Removing the Spark Plug
1. Park the machine on a level surface and disengage the PTO. Stop the engine, wait for all moving parts to stop,
and remove key. Engage the parking brake.
2. Disconnect the wire from the spark plug.
NOTE: Due to the deep recess around the spark plug, blowing out the cavity with compressed air is
usually the most effective method for cleaning. The spark plug is most accessible when the
blower housing is removed for cleaning.
