Looking for correct carb mounting studs. (Problem solved)
They are studs. 3/8 - 18 in the manifold and 3/8 - 24 nut. The length above the coarse 3/8 - 18 thread should include Thick factory gasket and carb plus 1/2 for the nut. I believe the total length is 1 1/2 "
Make sure you use the thick heat dissipator gasket so the choke spring is the correct length. If you just use the thin gasket the choke will not open correctly
