Aligning and tightening the flipper
Steps
- Put the white plastic spacer (0.030 in, about three business cards) between the flipper bushing and the pawl.
- Push a toothpick into the factory roll-pin hole behind the flipper and rest the rubbered flipper against it.
- Lift the playfield and tighten the pawl clamp bolt very firmly, then remove the spacer and toothpick.
- Raise both flippers; they should extend equally. A filed coil stop can stop them matching.
