Follow this link for the 2100 carburetor exploded view and rebuilding steps. This is not a hard carburetor to rebuild and is fairly forgiving. It is a very good carburetor providing long life and good 2bbl performance.
I am trying to get an Autolite 4 bbl. carburetor disassembled to get pictures. However 2 of the ones I have are not budging when trying to remove the upper air horn screws. I’ll post a section on them later.
