I have made a start on the engine as I have finished painting the frame, I thought it would be seized solid and indeed it would not move. After removing the fuel tank I found the flywheel packed solid with dirt and leaves etc, after cleaning it all out I have movement. The engine will need a lot of work but if it is original it will be worth it, I have another complete running engine and a spare parts one just in case.
Here are the engine numbers
I believe the top one is from factory but why is it not stamped on the flat, perhaps because the air filter would obscure it?
I suggest the bottom one was stamped by SC for warranty purposes, it looks like the date of December 1957 2C or the 11th of May 1972? Not sure about the C or 2C though?
