Hi, I've included it in one of my other videos, it's now going slower than this; basically I've replaced the pushrod return spring and exhaust valve spring with ones from pens cut down to suit. The governor spring has been replaced by one with one I made from 0.2mm piano wire. I've also glued an extra wedge of copper onto the governor latch to reduce the interaction from the cam.
Fantastic! Great job.
That is the best running engine I've seen yet. You could list all the modifications you did, to help the rest of us out. Very nice!
