This is the best compression/blowby test i have seen on the md7. Its actually great. Your approach and explanation is spot on, i get a really good understanding of the process and how to do it. Thank you!
no his explantion of blow by is wrong !
air out the intake or exhaust is Valve Leakeage. leakage past the rings will show up as pressure in the Crankcase !
on the leak down test (blow by) did you make sure you were at tdc compression stroke so both valves were tightly shut?
