IGNITION TIMING
NOTE
The spark unit system is factory pre-set and cannot be ad-
justed. Ignition timing inspection procedures are given to in-
spect the function of the spark unit components.
Connect the timing light to the other spark plug wire if you
see that the ignition timing is incorrect, and you might be
able to see the timing is correct.
Warm up the engine to operating temperature.
-'-----------
If the engine must be running to do some work, make sure the
area is well-ventilated. Never run the engine in an. enclosed
area.
The exhaust contains poisonous carbon monoxide gas that may
cause loss of consciousness and lead to death.
Remove the timing inspection hole cap on the left crankcase
cover.
Connect the timing light to the front spark plug wire.
The timing is correct if the "F" mark aligns with the index
mark on the right crankcase cover at idle for each cylinder.
Raise the engine rpm and the "F" mark should begin to rotate
counterclockwise for each cylinder.
If the ignition timing is incorrect, make a ignition system in-
spection (page 1 6-3) and replace any faulty parts.
