摘要： There is provided a carburetor having a main air passageway extending between an air inlet and an air outlet and having a narrower venturi portion intermediate the air inlet and air outlet, a throttle valve being located near the air outlet, and a second narrower passageway extending substantially parallel to the main air passageway, the second narrower passageway having an air inlet from the main air passageway, a fuel inlet to the second passageway downstream from the inlet, and a first outlet from the second passageway to the main air passageway proximate the venturi portion and a second outlet from the second passageway intermediate the venturi portion and a throttle valve, the main air passageway having a flange extending inwardly from said wall at a downstream end of the venturi portion. The carburetor provides better fuel economy and efficiency.
