I remember the days when people told me this concept was useless and I said "I'll show you!!"

Those were very screwed up days, as they were right! I haven't built an engine of this type in a long time. Why? Useless. That's why. It's an interesting concept but normal engines are ultimately better. Complicated to build, horrendous vibration, only run well with a very heavy flywheel and still run terrible compared to piston engines....

I'm probably not going to build any more of these. Concept officially abandoned!

Edit - it works now.
