An engine starter comprises a flywheel relatively rotatably mounted on the engine crank shaft and an electromagnetically operated clutch for selectively connecting and disconnecting the flywheel and the crank shaft. The rotational energy of the engine started by any conventional starter is stored in the flywheel which keeps rotating when the flywheel is disconnected from the crank shaft, and the stored energy in the rotating flywheel can be used to crank the engine.
