Throttle lever
Once the engine is running cleanly, squeez-
ing the throttle lever will increase the engine
speed and cause engagement of the drive
system. Regulate the speed of the snowmo-
bile 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.
