John,
I concur with Tom (ttweed). Good job for a well-written (and accurate) description of the process. Everyone with Webers should save and archive this info.
I'd like to add that small adjustments of the idle mixture screws can make a big difference in the air/fuel mixture at idle. And since the idle mixture on these carbs continues into part-throttle operation, some fuel economies can be found in this area. Most cruising, even at highway speeds, is done at part throttle. I used one of the popular DIY exhaust gas analyzers to fine tune the idle mixture. My idle mixture went from from 8% CO down to 4% in just a few fractions of a turn of each adjuster. Mileage went up too which shows you how far off my adjustments were.
