Abstract: An improved carburetor (10) is disclosed and claimed by this application. The carburetor (10) includes an updraft section (16), a crossdraft section (18), and a downdraft section (20). The updraft section (16) includes a mixing chamber (22) in which fuel and air are mixed. This mixture formed therein passes into a plenum (84) of the crossdraft section (18) through which a plurality of ducts (88) extend. A hot fluid passes through these ducts (88) to heat the mixture passing through the plenum (84). The mixture, thereafter, passes through a plenum outlet (86) into another plenum (104) of the downdraft section (20) and to an intake manifold (12) for distributing the mixture to the cylinders of the engine.
