Engine Maintenance
Checking the Spark Plug
DO NOT check for spark with spark plug removed. DO NOT crank engine
with spark plug removed.
If the engine has been running, the muffler will be very hot. Be careful not
to touch the muffler.
The spark plug must be securely tightened. An improperly tightened spark
plug can become very hot and may damage the engine.
To ensure proper engine operation, the spark plug must be properly gapped and
free of deposits. Check the spark plug every 25 hours and replace it every 100 hours.
