Whats up guys, I picked up this S25DA a few days ago, and must say it doesn't look like it was used much. One big problem though, the piston is scored, it has a decent scratch on the exhaust side. Compression seems really good, cylinder looks good from what I can see. Will need fuel lines, has a Walbro WA19 carb with 5/76 stamped on the carb. So I'll assume it's 1976 saw. I had the perfect B&C just waiting for this saw. Actually this thing is almost as nice as my NOS s25da. Also missing the throttle handle rubber, and carb cover gasket. So does anyone have any nice s25 pistons layin around or should I try to clean this one up.
