Hesitation When Accelerating

[eschaider]

Patrick is providing some very good (and easy to do) guidance for you ZZ. Whatever you do, do not spend the $600, or so, to replace your current 770 carb with a smaller one. In addition to being the wrong thing to do, that will make your wallet $600 or so lighter, your engine less powerful and your car less fun to drive. As long as you are using a Holley you might want to consider getting some additional knowledge about the carburetor, how it works and how to tune it. You're going to be living with it for a while and knowing how to operate it sure beats not.

Replacing the carb with a mechanical secondary Holley is a great idea even if you can get the Street Avenger to perform properly. Vacuum secondary carbs are great for heavier cars but not ours. Even Holley recommends a mechanical secondary carb for cars as light as ours.
I, too, had a roush engine with that street avenger carb. Car performed ok, but when I replaced it with a mechanical secondary carb, it was like a light switch was turned on. Woke that engine right up.
Good luck.
