Abstract
A fuel supply system for engines having a carburetor which has a float chamber and a vapor bleed passage connected to the float chamber, wherein a part of a fuel supply passage means for supplying fuel from a fuel tank to the carburetor traverses through the float chamber so that the fuel flowing through the fuel supply passage means absorbs heat from the fuel contained in the float chamber. The fuel entering into the float chamber releases volatile light components as vapor towards the vapor bleed passage while the liquid fuel contained in the float chamber becomes a more stable liquid due to the release of volatile components and the cooling effected by heat exchange with the fuel flowing through the fuel supply passage means.
