Abstract
A rope-pull starting device for an internal combustion engine including a hub, rope pulley, rope and torsion damper spring. The hub configured to drivingly engage an engine when the hub is rotated in a first direction. The rope pulley interconnects with the hub by a torsion damper spring. The torsion damper spring coupled at a first end to the hub and at a second end to the rope pulley, wherein the torsion damper spring is coiled from the first end connected to the hub, toward the rope pulley, in a second direction opposite to the first direction, and whereby the rope pulley is rotated in the first direction when the rope is unwound therefrom and the torsion damper spring responsively urges the hub to rotate in the first direction.
