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.
