Rebuild EM flippers before fitting stronger coils

Don't start with a hotter coil. Replace the sleeve, plunger and link, and playfield bushing first; only if power is still lacking go to high tap or a stronger coil. Flippers that can send the ball all the way up the playfield are generally strong enough. A little more travel also adds strength.
