anybody know what compression my compression tester gauge should read on low comp accralite pistons on a frst, im getting 60psi on number 1 and around 100psi on the others,i know they should be the same so im ganna change the rings,but it would help if i knew how much they should be at! ive been told standard pistons should read around 150psi,would it be lower as they are low comp,or shouldnt that effect the reading??

thanks alot
