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

Bonjour Jim,
I am happy to see your engine finally running and I am just surprized by its speed.
This one is quite slower :
I also had a lot of difficulties to start it (see my other videos), mainly because of the plug and the setting of the mix gas/air which seems furthermore to be modified by the ambiant temperature increasing with the run.

This one also had 3 major issues :
  - Broken spark plug giving erratic spark
  - Poor ignition timing
  - Leaks at the valve seats
