I recently purchased a used 026. It is in good cosmetic condition w/ new bar & chain but not running. A squirt of carb cleaner in the carb and it fired briefly on the second pull. Before going further, I decided to pull the muffler and check the piston. Looking through the exhaust port, there are light scuff marks on the piston on about half of the upper part of the piston. They don't look like "scores" but more like scuffs, but is there a difference ? Is a score defined as a scratch you can feel with your fingernail or a pick ?
Several years ago I re-ringed a Homelite SXL (with worse scuffing) that still runs fine but I don't know if a Stihl will tolerate this type of repair. I believe saw is worth salvaging, but $284 for an OEM cyl/piston set is pretty steep. Would you pull the cylinder and piston to see if the damage may be more extensive than the piece of the piston you can see through the exhaust port. Any help is sincerely appreciated.
