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. If the throttle bodies or throttle cable malfunc- tions during operation, the T.O.R.S. will oper- ate when the throttle lever is released. The T.O.R.S. is designed to override the fuel injection and limit the engine speed to less than the clutch engagement speed if the throt- 8 WARNING
