Friends, lovers, Chevy cretins....Let's unf*ck a Six Pack

Actually the outboard carbs have idle mixture screws.
I just rebuilt 2 sets. One is a vacuum setup and the other is a mechanical set.

Call Allstate carburetors in NY. for kits / parts.
These guys are great help. Jim or Jarred.

They will have the kits and are very knowledgeable.
