ABSTRACT:
An engine starter with a rotatable drum, a spring, and a planetary gear. An axially extending clutch bushing is permanently connected to one end of the motor shaft. The clutch bushing is via a clutch connectable to the sun gear, the clutch not engaging until the bushing exceeds a predetermined number of revolutions. Thus the spring of the engine starter is not retensioned for a new start until the engine has come well into operation. When the torque of the engine starter has reached a predetermined level the clutch disengages so that the spring is not broken.
