ABSTRACT:
The invention is directed to a starter arrangement for an internal combustion engine wherein a manual starter device is combined with an electrical starter. Handheld portable tools such as motor-driven chain saws, brushcutters and the like are driven by two-stroke engines which can be started with a suitable manual starter device such as a pull-rope starter. Pull-rope starters require a forceful yank on the pull rope which is difficult for persons having inadequate physical strength. For this reason, electrical starters are provided to facilitate starting such handheld portable tools. The invention combines an electric starter and a manual starter device wherein the overrun clutch of the manual starter device includes a latching device and a drive member and is combined with a further latching device which coacts with a drive member driven by the electric starter. The engagement with the overrun clutch of the manual starter device makes possible a compact configuration so that the overall volume of the unmodified engine is not significantly increased notwithstanding the arrangement of the electric starter.
