Abstract: A control system for a small engine operated device includes an emitter carried by the engine or a portion of the device spaced from the engine and a control circuit. The control circuit may include memory with which control data related to device conditions, engine conditions or both is stored, and a processor in electrical communication with the first emitter. The control circuit provides a signal corresponding to the control data to the emitter so that the emitter provides an output in response to device conditions, engine conditions, or both.

Abstract: A fuel system that in at least some implementations includes a carburetor having a fluid passage, a solenoid, a valve, a driver circuit and a control circuit. The valve may be moved by the solenoid between an open position permitting fluid flow through the fluid passage and a closed position at least partially inhibiting fluid flow through the fluid passage. The driver circuit and control circuit are communicated with the solenoid to contribute to providing power to the solenoid and controlling actuation of the solenoid. The driver circuit and control circuit provide a first magnitude of power to the solenoid to initially change the solenoid from its closed position to its open position and a second magnitude of power to maintain the solenoid in its open position wherein the second magnitude of power is less than the first magnitude.

Abstract: In at least one implementation a carburetor includes an intake bore with a port opening into the intake bore, a fuel chamber from which fuel is supplied to the intake bore, and an accelerator device including a fuel reservoir. A fuel flow control valve is provided between the fuel chamber and the port to control the flow rate of fuel to the port and at least one passage communicates the fuel reservoir with the port and fuel in the fuel reservoir is supplied to the port therethrough. The passage also communicates the fuel reservoir with the fuel chamber. The fuel flow control valve is located between the fuel reservoir and the port and between the fuel chamber and the port, and the passage includes a portion extending between the fuel reservoir and the fuel chamber independently of the fuel flow control valve.

Abstract: In at least some implementations, an engine control process includes an engine speed test and other steps. The engine speed test includes the steps of a) determining a first engine speed, b) changing the air/fuel ratio of a fuel mixture delivered to the engine, and c) determining a second engine speed after at least some of the air/fuel ratio changing event, Based at least in part on the difference between the first engine speed and the second engine speed it is determined if a change in the air/fuel ratio of the fuel mixture delivered to the engine is needed. If a change to the air/fuel ratio was indicated, the air/fuel ratio of a fuel mixture delivered to the engine is changed.
