observe spark jumping at a predetermined gap
of 7 to 8 mm (.276 to .311 in).
If there is no spark, if it is weak or intermittent, the
coil is defective and should be replaced.

WARNING
Always reconnect spark plug cable to its orig-
inal spark plug. The cable coming out the
edge of the electrical box must be connect-
ed to the MAG side spark plug. Otherwise,
severe backfire may occur with possible
damage to exhaust system components.
The white tape on the ignition coil should
match the white tape on the high tension
cable.

IGNITION TIMING
General
Before checking ignition timing setting with a stro-
boscopic timing light (dynamic test), it is manda-
tory to scribe a timing mark on the PTO flywheel
(static test) corresponding to the engine specifica-
tion.
CAUTION: The relation between the PTO fly-
wheel mark position and crankshaft position
may change as the PTO flywheel might move
on crankshaft when engine is ran. This will
result in a false ignition timing reading. Al-
ways verify PTO flywheel mark position before
checking ignition timing with an appropriate
timing light. If mark does not align with tool,
repeat static test to ensure flywheel has not
moved before changing the ignition timing.
Normally, ignition timing setting should not be re-
quired. It has been set at factory and it should re-
main correctly set since every part is fixed and not
adjustable. The only time the ignition timing set-
ting might have to be changed would be when re-
placing the crankshaft, the magneto rotor, the CPS
or the MPEM. If the ignition timing setting is found
to be incorrect, you should first check for proper
crankshaft alignment. This might be the indication
of a twisted crankshaft.
