I have not tracked down the culprit, but it sure was a bad year for all my saws. We mix our 2 cycle gas 50 gallons at a time, and I may have had some 2 cycle gas mixed with 80-90w axle grease for some of the problems. Since it went on all year, and I didn't get around to fixing them until recently, it couldn't have been just one batch of bad gas. Besides, not all the saw or string trimmers got damaged
All this happened last year!

3120xp; 13 years on it's original piston & cylinder, a brand new cylinder & piston failed after 2 hrs run time. No, it wasn't burning lean, and it looked like it was good gas. I think we had a ring failure. New again, I haven't had any tree work to test it on.
372xp: Gone, mysteriously. Left out and stolen on a job, most likely, but the employee that is suspected never reported it.
365xp: roasted cylinder, we tried to save it with lye scrubbing out the melted aluminum. Big bore kit still on order.
359xp: new piston, we saved the cylinder.
268xp: Not even my saw, it was abandoned here by one of my climbers who returned to Michigan. I think he left it with us to pay me back for the ms-200t that disappeared on his watch, as well as some other climbing equipment. New clutch, some screws, and servicing: it's running great. He foolishly left it at our shop with my mechanic (now gone) under the presumption that he knew how to fix it. The latest mechanic got it running real good on about $50 worth of parts.

066 #1: Well used when I bought it, it roased the cylinder & piston. New parts now, it seems to run fine.
066 #2: purchased almost brand new, it didn't last long. Still in pieces, it needs a cylinder kit. I have been waiting to see how our other rebuilds last before wasting more money on parts.
029: new piston & cylinder. Another meltdown back in service.
200-T #1: mysteriously absent after a good day in the tree.
200-T #2: junk, many parts taken to replace fuel tanks and other parts for keeping the others going. Initially dead on low compression.
020-t: Similar to #2 above, this poor saw got broken, salvaged, melted down, and finished off. Not worth fixing for all the missing parts.

757: long a problem with the muffler bolts, the piston finally died. New cylinder and piston, everything seems great now.
577: a new piston seems to have put it back with fine compression, running great now.
I have been through several mechanics, and I hope I have eliminated any tendency to adjust the saws to burn lean. The current mechanic is well versed in pressure & vacuum checking the crankcase, so I hope we won't have wasted our efforts.
I have always insisted on mixing the gas myself, but I am going to go back to buying "no alcohol" fuel from a distant location. It's pretty hard to find in our area, and I got a bit cheap and lazy. That won't happen again!
Throughout all the saw problems, my little Echo CS-4400 ran great. It got so bad, the tree crew wouldn't take anything but that little saw to go to work with. Right now I am flush with big, bad chainsaws, ready to work.
Nothing to do, the phone has been dead, and people don't seem to even be price shopping. If it wasn't for all the snow removal, I would be out of business. Never underestimate the amount of damage that a poor employee can inflict on your business & equipment.
