Final Engine Timing
CAUTION: REMOVE THE TIMING PIN FROM
THE MAGNETO BEFORE ROTATING THE
MAGNETO ROTOR
PROPELLER. FAILURE TO REMOVE THE
TIMING PIN FROM
DISTRIBUTOR BLOCK MAY DAMAGE THE
MAGNETO.
•
Attach a timing light to the magneto
condenser stud according to the timing light
manufacturer's instructions.
•
Rotate the magneto clockwise, until the
timing light indicates the breaker points are
open. Most timing lights indicate open
points with a light-on condition or an audible
signal.
•
Slowly rotate the magneto counter-clockwise
until the light goes out or the audible signal
stops.
•
If installing impulse coupling magneto, move
to front of engine and rotate crankshaft ring
gear to approximately
disengage impulse coupling and then slowly
rotate back to correct timing per engine data
plate. Adjust magneto accordingly for points
to close at proper time. Synchronize timing
of both magnetos.
•
If installing non-impulse coupling magneto,
move to front
crankshaft ring gear to timing per engine
dataplate. Adjust magneto accordingly for
points to close at proper time. Synchronize
timing of both magnetos.
Secure Magneto
•
Fasten the magneto to the engine by
tightening the magneto mounting clamps.
•
Alternately tighten the engine mounting
clamp nuts to 96 in-lb torque.
•
Continue to tighten both nuts in alternating
steps to 200 in-lb torque.
•
Remove the timing light from the magneto
condenser stud.
•
Re-install harness cap to magnetos.

condenser stud using the lock-washer and
nut on the magneto.
•
Tighten the P-lead terminal nut to 13-15 in-lb
torque.
•
Attach P-lead ground shield, if applicable, to
the ground screw on the side of the
magneto. Tighten the P-lead ground shield
screw to 18-20 in-lb torque.

Ignition Harness Replacement

•
Confirm that the harness or lead in question
is installed correctly. Refer to the Ignition
Wiring Diagram (Figure 72-00-02.10) and
the ignition harness arrangement as shown
in the engine rear views, Figures 72-00-02.5
and 72-00-02.9.
•
If an ignition harness or an individual lead
to needs to be replaced, do the following:
1) Identify the harness or lead for its
location on the magneto and/or spark
plug.
2) Remove the screws securing the clips
and clamps. Mark the location so the
replacement harness or individual leads,
clips, and clamps can be reinstalled in
the correct location.
NOTE: An attaching hardware kit is provided
with new replacement harnesses.
Install and route the harness or individual lead
and secure with clips, clamp, and other screws
or kit hardware
