Hello, I tore down my merc, found one stick ring on three different pistons. I bought new mercury pistons,wrist pins, rings and gaskets. The cylinder walls look great. I have 400 grit cylinder hone to deglaze them. Question is: the needle bearings look and feel smooth, will it hurt anything if i use the same needle bearings with the new pistons and rings? The reason i tore the motor down is three cylinders had 102 lbs compression while couple others had 124.<br /> Any tips i should do while going back with the rebuild?
