When installing the spark plug, be sure to tighten it securely. A
new spark plug should be tightened 1/2 turn once the washer con-
tacts the cylinder 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.
To adjust idle RPM:
1. Start the engine and warm it
up to normal operating tem-
perature.
2. Turn the idle adjustment
screw in or out until the
engine idles at 1700 RPM.
THROTTLE CABLE ADJUSTMENT
The throttle has been adjusted
at the factory, and no adjust-
ment should be necessary. If
adjustment is necessary, the fol-
lowing procedure should be
followed:
1. Pull back rubber boots to
access cable adjustment
nut.
2. Loosen jam nut to allow
cable adjustment nut to be
adjusted.
3. Turn cable adjustment nut
clockwise to increase free-
play in the cable. Turn the
adjustment nut counter-
clockwise to decrease free-
play in the cable.
4. There should be approximately 6 mm (1/4 in.) free-play in
the cable.
5. Tighten the jam nut to secure the adjustment.
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 speci-
fied. 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.
1. Remove the seat; then
remove the five screws secur-
ing the air filter housing
cover.
2. Remove the air filter housing
cover; then pull the filter out.
! WARNING
Adjust the idle to the correct RPM. Make sure the engine is at
normal operating temperature before adjusting the idle RPM.
