Abstract:
An engine starting system, comprising:a power source having a first terminal electrically connected to an electrical ground, and having a second terminal; a single electromagnetic coil having a first terminal electrically connected to the electrical ground, and having a second terminal electrically connected to the second terminal of the power source to receive an electrical signal from the power source; a core having a magnetic field induced from the electromagnetic coil; a choke valve, disposed in an air intake of an air/fuel-mixing device, that moves to a closed position in response to the magnetic field produced by the single electromagnetic coil; a biasing device that biases the choke valve to move to a substantially open position when the magnetic field is interrupted; and a free wheeling diode electrically connected to the first terminal and the second terminal of the single electromagnetic coil.
