7.
Install the spark plugs. With the plug
washers attached, thread the spark plugs
in by hand to prevent cross-threading.
8.
Tighten each 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:
2/3 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.
9.
Install the parts in the reverse order of
removal.

When reinstalling the spark plug caps,
take care to avoid pinching any cables
or wires.
