How to start a lawn mower with magnetron?

Starting a lawn mower with a Magnetron ignition consists of spinning the flywheel, either electronically or manually, by means of a pull-rope. The voltage induced with each spin goes to the primary coil, which has about 75 turns. It induces a larger voltage in the secondary coil, which has more than 4,000 turns, and produces a current of about 10,000 amps, which is sufficient to jump the gap between the spark plug electrodes. The spark ignites the fuel, and the movement of the piston pushes the flywheel through another revolution, creating a self-sustaining cycle that powers the lawn mower.
