8. MAINTENANCE - continued
2.
Use a spark plug wrench to remove the spark plug.
3.
Inspect the plug; replace it if the electrode is worn, or if the insulator is
cracked or chipped.
4.
If you are going to reuse the spark plug, remove carbon deposits with a stiff
wire brush.
5.
Measure the spark plug gap with a suitable gauge. The gap should be 0.7-
0.8mm. Correct the gap, if necessary by bending the side electrode.
6.
Install the spark plug carefully by hand, to avoid cross-threading.
7.
After the spark plug seats, tighten with a spark plug wrench to compress
the washer.
If reinstalling the old spark plug, tighten ⅛ to ¼ turn after the spark plug
seats.
If installing a new spark plug, tighten ½ turn after the spark plug seats.
NOTICE
A loose spark plug can overheat and damage the engine.
Over tightening the spark plug can damage the threads in the cylinder
head.
8.
Install the spark plug cap on the spark plug.
