    Like a car engine, there is a sparkplug.

    Two stroke, by means of compression and spark plug to move the piston up and down, thus causing rapid motion!

    An electrical current causes a spark between the two terminals of the spark plug. Hence ignition. The explosion of the fuel forces a cylinder down which drives a shaft connected to the rotor blade.

    What else do you want to know?

    The spark plug is fired by current created when the magnet on the flywheel passes a stationary magnet.
