MAIN JET PRE-MONOBLOC 210
A size 210 main jet for the pre-Monobloc Amal carburetor.
This is a main jet for the pre-Monobloc Amal carburetor, sized 210. Pre-Monobloc refers to the earlier style of Amal carb body used before the Monobloc series came along, and these jets are specific to that carb family, not interchangeable with later Monobloc jets.

The main jet controls fuel delivery through the mid-to-upper throttle range, and the number stamped on it (210 here) is the jet's size designation. If you're rebuilding or tuning a pre-Monobloc carb, jets like this one are cheap to keep a few sizes of on hand for getting the mixture right.
We don't have much more detail on file for this one beyond the jet size and carb type. If you're not sure which carb you're running, check the body casting before ordering to make sure pre-Monobloc is right for your setup.
