Edelbrock tuning issues

Funny how so many people think poor performance is the fault of the carb. So many other things to check BEFORE messing with carb settings. LIke 318willrun said, check the engine timing and let us know what it is set to currently. Does the distributor use vacuum advance? If so, ported or manifold? What kind of ignition are you running? Points, electronic? Stock distributor or aftermarket? What kind of car is engine in? What is the rear gear ratio? Automatic or manual transmission? See, we need more info to point you in the right direction.
