Is there like a book or manual or something that's reasonably easy to get hold of that goes into detail about the engine as found in Heinke bubble cars?
It just occurred to me that I have absolutely no idea about how the Heinkel engine works, even basics. I guess I could take mine apart and have a look, but I would rather see it on paper first. Need to find a manual or something. Do they exist?
I know a similar engine was used in scooters, but it had different parts, no reverse, etc. Does any publication exist dealing specifically with the car engine?
