I have a question, do you know the bore of the 5 hp vs. the 6.6 hp? I have a '58 in the shop according to the serial number but it still has a cast iron carb on her. Reason I am asking is I have to order rings for it and want to make sure I get the right ones. The piston and jug are perfect but the top ring was broken apart.

Strangely enough, Bore and stroke are the same from 5hp to 7.6hp. 2.25 bore, (off the top of my head)

Further info...

Bore 3.24
Stroke 3.50

Rpm 2600-2800

I was a bit surprised at the displacement, I had no idea it was that much.
