Set flipper rest angle and end play

Steps

• Loosen the two pawl set screws that grip the flipper shaft.
• Set each bat so a ball rolling off the inlane meets it the same way on both sides; both bats should rest symmetrically.
• Leave about 1.5 mm (1/16") of up and down play between bat and pawl so the shaft does not bind in the nylon bushing, then tighten.
• If the bats match at rest but not when raised, the plunger, link or coil stop is worn: fit a rebuild kit.
