Servicing the Spark Plug

Service Interval: Every 200 hours—Check, clean and
regap the spark plug.
Make sure the air gap between the center and side
electrodes is correct before installing the spark plug.
Use a spark plug wrench for removing and installing

Checking the Spark Plug
Important: Replace the spark plug(s) when it has:
a black coating, worn electrodes, an oily film, cracks
or reuse is questionable.
If you see light brown or gray on the insulator, the
engine is operating properly. A black coating on the
insulator usually means the air cleaner is dirty.
