ENGINE MAINTENANCE
THROTTLE LEVER FREEPLAY
INSPECTION
Throttle lever freeplay is the gap between the throttle
lever and throttle block when the operator pushes the
throttle lever. The gap is present until the throttle cable
opens the throttle body plates. Excessive freeplay in the
throttle cable may cause the throttle release switch to
activate, potentially stalling the engine or preventing the
engine from starting.
WARNING
Do not operate the snowmobile if throttle cable freeplay
is too tight.
1. Stop the engine.
2. Slightly push the throttle lever until you feel the cable
tension increase (throttle plates opening).
3. Insert the blade of a feeler gauge between the throttle
lever and throttle block and compare to specification.

MEASUREMENT
Throttle Lever Freeplay:
.009 - .029 in (0.25 - 0.76 mm)
4. Adjust freeplay if the gap does not meet specification.

.
3. Rotate the adjuster clockwise to DECREASE
freeplay. Rotate the adjuster counter-clockwise to
INCREASE freeplay.
4. When freeplay is adjusted to specification, tighten the
lock nut against the adjuster.
MEASUREMENT
Throttle Lever Freeplay:
.009 - .029 in (0.25 - 0.76 mm)
5. Position protective sheath over the in-line adjuster.
6. Start the engine and allow it to idle.
7. Turn the handlebar to the full left and full right
positions. Verify that engine RPM does not increase
as the handlebar is turned. If engine RPM increases,
the throttle lever freeplay is too tight and must be
readjusted.
