Air valve guide
Amal carburetor air valve guide listed for TR6 and T120 carb figures, 1964-1967.
29/057 is an Amal carburetor part, listed as an air valve guide in the parts books. It shows up in the Amal Carburetter figures for the TR6 and T120, so it's a piece that lives inside the carb body rather than out on the engine or frame.

The catalog notes tie it to the 1964-1967 span of listings, and it turns up across a handful of entries in that window. If you're rebuilding an Amal carb off a TR6 or T120 from that era and the slide or air valve isn't moving smoothly, this guide is one of the small internal pieces worth checking.
We don't have more detail on this one beyond what's in the parts book. Confirm it matches what's in your carb before ordering, since Amal used a number of similar small internal guides and springs across different carb models.
Sorry if we got something wrong here. If you think this information isn't correct, .
