Abstract
Systems and apparatuses include an engine including a fuel tank, a carburetor including a throttle valve movable between a first throttle position and a second throttle position, a governor system configured to move the throttle valve, and a speed control system including a control lever defining a first actuation distance, and a bellcrank movable between an idle position and a high speed position and coupled to the governor system. The bellcrank defining a second actuation distance that is different than the first actuation distance.
Claims20
An engine comprising:
- a fuel tank;
- a carburetor including a throttle valve movable between a first throttle position and a second throttle position;
- a governor system configured to move the throttle valve;
- and
- a speed control system including
- a control lever movable between a first position and a second position, and defining a control lever coupling structure that defines a first actuation distance, and
- a bellcrank movable between an idle position and a high speed position, and defining a first bellcrank coupling structure and a second bellcrank coupling structure that defines a second actuation distance that is different than the first actuation distance, the bellcrank coupled to the governor system,
- wherein the speed control system is structured to be controlled by a remote actuator configured to engage one of the control lever coupling structure, the first bellcrank coupling structure, or the second bellcrank coupling structure to move the control lever and the bellcrank, and
- wherein the engine is structured to support the remote actuator to provide control from a first lever direction when the remote actuator engages the control lever coupling structure, a second lever direction opposed to the first lever direction when the remote actuator engages the control lever coupling structure, a first bellcrank direction when the remote actuator engages the first bellcrank coupling structure, a second bellcrank direction opposed to the first bellcrank direction when the remote actuator engages the first bellcrank coupling structure, and a third bellcrank direction different than the first bellcrank direction and the second bellcrank direction when the remote actuator engages the second bellcrank coupling structure.
