Quoted from bonzo71:When I owned Nip It, I also had he same issue. I found that the metal part the kicks the ball into the trough was worn and would sometimes kick the ball into the air which would slow the travel time to the trough switches. From memory, I bent that part so that the kick of he balll to the trough was smoother with no air balls. Also, I recall bending the metal above he trough track to prevent air balls. It was a bit ugly, but hidden under the apron. The ball(s) must make it to the trough switches quickly, or the ball count will not advance.
I had the same problem with my Fireball - the outhole kicker was gummed up & not kicking the ball quick enough to the trough switches resulting in the timing being out & not advancing correctly, looking at the first vid one scene looks like the ball is being kicked too slow to the trough switch to me.
An easy way to eliminate this as the possible fault is to manually press the outhole switch simulating a drain & right at the exact same time flick the ball by hand up the trough ramp to the trough switch very fast. When I did this it worked perfectly, so I worked out the problem & rebuilt/cleaned the kicker assembly so it was kicking very fast. Never had the problem again.
