I have a couple machines that will very occasionally release the ball from the outhole ( after draining) without advancing the ball count. Basically they will act as if there was no score and ball is being returned. I guess my question is what is it that registers that first score of a ball? My thought is that the problem probably lies there, either it’s sticking or the gap is slightly off. I know that this happens once in a while on my Williams Paddock and Strike Zone. it may have happened on Spanish Eyes too. Any thoughts?
