1. Fuel limiting apparatus for an internal combustion engine operably connected to a transmission capable of being operated in a first gear and a second gear, the apparatus including throttle means through which fuel is supplied to the engine controlled by an accelerator, comprising:

  • a. means for limiting to a first value the maximum fuel flow rate through the throttle means called for by the accelerator to thereby reduce maximum power output of the engine to a first power output, wherein said first power output is less than an unrestricted power output of the engine resulting from an unrestricted fuel flow through the throttle;

    b. means for increasing to a second value the maximum fuel flow rate through the throttle means called for by the accelerator to thereby increase said maximum power output of the engine to a second power output, said second power output being greater than said first power output;

    c. wherein said first value limiting means reduces said maximum power output of the engine to said first power output when the transmission is being operated in the first gear; and

    d. wherein said second value increasing means increases the maximum power output of the engine to said second power output when the transmission is being operated in the second gear.
