ABSTRACT:
A control mechanism for a carburetor having a throttle valve and a choke valve each of which valves has an idling position, a cold-starting position and a full-speed position. The throttle valve is spring-biased towards its idling position and the choke valve is spring-biased towards it full-speed position. Control levers are associated with the respective valves whereby when the choke valve is moved from its idling position towards it full-speed position, a lever member associated with the choke valve engages another lever member associated with the throttle valve and the interengaging lever members hold both valves in their cold-starting position in opposition to the biasing springs. From the cold-starting condition the lever members can be released by operation of the throttle valve causing the choke valve to be returned to its open position by its biasing spring or alternatively the choke valve can be moved independently to its full-speed position by a further control lever while the lever members remain in engagement.
