ABSTRACT:
Disclosed is a starting device for an internal combustion engine having a stationary bearing axle attached to the engine, a pulley rotatably mounted on the axle and adapted for accepting a starting rope wrapped thereabout, a recessed coupling attached to the drive shaft of the engine, coaxially surrounding the rope pulley in its recess and having a plurality of inwardly facing ratchet teeth. The starting device comprises an elongated pawl pivotably mounted on one side surface of the pulley, the pivot point being spaced radially from the rotational axis of the pulley; a follower pin protruding from the pawl in the direction away from the pulley side surface at a point spaced from the pivot point; and a spring member elastically engaging the distal end of the bearing axle and comprising an elongated guide slot for receiving the follower pin, whereby the spring member retains the pulley on the bearing axle and swivels the pawl radially outwardly into engagement with the ratchet teeth in response to rotation of the pulley.
