What is the acceptable piston/cylinder compression range as measured at each spark plug hole?
And if there is a certain procedure to follow to due a test please advise.
I got 110 PSI, by threading the hose of the compression gauge into each spark plug hole and turning the engine over for about 5 secands.
Thanks in advance for any help.
 
The motor appears to be working fine. I was just doing other work on it before handing it off to one of my kids.
I am just looking for verification that the compression is good as there is a chance I may be selling if they change their mind.
Thanks for your reply.
