I tried to fine adjust my switches in the swamp, but balls stay stuck at some point(s) or move slowly from the upper to the lower, then to the eject switch. It is painful as a multiball is never good as the 3 balls do not come at the same speed. Sometimes, the game is waiting for the balls to pass the 3 + 1 switches. I bent the switch wires to get a minimal resistance for the balls and close the microswitch button very quickly. Even with that, it is not satisfactory ... should I raise the back legs at the max ?
