Patent ID: 7066162

Claim:
A method of starting a two-stroke battery-less engine, comprising: (A) driving a rotational component of the engine to rotate by manually actuating a rope-start mechanism to provide power to a control system and thereafter; (B) detecting rotation of the component through first and second rotational positions thereof; (C) determining, based on the detecting step, an absolute rotational position of the component, the determining step occurring before the component rotates more than 270°; then (D) enabling an engine firing sequence immediately upon determining the absolute rotational position of the engine, the enabling step comprising enabling the supply of energizing current to at least one of am electronic injection system of the engine and an electronic ignition system of the engine; then (E) detecting rotation of the component through a third position which is angularly spaced unequally from the first position and from the second position; then (F) determining, based on the step (E), whether the component is rotating in a forward direction or a reverse direction; and (G) disabling the engine firing sequence if it is determined in stop (F) that the engine is running in the reverse direction.
