I had that...

check choke (that's what happened to me ... choke wouldn't open) - I just used duct tape and bailing wire to hold 'er wide open (this is for if the choke is fully closed 24-7). Then, just tune it. You'll be surprised how bad a car on a winter tune will run when it gets 80+ out. It's gotten very hot very fast, and it messes with carb'd engines real bad.
