This is a Genuine OEM kickstart and hand lever starter return spring for JAP single-cylinder engines, supplied under OEM No. 21769. It is a flat spiral spring made from durable spring steel, designed to store and release energy so the kickstart and hand lever return smoothly to their rest positions after each use. Suitable for vintage J.A.P. industrial engines, it is a direct-fit service part for models such as the JAP 4/3 and JAP 5, helping maintain reliable starting and control of the mechanism. As unused old stock, the spring may show minor tarnishing or storage marks, but this does not affect performance.
