MAIN JET- MONOBLOC MK1 MK2
Main jet for the Amal Monobloc Mk1/Mk2 carburetor, size 300.
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 bigger throttle openings, and it's one of the parts most owners end up swapping when they're tuning a Monobloc-equipped bike for the way it actually runs versus how it ran from the factory.

The part number itself, 376/100-300, follows Amal's own numbering for main jets, with the trailing figures indicating the specific jet size in that range. We don't have more detail on this one beyond what's in the catalog record, so if you're trying to match a jet that's already in your carb, bring it in or give us the number off it before you order.
Worth keeping a small stock of different sizes on hand if you're doing your own jetting work, since these are easy to swap once the float bowl is off.
