To ensure proper engine operation,
the spark plug must be properly
gapped and free of deposits.
The spark plug becomes very hot
during operation and will remain
hot for a while after stopping the
engine. Allow the engine to cool
before servicing the spark plug.
Check-clean/Replace interval:
Every 100 operating hours or 6
months.
Recommended spark plug:

Use only the recommended spark
plugs or equivalent. Spark plugs
which have an improper heat range
may cause engine damage.
See page 89 for instructions of
handling the Iridium spark plugs
(optional parts).
