Re: compression on a rude'
Generally in the 100 psi.+ range, but as long as they are pretty equal you should be alright. You don't want one at 60 psi. and one at 100. psi.. If they are both at let's say 90 psi. your O.K.. Decarb first then take a compression reading, sometimes you will get a little higher psi. once the carbon is removed from the rings.
