Carburetor air-fuel mixtures are directed to a manifold having a plurality of long, small diameter helical tubes extending upwardly therefrom. An auxiliary air inlet having an auxiliary choke and an auxiliary air throttle supplies air to mixtures entering the tubes in response to engine temperature and carburetor throttle. Heated engine coolant flows upwardly through a jacket enclosing the tubes. An outlet manifold receives air-fuel mixtures vaporized in the tubes and directs them to the engine intake manifold. The carburetor is mounted on a block having an air-fuel passageway extending from a top inlet to a side outlet. The block is mounted atop a block having a passageway having a side inlet which receives vaporized air-fuel mixtures from the tubes to a bottom outlet in communication with the intake manifold.
