Not bad for a Stirling engine
One of the problems was the main bearings as designed they moved about like rotten teeth. Instead of two separate parts I made it from one piece
I may have made the problem worse as I did away withl most of the dead space in Rudys design and it did boost the engines power
It now has the fire box and other bits n bobs that were missing in the video but just never got round to painting it a job I dislike thats why my engines tend to have worked finish
Thought I had a couple of others then remembered they are P Duclos engines
cheers
