Abstract
PURPOSE: To reduce impact force to bring a throttle valve into contact with cam surface by forming a cam surface of a first idle mechanism to control a throttle valve of a carburetor at the time of cooling off.
CONSTITUTION: A choke valve 4 is interlocked through a rod 17 and a cam surface 15A of a first idle cam 15 to a throttle valve 6. The choke valve 4 is linked with a bimetal 7, a diaphragm device 10 to open the choke valve to a certain opening degree after perfect explosion of the engine, and a heating element 22, the choke valve 4 opens with the rise of temperature. At the same time, the throttle valve 6 closes from first opening degree to idle opening degree. And the cam surface 15A of the first idle cam 15 is formed by are composed of radius R1WRm from the position P brought into an eccentricity out of the core O of its axis 14, gradual contact of a screw 18 of the throttle valve with the cam surface 15A is done more smoothly than the conventional one, to weaken its impact force.
