Anyone able to confirm that a main jet for a Concentric will also fit a Monobloc? I think they do crossover but don’t have enough info in my manuals to say either way.
Also, is the needle jet and needle for a a 375 Monobloc the same as a 376?
Asking because I can find 376 carb needles and needle jets and Concentric main jets in my size online in NZ but not 375. The diiference is in the throat size I think but possibly the needles and needle jets are the same. Not sure about the mains.
Asking for an old BSA, and need a Monobloc 140 main, .1055 needle and needle jet.
