IGNITION TIMING ADJUSTMENT
TIMING PLATE POSITION ADJUSTMENT
If the timing plate is moved even a little dur-
ing inspection or repair operation, it should
be set in the following way:
This adjustment must be made before
adjusting the ignition timing.
1. Remove the spark plugs from the cylin-
ders.
2. Install a dial-gauge in the spark-plug
hole of No. 1 cylinder.
NOTE:
For easy timing-plate adjustment, it is
advisable to remove the spark plugs from
all the cylinders.
3. Slowly turn the flywheel CLOCKWISE,
and stop it when the piston is at TDC.
4. If the end of the timing plate is not
aligned with the TDC mark on the CDI
magneto rotor, loosen the timing plate
set screw, align the timing plate end
with the TDC mark, then tighten the
screw.
5. Remove the dial gauge from the No. 1
cylinder and install the spark plugs for
each cylinder.
NOTE:
After tightening the screw, paint over the
screw-head to discourage tampering with
the adjustment.
