Thanks TBone, I had the carb shop in CA rebuild the QJet, re bushed the throttle shaft, well plugs, float and major clean up and adjustment. They even dynoed it on a 350 before shipping it back to me. I removed the cover off the heat stove to check its movement , put the spring in a pan of water on the kitchen stove, seem to work ok but not really sure it moved as much as it should. Reinstalled the carb, still runs crappy when cold. Does the vacuum controlled air cleaner valve that controls the heat riser on drivers side have a big impact on cold weather start up ? Mine is not connected at the moment....thanks again..
