Main jet (150)
Amal 150 main jet for the carburetor's main fuel circuit, listed as 19-3099 / 376/100.
This is an Amal main jet, size 150, listed in our records under 19-3099 and also known by the number 376/100. The main jet controls fuel delivery through the carburetor's main circuit, mostly under higher throttle openings once the pilot and needle jet circuits stop dominating the mixture.

It shows up in our catalog inside the carburetor and throttle linkage section, and our only record of it dates to 1973. As with any jet, the size stamped on it (150 here) is specific to the tuning that carburetor was set up with, so swap it for the same numbered jet or work with someone who knows how to re-jet safely rather than guessing at a substitute.
We don't have more detail on this one beyond the size and the fact it's an Amal part. Call the shop if you want to confirm it matches what's currently in your carb before you order.
