BODY, BOTTOM HALF
Bottom half of an Amal carburetor body, part 313/021.
This is the bottom half of the carburetor body for an Amal instrument, part number 313/021. It shows up repeatedly in the catalog across control-cable and handlebar-and-controls figures, which tells us it's tied into the control-side setup on the machine rather than being a standalone float bowl or top cap piece.

The carburetor body is the main casting that everything else bolts to or slides into - jets, slide, float chamber connections, and the mounting flange all reference off this piece. If yours has worn, cracked, or stripped threads, this is the part you're replacing rather than trying to repair.
Given the age and the fact that this number appears across a run of years in the parts books, double check the casting against what's on your bike before you order. Amal bodies changed in small ways across production, and matching the physical part in hand beats matching by number alone. Call the shop if you want us to confirm before you order.
