Thanks Magnum. I did go to the track yesterday and it did not go well. Car would launch flood out die. did it twice. I think the choke pull off is the culprit. It also functions to slow the opening of the secondary air valve. I've taken the choke pull off... off. This only happens at the drags when I really hammer it quickly.(in front of hundreds of people!) I'll know next week. I'm going to try again!!!
