So, when I mentioned a 'leak down' test, I meant that I poured about a tablespoon of oil down the spark plug hole, and then did the test again. Is that what you meant by a wet test? On cylinder #3, than led to an increase from 95psi to 150psi. So, you are claiming that 120 on #4 vs the 95 on #3 is not too critical? How low of a reading would I be seeing if I had bad piston rings or valves? I did not remove the cams or shim buckets. I had not read about that. How would I do that and what is it for?

Also worth noting, I forgot to keep the throttle wide open for the test. I did remember to open the choke all the way. Would you recommend I redo the test with an open throttle, in order to get a more correct reading?
