AVS problems

It could be a number of things. B4 starting in the morning or first cold start of the day, remove the air cleaner. Is the choke partly closed? If so, push the throttle right to the floor, let off, is the choke fully closed? Is so start the car. Is it on fast idle? If so let it warm up some b4 kicking it off fast idle. Let it fully warm up, then try adjusting the mixture screws. Do they make a difference? Better or worse? If the choke needs adjustment. I can help u with that too. Kim
