ABSTRACT:
In a general-purpose internal combustion engine having a throttle valve and a choke valve each installed in an air intake passage connected to a combustion chamber, air sucked in flowing through the air intake passage and mixing with fuel supplied by a carburetor to generate an air-fuel mixture that enters the combustion chamber of a cylinder and is ignited to drive a piston to rotate a crankshaft to be connected to a load such as a generator, there are provided an electric motor (actuator), a throttle valve opening/closing mechanism connected to the motor to open/close the throttle valve and a choke valve opening/closing mechanism connected to the throttle valve opening/closing mechanism to open/close the choke valve in response to operation of the throttle valve opening/closing mechanism, thereby enabling to move a choke valve without need to install an additional actuator.
