1. Rotate the flywheel clockwise until the
timing mark on the inner sheave of the rope
pulley lines up with the T mark on the fan
housing.
2. Adjust the breaker point gap to 0 .014-0 .018
inch, using a feeler gauge and screwdriver
having a 5/16-inch blade. Feeler gauge and
screwdriver can be inserted through the holes
in the flywheel.

4. Recheck the breaker point gap and adjust if it
is necessary .
II Note: Due to the wear-in characteristic of the
breaker point "lifter", Fig. IV -49, the points
are to be adjusted nearer 0.018 inch, rather than
0.014 inch.

Note: Breaker point gap will have an effect on
ignition timing. Opening the breaker point
gap advances the firing moment, and closing the
gap retards the firing moment. Check ignition
timing whenever breaker point gap is adjusted.
5. Adjust the ignition timing
(see
Set Ignition
Timing, page IV-29).
