  • Patent number: 6244233
    Abstract: A pull-down engine starter has a pull-down line (1) that is attachable to a takeoff line (15) or directly to a rewind-starter wheel (14) and pulley-routed to a suspension pulley wheel (6, 25) from which a handle end of the pull-down line is suspended to conveniently grasping proximity to a user position such as a driver seat (8). For go-carts (4) and other rider-operated vehicles (12) with engines (3) having rewind starters (2), the user position is a driver's seat or a machine-operator position on the vehicles. For walk-behind machines (23) and other non-ride machines such as a generator set (24) with rewind-starter engines, the user position is generally lateral to the engine. Singular-suspension pulley wheels (25) are provided for singular-wheel pull-start lines (22) on head-high pull-down anchors (26) and waist-high pull-down anchors (27).
