Got a new piston for my SD120 - as you can see the old one (sitting on top of rewind starter) wasn't that bad. No scratches, but the finish
had worn. I could only get 125psi for compression. The second shows the cylinder which is pristine, maybe TOO pristine. Should I scuff it up
and what would you guys recommend, 600 black sand paper? Tried to buff it with the red scotch brite and that seemed to make smoother. I have
a small ball hone that would fit but I don't want to ruin it. Would a hand sand with ??? grit sand paper be OK?
