Not sure where you are located. I am near Detroit, MI.
If you feel your Supass is a bit low on power I would be willing to help out a bit. I have a ring and bearigs on hand. Should put some bounce back in the old OS. If you care to send the engine I can go thru it and return it in a couple of weeks.
I do have references if there is any concern.
Glad to help, enjoy the new plane.
