Throttle lever

Once the engine is running cleanly, squeez-
ing the throttle lever will increase the engine
speed and cause engagement of the drive
train. Regulate the speed of the snowmobile
by varying the throttle position. Because the
throttle is spring-loaded, the snowmobile will
decelerate, and the engine will return to idle
when it is released.
