I suppose since you have the heat tube hole in the mainfold welded up that means you have replaced the carb with one that has a electric choke? The reason there is a heat tube from the manifold is to allow the heat to travel up the tube as the engine warms up to the bimetallic coil in the choke..... which uncoils as it is warmed and kicks off the choke. If you have a standard carb without the heat tube hooked up your choke will work but will take forever to kick off in the winter
