Well f it!... I called Summit and they're sending me another one.. the whole idea of doing this was to have two brand-new identical carburetors that matched each other identically and I mean down to the last screw.. I got two good running carburetors at kind of don't match each other.. I know I'm being picky but what I want is what I want I guess and that's what I paid for.. again I guess the closed mouth don't get fed...
