ABSTRACT:
A two-cycle air-cooled engine has a carburetor with a throttle valve operated by a manual control member. A heat sensitive valve mounted on the engine cylinder head closes to cut off a supplementary air supply to the induction passageway and thereby richen the air-fuel mixture to prevent seizure upon overheating. When the manual control member is in position corresponding to idling of the engine, the member actuates means which introduce additional air into the induction passageway leading to the engine, to lean the air-fuel mixture.
