PURPOSE: To try sure operation, by drive a choke lever to drive a choke valve and a throttle valve simultaneously due to wax element to operate receiving the required temperature from the engine under warming up condition.
CONSTITUTION: When the water temperature lowers, an operating shaft 27 of wax element 22 is pulled, the choke lover 21 is rotated counterclockwise, to choke valve 1 is shut. Simultaneously the throttle valve 9 is opened to the required opening corresponded to the water temperature for starting, the engine is easily started. After starting, when the water temperature is raised gradually, the operating shaft 27 pushes the lower arm of choke lever 21 to open the choke valve 1 to the opening corresponded to the water temperature, simultaneously since a cam 21b moves to the left, the throttle valve 9 is shut to the first idle opening corresponded to the water temperature, over running of the engine will be suppressed. Consequently sure operation may be obtained.
