on my 3 circuit 9375 it definetly runs better through low rpm with 25 shooters. Thought they were way to small when I bought the carb and went 35's sputtered all the way through first. ended up back at 25's on my old 542 they worked best too??
This is because the anullar discharge boosters rain fuel with a low signal so all that extra shot is unneeded.





What color cam did you have on it and was it in the 1 or 2 position ?
