Abstract: In at least some implementations, a fuel supply module includes a reservoir and a fuel pump carried by the reservoir. The reservoir may include a body and a lid that define an internal volume to contain a supply of fuel, and the reservoir may include an inlet through which fuel enters the internal volume and an outlet from which fuel is discharged from the fuel supply module. The fuel pump is carried by the reservoir and has a first inlet communicating with the internal volume to take fuel into the fuel pump from the internal volume and a second inlet spaced above the first inlet relative to the direction of the force of gravity to take fluid or vapors into the fuel pump from the internal volume. The fuel pump includes an outlet from which fluid is discharged for delivery to an engine through the reservoir outlet.

Abstract: At least some implementations of a method of distinguishing between two loads being driven by an engine, includes the steps of determining engine speed at defined intervals, comparing a second engine speed against a previously determined first engine speed, determining if the second engine speed fits an expected pattern of engine speeds, and counting either the number of incidents where the second engine speed does not fit the expected pattern, or the number of incidents where the second engine speed does fit the expected pattern, or some combination of these two. A method of determining if an engine is operating at least near a lean limit of its air to fuel ratio is also disclosed.

Abstract: In at least some implementations, a method of operating an ignition system for a combustion engine includes charging an energy storage device during at least a portion of the time when the engine is operating, permitting the level of energy stored on the charge storage device to decrease over time after the engine ceases to operate, determining the energy level on the energy storage device when the engine is restarted after having ceased operating, and setting at least one engine operational parameter as a function of the determined energy level. In at least some implementations, the at least one engine operational parameter may include one or more of: richness of a fuel and air mixture to be delivered to the engine, ignition timing, desired engine idle speed.

Abstract: In at least some implementations, a method of controlling a fuel-to-air ratio of a fuel and air mixture supplied to an engine, includes the steps of determining an engine deceleration event, determining the number of engine revolutions required for the engine speed to decrease from one speed threshold to another speed threshold, comparing the number of engine revolutions determined above against a revolution threshold, and making the fuel and air mixture richer if the number of engine revolutions determined above is greater than the revolution threshold. The method may also include determining if, before the engine stabilized at a stable engine speed (which may be an engine idle speed), the engine speed decreased below the stable engine speed as the engine decelerated to the stable engine speed from a speed above the stable engine speed, and making the fuel and air mixture leaner if the determination is affirmative.

Abstract: A power tool may include an engine, a tool driven for movement by the engine, a brake mechanism coupled to the tool, a charge forming device coupled to the engine and a transmission member operably coupled to the brake mechanism and a throttle valve of the charge forming device. The brake mechanism inhibits movement of the tool in an engaged position of the brake mechanism and permits movement of the tool in a disengaged position of the brake mechanism. The charge forming device is coupled to the engine to provide a combustible fuel and air mixture to the engine, and the throttle valve is movable between a first position and a second position. The transmission member is operably coupled to the brake mechanism and the throttle valve so that the throttle valve is moved away from the first position when the brake mechanism is moved to the engaged position.

Abstract: In at least some implementations, an ignition system for a combustion engine includes analog circuit components arranged to control ignition events at an engine speed below a first threshold of engine speed and a microprocessor to control ignition events at engine speeds higher than the first threshold. Hence, ignition can be controlled at lower engine cranking speeds to facilitate starting the engine at lower engine rotational speeds.
