ELECTRICAL ADJUSTMENTS
2. Disconnect the two blue wires from the
external ignition coil primary.
3. Connect one lead of the ohmmeter or timing
buzzer to engine ground, and the other lead
to the end piece holding the two blue wires,
Fig. IV-50.

4. Rotate the flywheel clockwise until the
timing mark on the inner sheave of t he rope
pulley lines up with the M mark on the fan
housing, Fig. IV-50.
5. When the timing marks line up , the ohmmeter
is to show a positive deflection toward the
OPEN end of the scale, Fig. IV-50, or the
timing buzzer should shut off if it is being
used.
6. If t iming marks line up, ignition timing is
correct (proceed to step 11). I f the ohmmeter
needle showed a positive deflection toward
the OPEN end of the scale, or the buzzer
shut off before the timing marks lined up,
the timing is advanced and must be retarded
to correct the problem (see step 7 and 8). If
the ohmmeter needle showed a positive
deflection toward the OPEN end of the scale
or the buzzer shut off after the timing
mark~
lined up, the timing is retarded and must be
advanced to correct the problem (see step 9
and 10).
7. RETARD TIMING - Loosen the three
magneto base plate retaining screws, Fig.
IV-51, using a screwdriver having a 5/16-inch
IV-30
blade. Move the magneto base plate clockwise
to retard the tim ing, Fig. IV-51; then tighten
the three retaining screws. FLYWHEEL HAS
BEEN REMOVED FOR CLARITY
PURPOSES ONLY, BUT IT IS NOT
NECESSARY TO REMOVE THE
FLYWHEEL WHEN ADJUSTING THE BASE
PLATE.

8. Repeat steps 4-6 and recheck breaker point
gap until timing is correct.

Note: Breaker point gap will have an effect on
ignition timing. Opening the breaker point
gap advances the firing moment, and closing the
g~p .
retards the firing moment. Check ignition
tlmmg whenever breaker point gap is adjusted.
9. ADVANCE TIMING - Loosen the three
magneto base plate retaining screws, Fig.
IV-51, using a screwdriver having a 5/ 16-inch
b I a de. Move the magneto base plate
counterclockwise to advance the timing, Fig.
IV-51; then tighten the three retaining screws.
