When I said cold, I mean the engine temperature not the weather. 8) If the car is running fine otherwise then I would guess you have a fuel leak somewhere. To check the choke take the air cleaner off and look at the top of the carb there should be a plate on top that blocks some of the airflow into the carb when the engine is cold. An automatic choke, if it is working properly, should rotate and stand on its end this would fully open the top of the carb as the engine temperature comes up. Of course a manual choke should do the same when you push the knob in. while you got the air cleaner off look for fuel leaks around the carb, mainly the fuel inlet and the top of the accelerator pump. Check your fuel pump and fuel lines too I've seen em leak when the engine is cold and stop or slow way down as things warm up. Hope this helps.
