Abstract
The present disclosure relates to a starter pulley arrangement for an internal combustion engine. The arrangement comprises a cord drum (1) configured to house a starting rope wound thereon, a driver (3) configured to interact with a flywheel (5) or other part connected to an engine crankshaft, and a torsion spring (7) connecting the cord drum (1) to the driver (3), such that the cord drum can resiliently urge the engine crankshaft via the driver. The torsion spring (7) is tensioned in a resting position where the driver does not influence the crankshaft. This provides an improved resistance against wear on the parts of the starter pulley arrangement.
