warm up, turn both screws in slowly and equally until engine speed begins to drop, then back out until engine runs smoothly, then out an additional 1/4 turn. This assumes that you've balanced the carbs with a Uni-Syn at 650-700 rpm before the volume adjustment and again after (with right side throttle linkage disconnected). And that the valves and timing are already adjusted. Personally I find that this gives a slightly too rich mixture, and I have to turn the screws back in 1/4 turn or so. VW published a nice pocket brochure that explains the above in much more detail. If anyone wants a copy of it let me know.
