If yours is a Fed. car, the carburetor is the simplest of three variations that were used over the '73-'76 run of carbureted engines. I have one of that that variation in rebuild now. All were subject to warping, in varying degrees.
Wow, that's good info, thanks. I'll check for that next time I go to look at it. What causes a warped carburetor? Is there any remedy, other than a replacement?
