SCREW THROTTLE ADJUST SS
Amal carburetor throttle adjuster screw, part 210/007 (formerly 99-0337), used to fine-tune idle at the carb.
This is the throttle adjuster screw for Amal carburetors, the small knurled screw at the top of the slide cap that lets you fine-tune idle and cable slack right at the carb. It's the part you turn to set a smooth idle without having to touch the cable adjusters further down the line. Catalog records show it under part number 210/007, with an older factory number of 99-0337 for the same piece if you're working from an earlier parts book.

It shows up in the control cable sections of the parts books across a wide span of years, which tells us it's a common wear-and-tune item rather than something tied to one specific model. If your old one is worn, buggered up, or just missing, this is a straightforward swap.
Given how often these get lost or stripped out from repeated adjustment, it's worth keeping a spare in the toolbox.
