Jet holder

Amal carburetor jet holder for the T140V, PN 99-1034 (also listed as 622/128).

PN · 99-1034 / 622/128

This is the jet holder for the Amal carburetor used on the T140V, the part that holds the main jet in place down in the body of the carb. It's a small piece but it matters - if it's worn, cracked, or the threads are chewed up, you can get fuel leaks or an air leak that throws off your mixture no matter how carefully you've set the pilot and needle.

The catalog lists this under 99-1034, with 622/128 as the Amal-style alternate number for the same piece. It shows up in the T140V carburetor listings we have on file from the mid-to-late '70s.

When you're pulling the carb apart for a clean or a rebuild, it's worth a look at the jet holder along with the jet itself - it's an easy thing to overlook while you're focused on the float bowl and needle jet.
