A buddy of mine bought a '68 Road Runner restored about a year ago. Its all factory and the 383 is supposed to be rebuilt to factory specs, the one incorrect thing on it is the original Carter AVS has been replaced with the 750 Edelbrock, I guess its the Thunder Series?

Anyway my buddy, Steve, is a pretty sharp tuner. Hes owned many cars over the years and they've all been pretty much stock but he spent hours tuning all of them and got them to really fly. This car is just a dog. It will get moving, and it could be worse, but it feels like its got a 383 2 barrel really. He can't figure out this engine out, mostly the Edelbrock carb and thinks its the problem. I mentioned to him that theres alot of complaints about them and told him Id see if I could find anything out.

Any tips for getting these things to work? Are they basically just junk, or can the problems be fixed with some work? He doesn't have money for a new carb, so hes trying to fix what he has.
