 NOTE: There must be free-play
in the throttle lever on all models.
! WARNING
Be sure to tighten the swivel
adapter jam nuts securely. If a
swivel adapter jam nut is not tight-
ened, the adjuster can rotate out of
the carburetor cap causing the pis-
ton valve not to return to the full-
closed position.
7. In turn on each carburetor, place a
finger against the piston valve.
Rotate the idle speed screw clock-
wise until it contacts the valve.
8. Compress the throttle lever to the
full-open position; then rotate each
idle speed screw clockwise 2 com-
plete turns. Release the throttle lever.
 NOTE: There must be 0.75-1.5
mm (0.030-0.060
between the throttle lever and the
control housing.
9. At this point, there must be 0.75-
1.5 mm (0.030-0.060 in.) of cable
free-play gap in the throttle lever.
If there is no cable free-play in the
throttle lever, the throttle safety
switches will not function prop-
erly, and the engine will cut out in
the idle position.

 NOTE: If cable free-play gap is
not correct, rotate each swivel
adapter an equal amount until rec-
ommended free-play is achieved.
Each piston valve must be resting
against the tip of its idle speed
screw.
 NOTE: If throttle cable free-play
is incorrect, the carburetor safety
switches will be activated prema-
turely and the engine will not start.
Fine-Tuning Pilot Air
Screws and Idle Speed
Screws
1. While counting the rotations, care-
fully rotate the pilot air screws
clockwise until lightly seated.
CAUTION
Do not force a pilot air screw when
rotating it clockwise; damage to
the pilot air screw needle tip will
result.
2. Rotate the pilot air screws counter-
clockwise the exact number of
rotations ± 1/4 turn from the seated
position as an initial setting.
3. Install the air-intake silencer boots
taking care that the boots are prop-
erly positioned and that the boots
are not "folded" in the air-intake
silencer causing a restriction of air
flow.
4. With the
shielded safety stand, start the
engine, release the brake lever
lock, and thoroughly warm up.
! WARNING
DO NOT stand behind the snowmo-
bile or near the rotating track.
