The booster issue is all the carbs have the same exact booster in the same exact place over the venturi. When you look at a stock AFB or AVS, take note to the boosters place over-in the venturi. There all places in different spots. Another thing is all the booster parts in the carb are the same. Take the EDELBROCK poster out and compare it to a few other Carter boosters. You will note the amount of holes, where there placed and how big the holes are. The last thing is the 750 secondary booster has a limited orifice to let fuel up into the ring over the booster which limits jetting to that tubes size. Just cut the bottom off and you should be good to go.
