Float spindle (622/071)
Float spindle for Amal Concentric carburetors, the pivot pin the float hinges on inside the float chamber.
This is a float spindle for Amal Concentric carburetors, the small pivot pin that lets the float assembly hinge up and down inside the float chamber as fuel level rises and falls. It's a simple part but an important one — if the spindle wears or the float hangs up on it, you get flooding or fuel starvation at the carb.

Our records show this number turning up across a long run of Amal Concentric carburetor listings, including Concentric Mk I setups noted for the TR7RV and T140V, plus other Triumph twin carburetor entries spanning from the late 1960s into the mid 1980s. The catalog also carries it under the number 622/071, which is the same physical part under Amal's own numbering.
Because this spindle shows up across so many different carburetor listings rather than one specific model, check what's actually installed on your carb before ordering — Concentric bodies and internals varied over the years even when the basic float-and-spindle arrangement stayed the same.
