TIMING ADJUSTMENTS
Engine is timed while cranking engine with starter
motor. To prevent engine from starting when
being cranked, all spark plugs must be removed,
except no. 1 (top) cylinder plug.
CAUTION
NOTE: If initial timing adjustments are made without
engine running, then final timing checks should be
made with engine running due to timing advance
characteristics of ignition system. Minimum engine
RPM required to check maximum timing advance is
3000 RPM.
IDLE TIMING ADJUSTMENT
1. Connect timing light to no. 1 (top) spark plug.
WARNING
Before cranking engine, keep clear of propeller as
it may rotate.
2. Shift engine to “Neutral”.
IMPORTANT: To accurately time engine at cranking
speed, a fully charged battery must be used.
3. Holding throttle arm at idle position, crank engine
with starter motor and adjust idle timing screw to
align 2
