CAUTION: If engine is to be run more than a
few seconds, engine must be cooled using the
flush kit.
– Check if PTO flywheel mark aligns with timing
tool slot.
NOTE: On this system, timing advance decreases
as engine speed increases.
If timing mark aligns with tool slot, timing is prop-
erly set. If mark does not align with tool slot,
recheck PTO flywheel mark (static test) before ad-
justing ignition timing to ensure PTO flywheel has
not loosen or tightened.
Ignition Timing Adjustment
Remove magneto housing cover and wire sup-
port. Refer to MAGNETO SYSTEM.
Timing is performed by moving armature plate;
clockwise to retard spark occurrence or counter-
clockwise to advance.
