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

I am mostly pleased with mine, and it generally runs fine. There have been a few issues including having to chase the spark plug threads in the head with a tap, a fuel tank leak, and a bad CDI module, but all of those issues were easily repaired. It doesn't quite reach the level of detail and refinement found in Jin's engines. I would like to see further refinements in the exhaust valve blocking mechanism including scaling the parts down to better match the scale of the engine. Otherwise I'm good with it.
