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.
When installing the spark plug, be sure
to tighten it securely. A new spark plug
should be tightened 1/2 turn once the
washer contacts the cylinder head. A
used spark plug should be tightened 1/8
-1/4 turn once the washer contacts the
cylinder head.

take the ATV to an authorized KYMCO
ATV dealer.

side of the carburetor.
Start the engine and warm it up to
normal operating temperature.
