q-jet won\'t idle. I just had a quadrajet rebuilt and through it on and it won't idle. It will rev to about 2000 and then slowly make its way down to about 800 and then it revs back up. I will admit I don't know much about carbs so any info will help. I don't want to just start turning screws and completely screw it up. Also I am running a healty cam and wondered if vacum has anything to do with it. Thanks guys.
