Servicing the Spark Plug
Service Interval:
Every 100 hours—Inspect, clean,
and adjust the spark plug gap;
replace the spark plug if necessary.
Use an
NGK BPR5ES
spark plug or equivalent.
1.
Shut off the engine and wait for all moving parts
to stop.
2.
Disconnect the wire from the spark plug.
3.
Clean around the spark plug.
4.
Remove the spark plug from the cylinder head.
Important:
Replace a cracked, fouled, or
dirty spark plug. Do not clean the electrodes
because grit entering the cylinder can
damage the engine.
5.
Set the gap on the plug to 0.76 mm (0.030 inch);
refer to
.

6.
Carefully install the spark plug by hand (to avoid
cross threading) until it is hand tight.
7.
Tighten the spark plug to 23 N∙m (2.3 kgf-m, 17
ft-lb).
Important:
A loose spark plug can become
very hot and can damage the engine;
overtightening a spark plug may damage the
threads in the cylinder head.
8.
Connect the wire to the spark plug.
