thermoquad???

Just say NO to any mass rebuilt type carburetor. The thermo quad in particular, has numerous plated parts, and they should be properly replated during a rebuild, not something that can really be done at home
I agree. Years ago, I once walked thru a "rebuild" shop on Capitol Hill in Seattle. They litterally had a pile of parts, a foot and a half high, of Rochester 2bbl parts. Must have been twenty carbs all mixed up.There was a guy sitting at a bench grabbing parts one by one trying to assemble some Frankenstein carburetors.
