2622/066 Float bowl drain plug washer
Sealing washer for the float bowl drain plug on the Amal MkII Concentric carburetor.
This is the small washer that seats under the float bowl drain plug on the Amal MkII Concentric carburetor. It's a simple sealing washer, but it's the kind of part that's easy to lose track of when you're pulling a carb apart for a clean-out or float service, and a tired one will leave a fuel seep at the bottom of the bowl.

The factory number for this washer is 2622/066, and it shows up in the parts books alongside the T140E and T140D Amal MkII Concentric carburetor listings. If you're working from an older parts book you may see it noted differently, but the current factory reference is 2622066.
Good practice is to replace this washer any time you have the drain plug out, rather than reusing a worn one and hoping it seals. It's a cheap piece of insurance against a fuel bowl that won't hold a tight seal.
