I have noticed the easiest way to tell if the carbs are not in sync is to
quickly snap the thottle a bit and you will hear a sort of a cough, if they
are in sync, it should sound smooth when you do this.

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.
