Well, I pulled the exhaust cover this morning. Screws came out like it was a brand new motor. Not one gave a fight. I found the lower piston has a large gouge in it starting at the top ring and going through the other two rings and down the skirt. This has the rings locked up and the lower half of the cylinder has a corresponding gouge from the top of the port down. I guess this power head is done. My shop camera does not take good close ups, but if you look at the 3rd port from the right you can see the damage. I have another power head from a 62 that’s good so I guess i’ll swap it and make it a good motor again. It’s really a shame as this is about the cleanest original FD I have ever come across.
