Abstract
A fuel supply passage leading to a fuel tank is connected to an intake side of a fuel pump of a diaphragm-type carburetor, and a fuel transfer chamber incorporated in an intermediate portion of the fuel supply passage is provided in an insulator interposed between the carburetor and an engine. The fuel pumped from the fuel tank is heated in the chamber moderately, thereby decreasing the difference in temperature between the carburetor and the fuel introduced into the carburetor. Thus, the generation of fuel vapor in the diaphragm-type carburetor can be restrained.
