ABSTRACT:
A carburetor valve control system for stabilizing engine warm-up operating conditions by automatically controlling the degree of opening of a throttle valve so as to be larger than a normal degree of opening for idling, without carrying out a special operation of appropriately strengthening the spring force of a governor spring. The carburetor throttle valve control system includes a throttle lever and a governor system coupled to the throttle lever. A choke return spring is connected to a choke lever, the choke return spring urging the choke lever to a choke valve closing side. An automatic choke system is disposed so as to face the choke lever. A throttle valve closure restricting member is provided between the throttle lever and the choke lever. During engine warming-up, when the spring force of a governor spring is adjusted to zero or a minimum, the choke lever restricts closing of the throttle valve via the throttle lever by means of the spring force of the choke return spring.
