Spark Plug
This snowmobile comes equipped with a
specified 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 indicates
that the engine may need to be serviced or
the carburetor may need to be adjusted.
Consult an authorized Arctic Cat Snowmo-
bile 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 to specified amount (see
specifications chart) for proper ignition.
Use a feeler gauge to check the gap.

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 cyl-
inder head.
Brake
Arctic Cat recommends that the complete
brake system be checked daily for wear
or damage and for smooth operation.
Periodically, the brake band should be
inspected for cracks and to ensure the
liner is intact and not worn excessively.
Replace the brake band if cracked or
worn excessively.
