SPARK PLUG SERVICE

In order to service the spark plug, you will need a spark plug wrench
(commercially available).
Recommended spark plug: BPR6ES (NGK)
Incorrect spark plugs can cause engine damage.
For good performance, the spark plug must be properly gapped and
free of deposits.
Allow the engine to cool before servicing the spark plug.
1. Disconnect the spark plug cap, and remove any dirt from around the
spark plug area.
2. Remove the spark plug with a 13/16-inch spark plug wrench.
