I have read that the rebuilt carbs that are sold by parts houses are assembled from a pile of parts. There were many different configurations for the Rochester carbs so what you get is a frankencarb. I think you'd be better off to have yours rebuilt. It may cost a little more but you get what you pay for.

Two rebuilders are highly recommended though I have never used either. Carbking is active on this forum. 573-392-7378 (9-4 Mon-Tues). The other is Larry Isgro Carburetors. [email protected] or (516) 783-1041
