Oh my oh my, the patience many of us have developed over the humble Model B and their derivatives. For being one of the of the simplest carburetors ever built it is the most cantankerous dang things to get right. I have worked on them for 52 years and I swear I still have problems. I have all kinds of precision tools and a clean room but the most important item is a strong magnifier and plenty of canned air. Doc.
