ABSTRACT:
A pull-starter for a combustion engine of an engine-powered apparatus having a startup element automatically actuated upon initial pulling of a pull-cord. The pull-cord is attached to and wound around a recoil pulley, routed at least partially around a portion of a movable dampener member, and attached to a handle. The dampener member is biased toward a rest position and a portion thereof is linked to the startup element. The pull-cord is pulled to displace the dampener member away from its rest position, automatically actuate the at least one startup element, and unwind the pull-cord from around the recoil pulley and thereby rotate the recoil pulley in an unwind direction to rotate a crankshaft of the engine via a coupling. At least upon release of the pull-cord, the dampener member and the startup element automatically return to their normal state during engine operation.
