Can anyone tell me the piston/cylinder specs for a NS8B 8hp Nissan Outboard engine?

Question

I am trying to do a major rebuilding of my 8hp Nissan outbuard engine and I need the specifications for the cylinders and pistons so I can check the tolerances and order the rings. I don't have a service manual. Any help would be greatly appreciated.

Hay, a general rule of thumb is 2 thousandths of an inch to every 1 inch of bore;) good luck
