IGNITION TIMING (MAcsNET~) .
Timing Magneto Ignition: For precision timing,
use timing light per instructions furnished by the light
manufacturer. Do not connect a battery to the magneto as this will ruin the coil windings.
To time
ignition, proceed as follows:
1.
After making sure breaker point gap is properly set, connect timing light to #l cylinder then
start engine.
2.
3.
Aim timing light into.pointer area on bell housing.
SPK mark should be even with the pointer just
as the light flashes.
If it is not, proceed with Step 3.
To adjust timing, loosen (do not remove) the two magneto mounting capscrews-shift position of
magneto (top flange eccentric) until SPK mark is exactly centered.
After proper timing is
attained, retighten mounting capscrews.

remove distributor cap and check con-

Replace points if badly worn or pitted.

To adjust point gap. turn engine over until point
point gap should be set at . 020rf.
Check and adjust gap after servicing or
replacing points.
m Every 500 hours,
remove the plug on the distributor housing and the plug on the drive housing as
shown-fill reservoirs with SAE 20 weight oil.
Reinstall plugs after se&&g. Distributor rot&

STEP 3:
retiming becomes necessary,
To establish firing position of #I cylinder,
rotate engine by hand until timing mark on gen-
erator fan (SPK) Lines up with timing mark (Line) on generator housing and compression is
felt in #l cylinder (place thumb over spark plug hole).
With distributor removed from engine, remove distributor cap, rotor and cover. Reinstall
rotor and rotate drive gear until ignition points just begin to open when rotor is positioned
to fire #l spark plug,
.
Install distributor on engine. Reassemble cover,
rotor and cap in proper position.
Connect
spark plug leads as indicated, use timing light for precision timing of the ignition.
