Purchased this four stroke a couple of years ago. Trying to get it running, but it has no ignition system. I am experimenting with a set of MG points attached to the rear gear cover using the gear cover studs. Just going by old pictures found online. The threads are not metric as far as I can tell Something like 5/32" diameter X 36 threads per inch. Thats measuring OD of the thread. I have attached some pictures.

If anyone has drawings or information on this engine or the thread sized used in its construction, that would be most helpful. I think it may
have been a kit or home cast from magazine plans or something?
