2928/071 Needle retaining disc
Needle retaining disc for the Amal Mk II Concentric carburetor, PN 99-7072 (also listed as 2928071).
This is the needle retaining disc for the Amal Mk II Concentric carburetor, part number 99-7072, also carried under the factory number 2928071 in later listings. It's a small internal piece that sits inside the carb body and holds the jet needle in place so it stays seated and moves correctly as the throttle opens and closes.

Our catalog shows this disc appearing on Mk II Concentric carburetors used on T140E and T140D applications from 1979 to 1983. If you're rebuilding a Mk II Concentric and the needle's been rattling around or won't stay put, this disc is a likely culprit worth checking.
Since it's a small carb internal, it's easy to lose track of during a strip-down - keep it with the needle and jet when you pull the slide assembly apart so nothing goes missing before reassembly.
