ABSTRACT:
An improved control apparatus includes an auto-choke for an engine provided by interlocking a choke lever and a throttle lever of a carburetor by way of a temperature-sensitive interlocking rod. The choke lever of the carburetor is provided with a spring for resiliently biasing the choke valve toward its open position. The interlocking rod is made of high molecular material such as high molecular urethane elastomer or the like and has a buckling threshold which varies in dependence upon the temperature. Upon fully opening the throttle valve when the engine is cold, the interlocking rod acts so as to close the choke. Whereas, when the throttle valve is opened when the engine is hot the interlocking rod acts to open the choke under the biasing force of the spring. A speed regulating device is connected to the throttle lever.
