Quoted from MrWizzo:I backed the return springs off one screw on the pawl for less resistance against the plunger, recleaned the flipper cabinet and EOS switches to make sure there was no pitting. The difference was noticeable and immediate.
That helps a lot and costs nothing to boot.
Quoted from MrWizzo:O-din:

^ That or the rubber slip on holders (rin) for plastics work well combating that.
Pbr sells them. Great for easy bulb replacement.
