Start with the basics - make sure the timing is correct. If the carb has been off the car sitting on a shelf, check for vacuum leaks, float setting, stuck needle and seat. The Edelbrock carbs are easy to rebuild and the kits are readily available at any national speed type shop.

I tend to agree with Quenton - check timing first. If the engine was in the car when the body work was done with the carb on it, then it may be worth the time to pull the carb apart and clean it up.

Hope this helps.
