Renew sleeves on flipper, pop bumper and sling coils
New nylon sleeves on the flipper, pop bumper and slingshot coils make the game noticeably snappier; other coils don't need it. Metal sleeves should be swapped for nylon; if a metal sleeve won't come out, the coil must be replaced. Under the playfield, two screws hold each pop or sling coil bracket.
