Return spring
Amal carburetor return spring listed for the T90 and T100 range, part number 376/109.
This is a return spring for the Amal carburetor used on the T90 and T100 range. It's a small internal spring that pulls a moving part back to its rest position once you let off the throttle - the kind of thing that's easy to overlook until it starts sticking or the throttle doesn't snap shut clean.

The part shows up across several carburetor figures for the T90 and T100, T100C, and T100SS, so it's a common item behind the slide or the mixing chamber depending on which figure you're pulling it from. If your carb feels lazy on the throttle return or hangs at part throttle, a tired or broken return spring is worth checking before you tear into anything bigger.
We don't have more detail on this one beyond the catalog listing, so if you're not sure which carb assembly it belongs to, bring the carb in or give us the numbers off it and we'll confirm before you order.
