RE: 25cc 2-stroke conversion
OK it looks like captainjohn called it right..this is the same engine in the "What a deal thread". It looks like much has already been done on this design.
Anyway this thing looks like it does have some really great potential. It's light but will likely need some porting changes.
The carb definitely needs to be replaced. Hopefully Ken Lambert is still making mufflers for it. So far I haven't found a prop adapter appropriate for gas / glow (ie no flywheel).
Anyway I would recommend that anyone interested in this conversion now go to the "What a deal" thread to learn more about the potential of this engine.
