Default Not enough compression?

What is the minimum amount of compression needed for the 150cc? I bought a tester the other day and checked mine cause I still haven't figured out why it wont run and it is pretty low but it seems like it should still be enough to fire, maybe I'm wrong.

The reading I got was 105psi. It's the rings or cyl wall cause the oil trick bumped it up to over 150psi.

Would that low of a reading cause it to suddenly stop running? Because that's pretty much what happened. I never seen a gradual decline in power. It just quit.
