I dunno bout you other carbed guys, but my car has to warm up for a few minutes or it will "bog" when i floor it pretty bad. also when i first got the car it had been sitting for a number of years, so drained all the fuel lines and stuff and it was good to go. still on cool days or the first 10 min right after start up on anyday it will hesitate, just give it some time and try again, if that doesnt work, come back here[8D]

I was sixteen and kragen gave me the wrong kit.

1990mustanglx: It's way under 100 to rebuild your carb (still waiting for those pictures)
