Engine Compression Test
compression range is 140-270psig, variation is 28psig max. Good numbers, however, would be close to 200psig or above and within 5psi of each, 10psi max. if there is >10psi difference, you've got a problem. variation is more important than overall maximum pressures.

crank it over 3 times, the third time is what you record; it should be about twice as high as the first stroke.

mine were all at 149-151, with 125k, so yours is fine. stop worrying about it, theres nothing wrong with your engine as far as a compression test goes.
