Main jet (170)
Amal-type main jet, size 170, part number 376-100, for Amal Monobloc/Concentric carburetors.
This is a main jet for an Amal carburetor, size 170, catalog number 376-100. It's the fixed-size brass jet that sits in the float bowl and meters fuel into the main airstream once the throttle opens past the pilot/idle circuit range - basically the part that sets how rich or lean the carb runs at cruise and full throttle.

The 376-100 number is Amal's own jet numbering, with the last digits (170 here) indicating the specific jet size. It's a listing that appears once in our catalog under the CARBURETTOR figure, tied to a 1968 fitment record, so it's a small, specific part rather than something with a long production run behind it in our books.
Main jets are cheap to get wrong and easy to swap, so if you're chasing a flat spot or fouling plugs, this is one of the first things worth pulling and checking against what your carb actually calls for. Give the shop a call if you want to confirm this jet size is right for your setup before ordering.
