 SPARK PLUG

 Disconnect the spark plug cap and clean
 around the spark plug.
 Clean around the spark plug base with
   compressed air before removing, and be
   sure that no debris is allowed to enter the
   combustion chamber.




                                                    Spark Plug
 Remove the spark plug using a equipped
 spark plug wrench or an equivalent tool.
 Inspect or replace as described in the
 maintenance schedule.




 INSPECTION

 Remove the carbon deposits from the spark
 plug with a small wire brush or a spark plug
 cleaning machine.

 The spark plug should be replaced
 periodically. Whenever removing the
 carbon deposits, be sure to observe the
 operational color of the spark plug's
 porcelain tip. This color tells you whether or
 not the standard spark plug is suitable for
 your type of usage. A normal operating
 spark plug should be light brown or tan
 color. If the spark plug is very white or
 glazed appearing, then it has been operating
 much too hot. This spark plug should be
 replaced with the colder plug.

 Recommended spark plug: NGK: CR7E
