Carter "Carstarter"

My 1948 Packard with a Carter carburator has the "Carstarter" or throttle activated starter. My problem is that it will still activate the starter after the engine is running. I have read and understand the manufacturers information on how it's supposed to work. In my case, after the engine starts it does not always "suck up" the steel ball that acts as the link between the throttle shaft and the electrical switch. In addition as you accelerate the manifold vacuum drops (normal) and the ball falls back down. It should be blocked by the throttle shaft but falls thru allowing it to activate the starter while running.
It appears the steel ball in my car is of too small a diameter.
Does anyone know what size it should be?
