We had two in the family many years ago Steve. Don't know how much I remember about them, but I'll try. I remember that they had buzz coils and a magneto flywheel. Both of my dads had electric starters and a battery. It was really funny when he shut the engine off and he wanted to start it again, maybe about one in ten times, if the engine was still hot, you could turn the ignition on, a coil would buzz and it would start all by it's self.
