Claim 2
Dependent Claim

In combination: A carburetor main body including at least one nozzle discharging a directed jet of fuel; a carburetor throttle body including at least one throttle valve for controlling the flow of combustion air past said nozzle;
Claim 3
Dependent Claim
206 words
a heat exchanger having a conduit for liquid flow and plurality of spaced fins carried by said conduit in heat conducting relation thereto; housing means for mounting said heat exchanger between said main body and said throttle body so that fuel discharged by said nozzle flows over and between said fins before reaching said throttle valve; and means for connecting said conduit and said heat exchanger for circulation of a fluid therethrough; in which said housing means comprises a block of metal aperture to provide passage between said nozzle and said throttle valve, and in which the conduit of said heat exchanger extends transversely across said opening in a first direction, and said fins extend transversely there across in a second direction orthogonal with said first direction, and vary in a first dimension in accordance with their positions along said conduit, to agree with the transverse configuration of said passage means; and in which said fins extend beyond said housing means, in the direction of said passage means, towards said nozzle, and terminate somewhat within said housing means, in the direction of said passage means toward said throttle valve, so that in use said conduit is at a desired position between said nozzle and said throttle.
