A vehicle has a combustion engine, ground-engaging drive wheels, a power transmission for conveying power from the engine to the wheels, an induction passage for supplying motive fluid to the engine, a source of fuel, adaptive structure defining a fuel metering system communicating generally between the source of fuel and the induction passage, the adaptive structure having a valving arrangement in the fuel metering system effective to controllably alter the rate of metered fuel flow through the fuel metering system, and a manually controlled adjustment operatively connected to the valving arrangement, the manually controlled adjustment being effective to selectively control the valving arrangement in order to thereby selectively alter the rate of metered fuel flow to the engine.
