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

Just joined this group. I have a mason engine model c.  Which is in a locomobile steam car. It looks the same as your engine except it uses all ball bearings even the cross head slides. My question is did you replace the rings. Ive been driving the car for sometime now and need new rings, getting blow-by on both cylinders, the engine will no longer run. Looking for a source for them, or else i will have to machine them.
