I can't get the ball to circle the spin out ramp often enough to score 100 points. It always falls short - runs out of steam - at around 50. The sound from the ball shooter is very loud and annoying indicating a good spring action? I suspect there is either a weak shooter spring or a short shooter rod? The spring is red in color. Is there anybody out there who can give me any ideas, may be part numbers for the correct shooter parts? Fully appreciate any help I can get.
