Converting older flippers to the later return spring
Steps
- Pre-1992 flippers use a cone spring over the plunger that chews the link and breaks; later flippers use a thicker link and an external spring.
- Order the Fliptronics-style pawl assembly.
- Drill a 1/16 inch hole in the bracket that holds the EOS capacitor to anchor the new spring.
