Re: Need Help on a motor

The better you can spin the flywheel the better your numbers should be. You might want to try spraying a bit of WD-40 into each cylinder to help loosen things up and then retest it. Also, make sure both spark plugs are removed when testing that will also help a bit. Pre the previous post, you're not so much looking for hi numbers as much as even numbers. There are many things to bring up the compression on a well balanced motor, but if there is a large discrepancy, then that's usually a sign of a bigger (worse) problem.
