Here's an idea for you Bruce. Take the engine from a Jensen 70 or similar, make it horizontal
and low. Replace the spoked flywheel with a small thick marine style wheel. That'll keep the
height and length down. Should run with that mass spinning.
I like this more all the time Tommy , I have all the parts 🙃👍
Yes you do Bruce. You have the parts, the tools and know how. With your lathe and a hunk
of brass bar stock, you can make the flywheel to fit and look anyway you like.
With the way you like to improve upon things, I can see it now. Real bearings, everything
polished up, painted and shiny. Just do it!
