The distributor will in no way whatsoever affect cylinder pressure. No way no how. You can throw it in the ditch and cylinder pressure will be the same.
I was reacting to the statement that the motor was hard to start, no power,,,I saw the low compression comment, but without seeing a number it’s hard to tell how low is what low is.
It could be a bit low because the rings have not seated yet.
I was suggesting check the easy stuff first.
