A fluid metering device is provided including a chambered rotor for metering correctly proportioned mixtures of air and a vaporized fuel to an internal combustion engine. The rotor includes radially disposed chambers and is enclosed in a housing having an inlet port and an outlet port. Upon rotation of the rotor the chambers are alternately biased into flow communication with the inlet port and the outlet port. The inlet port is in flow communication with a gaseous fuel supply and the outlet is in flow communication with an intake to the internal combustion engine. The speed of the rotation of the rotor is adjustable to vary the amount of gaseous fuel presented to the engine for selectively varying the output of the engine.
