On launch the ball is supposed to launch into the Lock Ball slot and It used to go in there 90%+ of the time but now it never does. The machine is perfect balanced.
I did try swapping the coil with the kick back coil as they are the same one that did not work. I also tried messing with the coil by removing some of the coil to make it stronger. This fixed the problem for maybe 15 games and now back to not launching correctly.
Does anyone have any suggestions on what else to try?
thanks
