Main jet (230) (376/100)
A 230 main jet (376/100) for an Amal carburetor, as fitted on 1969 TR6R, TR6C, and T120R listings.
This is a main jet for an Amal carburetor, size 230, catalog-numbered 376/100. The main jet controls fuel delivery through the mid-to-upper throttle range, and swapping jet sizes is one of the standard ways to tune an Amal carb for altitude, exhaust changes, or general running condition.

The catalog shows this jet appearing in the Amal carburetor figures for the TR6R, TR6C, and T120R listings from 1969. If you're rebuilding or re-jetting an Amal off one of these bikes, this is the part number to check against what's currently in the float bowl.
Main jets are small and easy to lose track of, so it's worth confirming the number stamped on your old jet against 230/376-100 before ordering, since Amal used similar numbering across a range of sizes.
