Spark Plug
This vehicle comes equipped with a spec-
ified spark plug. See the specifications
chart for the correct spark plug. A light
brown insulator indicates that the plug is
correct. A white or dark insulator indi-
cates that the engine may need to be ser-
viced. Consult an authorized dealer if the
plug insulator is not a light brown color.
To help prevent cold weather fouling,
make sure to thoroughly warm up the
engine before operating.
To maintain a hot, strong spark, keep the
plug free of carbon.

Before removing the spark plug, be sure
to clean the area around the spark plug. If
you do not, dirt could enter engine when
removing or installing the spark plug.
Adjust the gap (see specifications chart)
for proper ignition. Use a feeler gauge to
check the gap.

A new spark plug should be tightened 1/2
turn once the washer contacts the cylin-
der head. A used spark plug should be
tightened 1/8 - 1/4 turn once the washer
contacts the cylinder head.
