NOTE: Carburetor adjustments
and calibration 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 Snowmo-
bile dealer for this service. This
service is at the discretion and
expense of the snowmobile owner.
CAUTION
Make sure to perform these adjust-
ment/synchronization procedures
on all carburetors.
Adjusting Choke Cable
1. Be sure the ignition switch key is
in the OFF position and the brake
lever lock is set.
2. Loosen the jam nut securing each
choke cable adjuster. Rotate each
choke cable adjuster clockwise
until it bottoms against the brass
plunger cap.
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 clock-
wise 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.
NOTE: If a carburetor choke
cable is adjusted too tight when
the engine reaches operating tem-
perature, the air/fuel mixture will
be incorrect and the engine will
idle poorly and may operate only
on one cylinder.
Synchronizing Piston
Valves
1. Remove the air-intake silencer
boots from the silencer to access
the intake bores.
2. Rotate the idle speed screws coun-
terclockwise until all spring ten-
