So I bought a used Stihl 028 AV Super off of craigslist. Cosmetically there isn't a scratch on it. Heck the plastic to cover the logos are still there. when I fired it up it ran awesome so picked it up for $175. got it out the first weekend it fired right up started going through wood like it was it's job! loved it! then about 15 min in it started dying at the high end. felt like it was a little lean so I read the manual and it sounded like i needed to turn up the high rpm setpoint screw thing. So I did and it ran like a champ for the next 4 hours! we even fell most of a 40" tree. I stopped my Stihl for the last half hour while we were using a wedge to fall the tree. once it was on the ground well tried to start it up again and it wouldn't even attempt to start.
so I took it to a dealer and after three weeks they said that I had scored the cylinder wall from running too lean. :-( so they considered it junk.
So I ask the real pro's should I attempt to resurrect it or buy a brand new saw?

anyways any info on the saw like what parts to look for cylinder size etc would be most helpful
