compression

[rossi]

I ran a compression check today on a buddies 1990 Merc 150 carb with relieved exhaust being the only mod. The compression was 114 - 116 on all cylinders. Does anybody know if those numbers look good and if not what would a proper compression reading be.

thanks for any help

Remember that gauges can vary a bit from one gauge to another. The important thing is even numbers, 114 to 116 is pretty doggone close. :cool:

Thanks Rick, your words are appreciated.
