Chuck and Gmask, thanks for your replies. Chuck, I noticed that I do not have a heat riser tube from the exhaust to the air breather. I am thinking that I'm getting some "carb ice" when it's really cold which is causing my lurching problems. It's been very cold here this winter and I talked to the guy I bought the car from, and he said that he doesn't remebere there ever being a tube because it just gets too hot here in Oklahoma. Do you think this could be causing my problem? What are the consequences of putting this tube in place? I know the heat could end up causing problems as well - should I remove the tube in the summer? Also, I don't think this would have anything to do with my hard,cold start problem, would it? Once the car has been running in the morning, it starts much easier later in the day, even if it's still real cold. Thanks for your help.

Ryan
