Idle Switch

The idle switch, located on the throttle valve housing, is operated by a lever on the throttle valve shaft. It performs 3 functions:

• When the throttle is closed, if idle speed drops below 820 RPM, the idle stabilizer function in the control unit is switched on.
• When engine speed is above 1000 RPM, the idle switch activates the deceleration control function in the control unit upon deceleration.
• When the throttle valve is opened, the control system for determining ignition timing is switched on.
