I have a Stihl 031av that has been losing power. I pulled the saw apart and the pistion has very light score marks on the intake side of the bottom skirt of the piston. Your fignernails barely catches in the marks. Can that piston be reused with new rings. The jug looks like it is in excellent shape. Also does anyone out there have a repair manual and parts. I know the supply direct from Stihl is limited. My local dealer is of no help as the only thing he wants to do is sell me a new saw ( He is recommending a MS290 looks like a cheap plastic saw to me). I appreciate anyone who submits sound constructive responces. Thanks Glenn in Maryland
