This patent describes a centrifugal governor for use with an internal combustion engine, comprising: a control rack for regulating the quantity of fuel to be supplied to the engine; flyweights radially displaceable in response to the rotational speed of the engine; a tension lever pivotable through an angle dependent upon the amount of radial displacement of the flyweights; a torque cam pivotable about and relative to a fulcrum shaft thereof and having a cam surface including a cam surface portion determining a fuel increment to be applied at the start of the engine; a sensor lever having one end engaged by the control rack; the sensor lever having another end disposed to engage with the cam surface portion of the torque cam when the engine is in a starting condition, to permit displacement of the control rack into a fuel increasing position for the start of the engine; and a cancelling spring interposed between the torque cam and the tension lever and urging the torque cam with a force dependent upon the angularity of the tension lever to cause pivoting of the torque cam about the fulcrum shaft thereof in a direction of disengaging the sensor lever from the cam surface portion of the torque cam. The improvement is described comprising biasing means for forcibly pivotally displacing, immediately before operation of a starter of the engine, the torque cam in one direction against the urging force of the cancelling spring to a predetermined position.
