It would be nice to understand everything I know about Webers......sigh.
You are having what sounds like a lean pop.
Ball park tuning:
Main jet size 135
Idle jet size 55
Air correction jet size 145
Venturi size 34mm
Etube size, we know but f3 would be better
Tuning should be done after the engine is warm...they all pop when cold....well, mine sure as hell does for the first 2-3 minutes.
In my experience, the idle adjustment screws
should not have to be opened more than 2-
2 1/2 turns to cure a lean pop. If so, larger idle jets are a good idea. The larger
jets will help cure a transition problem also.
Takes a bit of time and ****ing with em' to get a handle it.
I assume you have ballanced the carbs, side to side and end for end.
