Welcome and back to your original questions. Your compression is OK, not great but OK. Also, if the engine hasn't been ran regularly, you will likely see that compression increase a bit with regular use. there are techniques of putting Marvel Mystery Oil in the cylinders after use to let is help clean any deposits on the rings, etc.

How do the spark plugs look? That's a great indication on how the engine is running.

Regarding cooling, are you fresh water or raw water cooled?
