Engine Idle Rpm Adjustment; Throttle Cable Adjustment; Air Filter - Arctic Cat 150 2013 Operator's Manual

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 0.6 mm (0.024 in.)
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 cyl-
inder head. A used spark plug should
be tightened 1/8-1/4 turn once the
washer contacts the cylinder head.

Engine Idle RPM Adjustment

To properly adjust the idle, a tachometer is necessary. If one is not
available, take the ATV to an authorized Arctic Cat ATV dealer.
1. To adjust idle RPM, start the
engine and warm it up to nor-
mal operating temperature.
2. Turn the idle adjustment screw
in or out until the engine idles
at 1700 RPM.
! WARNING
Adjust the idle to the correct RPM. Make sure the engine is at
normal operating temperature before adjusting the idle RPM.

mately 6 mm (1/4 in.) free-
play in the cable.

Air Filter

The air filter inside the air filter housing must be kept clean to provide
good engine power and gas mileage. If the ATV is used under normal
conditions, service the filter at the intervals specified. If operated in
dusty, wet, or muddy conditions, inspect and service the filter more
frequently. Use the following procedure to remove the filter and
inspect and/or clean it.
