Abstract: A throttle body assembly for a combustion engine includes a throttle body having a pressure chamber including a supply of liquid fuel, and a throttle bore with an inlet through which air is received. A throttle valve is carried by the throttle body with a valve head movable relative to the throttle bore. A metering valve is coupled to the throttle body, and has a valve element that is movable between open and closed positions. A boost venturi is located in the throttle bore and has an inner passage that is open at both ends to the throttle bore. The boost venturi has an opening through which fuel flows into the inner passage when the valve element is in the open position, wherein fuel flows from the pressure chamber to the metering valve under the force of gravity or under a pressure of less than 6 psi.

Abstract: An engine control and input system for a device having a tool driven by an engine, includes an input and control module having one or more inputs and a controller responsive to actuation of the inputs to permit user control of at least one engine operating parameter by user actuation of the inputs. The system may include a touch screen display that displays icons to the user relating to the inputs and the at least one engine operating parameter, and wherein the touch screen display is responsive to the user selecting one of the inputs by touching an associated one of the icons provided by the display. At least one of the inputs may relate to one or more of changing engine speed, starting the engine, causing the engine to drive the tool, turning on a light, actuating a heater or warmer or stopping engine operation.

Abstract: In at least some implementations, an ignition system for a combustion engine includes a controller, an ignition circuit, and a wire providing two-way communication between the ignition circuit and the controller. The ignition circuit may include a charge capacitor that is discharged to cause an ignition event. The ignition circuit may be an inductive discharge ignition circuit including a coil and may then also include a second wire that provides electrical power to the coil.

Abstract: An assembly for an engine includes a control module including a controller operable to control at least certain aspects of the operation of the engine, a display including an input connected to the controller, and a wireless receiver connected to the controller. The wireless receiver is arranged to receive a signal from a wireless device to cause the controller to send an engine start signal to cause starting of the engine and wherein the input when actuated causes the controller to send an engine start signal to cause starting of the engine. In at least some implementations, no keyed ignition switch is provided to start the engine and the engine is started only via the wireless device or the input.

Abstract: In at least some implementations, a throttle body assembly for a combustion engine includes a throttle body having a pressure chamber in which a supply of fuel is received and a throttle bore with an inlet through which air is received, a throttle valve carried by the throttle body with a valve head movable relative to the throttle bore to control fluid flow through the throttle bore, and a metering valve carried by the throttle body. The metering valve may have a valve element that is movable between an open position wherein fuel may flow from the pressure chamber into the throttle bore and a closed position where fuel is prevented or substantially prevented from flowing into the throttle bore through the metering valve.
