What is the Highest compression I will get when I rebuild my single 787?
What is the lowest compression I should get when I need to rebuild my single 787?

Generally speaking, 150 is perfect and 120 is low and will need service shortly..

So the guy that was getting 160 after a rebuild was not testing it right?....
