I've got a bad hesitaion on a 78 350 with a Q-jet when its cold. I'm no expert when it comes to tunning carbs. In the morning I can't even get out of the driveway until its been running for at least 5 mins., and I always have to start it 2 or 3 times while I'm waiting. The idle might be a little low but not much if it is. But, should I be playing with the carb or the timming? Or should I try adjusting the choke linkage? Thanks for any help.
