Coinola tracker bars that play O rolls in original machines have 90
holes.  The end holes are not counted in the tracker scale as they are
the play and rewind holes.

The first hole on the right is a larger hole and that is the "Play" hole
to shift the transmission into the play or forward position.  These
holes are not counted in the scale.  The first small hole is number
one.   In original machines hole number 18 has an arrow above the hole
indicating that it is the coin trip hole.

If a machine is tubed correctly and the sustaining pedal still
functions when it is not supposed to, then there is a problem with the
sustaining pouch, valve, or bleed.  As the suction changes with the
different amount of notes being used, the pedal can act up if the bleed
is not correct or the pouch is getting a bit of air that it should not.

P.S.:  I need Coinola parts (and someday a Coinola Cupid to complete
my Coinola Collection).
