Abstract
In a throttle device for a multipurpose internal combustion engine having a throttle valve connected to an electric motor and a carburetor, when an instruction to stop the engine is inputted, the electric motor is controlled to move the throttle valve in a fully closed position so as to stop the engine, and then to move the throttle valve in a fully opened direction. With this, throttle valve can be surely opened to facilitate restarting, and the occurrence of dieseling and run-on is prevented without providing a fuel cut valve to the carburetor. Further, a spring is provided to urge the throttle valve in an opening direction. With this, the response in opening the throttle valve is enhanced and the size of the motor is reduced.
