Abstract

A carburetor control system includes: a governor device that is coupled to a throttle lever, opens a throttle valve when an operation of an engine is stopped, and opens or closes the throttle valve in accordance with a rotational number of the engine when the engine is in operation; a choke return spring urging a choke lever in a direction to close a choke valve; and an automatic choke device opening the choke valve in accordance with an increase in temperature of the engine. In the carburetor control system, the throttle lever is provided with a drive arm pivoting the choke lever, during a cold operation of the engine, to a position where the choke valve is at an intermediate degree of opening in operative connection with the throttle lever being pivoted by the governor device to a position where the throttle valve is at a degree of opening for idling or a position in a vicinity thereof. Accordingly, it is possible to mechanically open the choke valve to a predetermined intermediate degree of opening, when the engine is in a cold idling state, in operative connection with the throttle valve, so as to be capable of ensuring a fuel-efficient and stable idling state.
