Hi Paul,
Can you put up a pic of your mower, Turner used 3 different Kirby 4 Stroke engines on their mowers. Impulse starter you will have to keep an eye out on EBay for. If your engine is the later Kirby you can still buy new points for it, check with them if it suits your model. No points listed in the ODK shop but some here.
