Check the spark plug gap using a wire-
type feeler gauge.
u
If adjustment is necessary, bend the
side electrode carefully.
The gap should be:
0.80 - 0.90 mm (0.031 - 0.035 in)
7.
Make sure the plug washer is in good
condition.
8. Install the spark plug. With the plug washer
attached, thread the spark plug in by hand to
prevent cross-threading.
9. Tighten the spark plug:
●
If the old plug is good:
1/8 turn after it seats.
●
If installing a new plug, tighten it twice to
prevent loosening:
a) First, tighten the plug:
1/2 turn after it seats.
b) Then loosen the plug.
c) Next, tighten the plug again:
1/8 turn after it seats.
NOTICE
An improperly tightened spark plug can damage the
engine. If a plug is too loose, a piston may be
damaged. If a plug is too tight, the threads may be
damaged.
10. Install the parts in the reverse order of
removal.
u
When reinstalling the spark plug cap,
take care to avoid pinching any cables
or wires.
