An improved carburetor arrangement comprises a low-capacity fuel / air regulator for efficiently vaporizing rich mixtures of fuel and delivering them to a heat exchange vaporizer for heating and completely vaporized the rich mixture prior to delivery to an engine intake. An existing conventional fuel atomization system is eliminated and replaced with main combustion air gallery. The air gallery forms a low pressure for drawing heated rich mixture from the vaporizer and subsequently mixing it with a larger amount of incoming fresh air from t he gallery for forming a stoichiometric mixture. Preferably the mixture is pass ed through a mixing chamber before delivery to the engine intake. Preferably th e fuel / air regulator is a low-capacity carburetor, such as that used for motorcycles, snowmobiles and the like.
