MAIN JET- MONOBLOC MK1 MK2
Main jet for the Amal Monobloc Mk1/Mk2 carburetor, part of the main fuel circuit.
This is a main jet for the Amal Monobloc carburetor, Mk1 and Mk2 versions. The main jet controls fuel delivery through the carb's main circuit, mostly under throttle openings above about a third, and it's one of the parts people fiddle with most when tuning a Monobloc for a given engine and exhaust setup.

Our catalog entry on this one is brief, so we're not going to guess at exact sizing beyond what's on the part itself. The jet is stamped with its size number, which is what you want to check against your current jet before ordering a replacement or trying a step up or down.
If you're not sure which jet is currently in your carb or what size you're running now, pull the float bowl and check the number stamped on the jet before you call it in.
