Rebuilding some gl1100 carbs. Kits came with what appear to be slow jets, but can't find them nowhere in the carb body. Am I missing something? Its an 81' There is a port right next to the main jet, that looks like there may be a jet down in there , but there is no slot in it to remove it. Any help on this issue. I was told that these are really fussy. Also, when setting the idle mixture screws, the dealer manual says 80-81 1-3/4 turns out and 82-83 3 turns out. This is an 81 and the original screws where all about 3 turns out. Play it by the book, or go by what the old were set at ? Any advise?
