You aren't saying what year engine and/or what carb you're referring to. My '38 W1 has a spring that returns the choke butterfly to the open position. If you have a W1 the spring may be broken or the shaft sticky enough that the spring can't pull it back or the clamp that holds the choke cable wire isn't tight allowing the wire to slide through the clamp. FYI this thread will probably get moved to the engine shop forum. This is the electrical bay for electricity related issues.
