Abstract
A starting apparatus of a diaphragm-type carburetor, a starting pump disposed at a convenient and accessible location which is separate from a carburetor main body, and air is prevented from being mixed into fuel, in such a structure constructed as a suction-type starting pump. A suction passage extends from a fuel metering chamber and extends beyond an outer portion of the carburetor main body. A starting pump conveniently disposed is separate from the carburetor, and an inlet check valve of the starting pump is disposed in the carburetor main body so as to reduce a volumetric capacity of a section extending to the inlet check valve from the fuel metering chamber, thereby preventing the air from remaining within the suction passage.
