PERIODIC MAINTENANCE AND ADJUSTMENT
To install the spark plug
1. Measure the spark plug gap with
a wire thickness gauge and, if
necessary, adjust the gap to
specification.
Spark plug gap:
0.7 - 0.8 mm (0.028 - 0.031 in)
2. Clean the surface of the spark
plug gasket and its mating sur-
face, and then wipe off any grime
from the spark plug threads.
3. Install the spark plug with the
spark plug wrench, and then
tighten it to the specified torque.
Tightening torque:
Spark plug:
13 Nm (1.3 m·kgf, 9.4ft·lbf)
TIP
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is 1/4 -
1/2 turn past finger tight. However, the
spark plug should be tightened to the
specified torque as soon as possible.
4. Install the spark plug cap.
5. Install the panel.
