face, and then wipe off any grime
from the spark plug threads.

TIP
If a torque wrench is not available
when installing a spark plug, a good

1/2 turn past finger tight. However, the
spark plug should be tightened to the
specified torque as soon as possible.
3. Install the spark plug cap.

Install the spark plug cap so that it is
positioned as shown in the illustration
and the spark plug lead does not con-
tact any surrounding parts.
4. Install the panels.
