I'm working on a Royal Flush Em. Both the left and right flippers have a considerable amount of flipper buzz as does the gate when opening. Is there a way to
fix this? I already changed the coil stops on the flippers, tightened all bolts down. When the flipper energizes this rattling buzzing happens. The springs only
retract the plunger and work fine. I cleaned the plungers and the sleeves, still no change. Anyone have a good solution?
