    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
