Patent ID: 7520264

Claim:
An engine control circuit comprising: an electrical control device electrically coupled to a magneto such that said electronic control device controls the magneto to shut an engine down when the electronic control device is in a first state and controls the magneto to allow the engine to run when the electronic control device is in a second state; a portioning arrangement coupled to the electronic control device such that the portioning arrangement provides a portion of energy generated by said magneto to said electronic control device to place said electronic control device in said first state and shut down said engine; a diverting arrangement coupled to the portioning arrangement such that the diverting arrangement selectively diverts said portion of energy away from said electronic control device to place the electronic control device in said second state to allow the engine to run; a timing arrangement coupled to the diverting arrangement such that the diverting arrangement diverts said portion of energy away from said electronic control device to maintain the electronic control device in said second state and allow the engine to run for a predetermined period of time after an engine shutdown signal is provided and such that the portion of energy is provided to the electronic control device after said predetermined period of time to allow said electronic control device to change to said first state to shut the engine down.
