i bought another xp the price was right, it has compression of 143 and 150 i am assuming thats pretty good. the machine looks spotless. would you say i am good with compression.

seems a tab bit low. usually =/- 5 psi you are good. what cylinder is it? you may also just have a weak battery. how does it run?

airborne, you are talking about the difference between the two cylinders right? because i thought anywhere 135 and up on the 951 is good

yes.I am taking about the differences between cylinders. the 787 has higher compression. on a fresh rebuild you should be seeing +/-5 psi from 155psi
