1. An internal combustion engine kart comprising:
an engine comprising an air inlet flap;
an accelerator pedal;
an operating lever which is connected to rotate the air inlet flap to control an amount of air entering the engine;
an accelerator cable connecting the accelerator pedal and the operating lever;
a controller configured to receive at least one control signal emitted by a remote transmitter and comprising a movable stop positioned to control movement of said operating lever so as to change a range of movement of the operating lever and consequently a level of maximum opening of the air inlet flap, wherein movement of said movable stop is dependent on said control signal;
a compensation spring mounted in an extension of said accelerator cable, between the accelerator cable or a slider driven by said accelerator cable and the operating lever, said compensation spring acting in tension to lengthen gradually when said operating lever is in contact with said movable stop and a driver continues to press said accelerator pedal, so that ranges of movement of said accelerator pedal are identical regardless of a position of said stop.
