More teardown photos









There are deep pits, probably caused by corrosion and then the engine being turned over. The ring will swipe against these, I cannot imagine that is good for the ring. This cylinder will make a nice pencil holder.




The proximate cause of this teardown was a 19% leakdown in this jug. I am going to de-carbon the head then disassemble and measure the valve stem diameter, valve to guide play, overall valve length and the valve margin remaining on the face. If any of those items are out of spec, or there is any damage to valve margin or the seat, the head will be rebuilt. If not, the valve will be lapped and put back into service.
