Abstract
A small engine suitable for hand-held work machines such as cleavers and chain-saws in which the engine is started by driving a self-starting motor with the electromotive force of a secondary battery and wherein the size and weight of the engine is reduced by eliminating the use of a generator since the secondary battery is charged by utilizing the electromotive force of a magnet in reverse direction that is not normally used for igniting the engine.
