Magnetos are timed to the engine in the factory and retiming should not be necessary unless mag
-
neto has been removed for reconditioning.
Use the following procedure for initial timing of the stand
-
ard type magneto to the engine.
I.
Uncover timing sight hole on blower housing of engine. Turn engine over by hand until
DC
mark on flywheel is centered in sight hole.
2.
Turn magneto gear in clockwise direction (when facing gear end) until impulse coupling
trips
--
loud click will be heard. After coupling trips, back up slightly (turn in counterclock
-
wise direction) on gear until it drags lightly and remains in stationary position.
Refer to Figure

for relative position of slot in gear to grounding stud when timing
position is reached.
3.
Place new gasket on flange then while holding gear in timing position attained in Step 2,
carefully guide magneto gear into engagement with cam gear.
4.
After securing magneto to housing, test by turning flywheel in clockwise direction until
impulse coupling trips (loud click)
--
DC mark on flywheel should be just past center mark
in sight hole.

INSTALLING
AND
TIMING MAGNETO TO ENGINE
Use timing light to time ignition after installation.
Under no circumstances should battery be
hooked up to a magneto as this will
severly damage coil windings.
With timing light properly hooked
up (refer to timing light instructions), time ignition as follows:
1.
Start engine and run at
1200 RPM or above while timing.
2.
Aim timing light into sight hole. SP mark should be centered in the hole just as the light
flashes. To adjust, loosen the two capscrews on the flange then shift position of
magnetc
until SP mark is properly aligned in sight hole. Tighten capscrews after adjusting.
