A throttle pedal assembly comprises a base, a pedal pivotably mounted on the base, and a gear box coupled to the pedal. The gear box has a throttle wheel with a plurality of throttle cable terminal attachment locations and the gear box has a plurality of throttle cable mounting locations. A throttle cable is selectively and releasably attached to one of said plurality of throttle cable terminal attachment locations, and the throttle cable is selectively and releasably attached to one of said plurality of throttle cable mounting locations.

A two-stroke combustion engine comprising a user-operated throttle control, an adjustable valve arranged to control one or more air intakes of the combustion engine, and a control unit arranged to control a state of the adjustable valve, wherein the combustion engine is arranged to operate in a first idle mode at an idle engine speed below a clutch engagement engine speed when the user-operated throttle control is not engaged, wherein the combustion engine is arranged to operate in a second idle mode at a target engine speed above the clutch engagement engine speed when the user-operated throttle control is engaged and when the engine is not subject to an external load, the control unit being arranged to control the state of the adjustable valve to maintain engine speed at the target engine speed when the engine operates in the second idle mode.

An engine operating device of a working machine includes a control assembly installed in a body, an operating lever mounted on a handle, and an operating cable. The control assembly includes a base member, a stop switch secured to the base member, and a lever member supported by the base member. The operating cable includes a throttle wire, a stop wire, and a cable tube in which the throttle wire and the stop wire are fitted. As the operating lever is moved to an engine stop position, the lever member moves to a release position, causing an engine to stop.

An engine having a linkage assembly, the linkage assembly having a governor lever, a governor shaft, and a throttle link. The governor lever couples the governor shaft to the throttle link. The governor lever is configured to adjust the relative position between the throttle link and the governor shaft. The governor lever has a primary arm and a secondary arm, the primary arm being movable with respect to the secondary arm. The primary arm and secondary arm are secured via a fastener which prevents relative motion between the primary and secondary arms.

An automatic aircraft powerplant control system includes a throttle servo for adjusting a throttle valve via a throttle control linkage. A throttle control lever provides a user input to the throttle servo, and a throttle controller controls the throttle servo for controlling a throttle valve. A dual-redundant propellor servo drive provides propellor control, and a dual-redundant mixture servo drive controls an air-fuel mixture. A first processor and a second processor are communicatively coupled with the dual-redundant propellor servo drive and the dual-redundant mixture servo drive and with each other to provide dual-redundant propellor and mixture control. The throttle control lever provides a single lever for pilot control of aircraft power, and the throttle control configuration is compatible with an auto-land capability.
