Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

My low cost D105 ebay find showed up today, much to my pleasure it is unfired and survived shipping with zero damage.
  I had to try it on my new air pump and it came to life with authority, as I have mostly run occilator type engines on the pump lately the advantage of a slide valve engine is obvious. It does run about 30% faster with the govenor disconnected, I have often thought Wilesco runs the spring belt tension a little high. I stretched the spring belt just a little and this helped bring the speed up with govenor belted, however the joint of the spring belt now looks lumpy as it travels, this doubled area of a spring belt joint is a "hard" spot so it does not travel as smoothly. I may make up a black o-ring belt to see If I can get a smoother operation out of this feature.
  I am having second thoughts about cutting this engine up for parts, original plan was to harvest the cylinder/valve/rod group for a power upgrade on my Mamod Roadster build and use the boiler/base to power one of my kit steam engines...
