Coolant Level (5000)
NOTE: Use a good quality, ethylene
glycol-based, automotive-type coolant.
NOTE: Always check the coolant
level with the engine cold.
NOTE: The hood must be removed
for this procedure.
Locate the FULL COLD mark on the
coolant reservoir (located in the forward
engine compartment below the hood
hinge bracket).
If the coolant is below the FULL COLD
mark, add coolant to the reservoir until at
the FULL COLD mark.
Adjusting/Calibrating
Carburetors (2000)
0745-141
The carburetors have been adjusted/cali-
brated at the factory for average riding
conditions; however, altitude, tempera-
ture, and general wear may necessitate
certain carburetor adjustments.
Carburetor adjustments critically affect
engine performance; therefore, the fol-
lowing three external adjustments and
two internal calibrations can be made on
each carburetor.
NOTE: The following external car-
buretor adjustments may be done by
the snowmobile owner if qualified to
do so. If the owner does not feel
qualified, take the snowmobile to an
authorized Arctic Cat Snowmobile
dealer for this service. This service
is at the discretion and expense of
the snowmobile owner.
Adjusting Choke Cable
(External)
1. Be sure the ignition switch key is in
the OFF position and the brake lever
lock is set.
2. Slide the insulators away from the
adjusters; then loosen the jam nut
securing each choke cable adjuster.
Rotate each choke cable adjuster
clockwise until free-play is noted in
the choke lever.
3. Slowly rotate one choke cable
adjuster
counterclockwise
while
checking the choke lever for free-
play. As soon as all free-play has
been removed from the end of the
lever, stop rotating the adjuster.
4. With free-play removed from the lever,
slowly rotate each choke cable adjuster
once again clockwise while checking
the choke cable lever for free-play.
Adjust until 3 mm (1/8 in.) free-play
between front bottom edge of lever and
housing is attained. Securely tighten
the adjuster jam nut; then slide the
insulators onto the adjusters.
CAUTION
If the coolant is below the FULL
COLD mark and if coolant has been
added, immediately inspect for leak-
age and/or damage. If leakage or
damage is detected, take the snow-
mobile to an authorized Arctic Cat
Snowmobile dealer for service. If not
under warranty, this service is at the
discretion and expense of the snow-
mobile owner.
CAUTION
For information on altitude operation,
see Varying Altitude Operation sub-
section in the Operating Instructions
section.
CAUTION
Make sure to perform these adjust-
ment/calibration procedures on both
carburetors.
