Take care Tony.

I like the idea of adding o-ring to piston, would you say it improved the power or run time?

It will improve both power and run time going on what has happened to previous engines having 'O' rings fitted.  The Roadster isn't mine I am just putting it back together for its owner so, I haven't run it other than with the ring fitted. The Roadster doesn't have a regulator it uses the steam as it is produced this with the fact that it uses tablets as fuel which are a bit variably as a heat source it might be difficult to tell.  So, because of this unless there is a dramatic improvement it might not be noticeable, maybe the owner will be able to say. 

Take care Tony.
