Hi Mike.

Not sure if you're looking for info re low reading on #2 but....

Did you try putting a little oil in the low reading cylinder? If it
brings up the compression, it could be the rings/piston. Squirt some
in, (teaspoon amount?) spin a few times then take a new reading.

I'm sure I'll be corrected if that's bad info, but may be worth a try.

Are the valves all adjusted correctly?

Neil.
