I can't see anything to worry about. Check the compression, then check it with a couple of squirts of engine oil down the bores, using a a little oil can. Seem consistent though.

As above, hot compression readings look sensible. Are you running about 10:1 CR?
Cold readings are however lower than I would have expected.
