A good one will have 100 psi, so you have a long way to go. Did you check ring end gap before reassembling? Not sure what the spec is but it’s probably in the .010 to .015 range. They absolutely get worn out and also are prone to rust pits in the cylinders, from being carried around and stored upside down or what ever. (They are often found seized up.) They also like a good head gasket, although hopefully that’s obvious. Sometimes you can get them to fire briefly by putting gear oil in the cylinder and immediately trying to start it. It my fire or run for a few seconds and quit; but it helps verify you have a compression problem.
Long live American manufacturing!
