ADJUSTING CARBURETORS —
TM-STYLE
The carburetors have been cali-
brated at the factory for average
riding conditions; however, alti-
tude, temperature, and general wear
may necessitate certain carburetor
adjustments. Be sure the correct
carburetor main jets for the oper-
ating temperature, altitude, and
type of gasoline are being used
(see Selecting Carburetor Main
Jet(s) section). Since carburetor
adjustments critically affect engine
performance, Arctic Cat recom-
mends that all changes in internal
carburetor calibration be made by an
authorized Arctic Cat Snowmobile
dealer; however, four external
adjustments can be made on each
carburetor. These are the choke
cable travel, fuel mixture screws, air
screws, and idle speed screw.

NOTE: Carburetor adjustments
and changing main jets 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 Arc-
tic Cat Snowmobile dealer for this
service. This service is at the dis-
cretion and expense of the snow-
mobile owner.
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 on
the side of the carburetor.

3. Slowly rotate one choke cable
adjuster 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 the
adjuster once ag ain while
checking the choke lever for
free-play. Adjust until 3 mm (1/
8 in.) free-play between front
bottom edge of lever and hous-
ing is attained. Securely tighten
the jam nut.
