A worn outhole on a Gottlieb EM can cause a really annoying problem where
the ball drops in the outhole but doesn't get properly seated on the kicker
arm. The arm tries to fire the ball to the plunger but the ball keeps
banging the underside of the card holder and drops back into the worn area
of the outhole again and again. An easy fix is to take an old switch blade
and cut it down to a couple inches or so, including the end with the two
large mounting holes. Remove the card holder and uncrew the single wood
screw holding the ball trough at the outhole end. Bend the end of the
switch blade at a 45 degree angle, and slide the blade between the playfield
and the ball trough, lining up a mounting hole with the ball trough screw
hole. The bent end of the blade should be pointing down into the right side
of the outhole. Trim and bend as needed to be sure the blade doesn't
interfere with the kicker arm or the outhole switch. Replace and tighten
the ball trough screw and the !
problem is fixed.
