I honestly feel sorry for this guy. He comes in here asking for help and instead gets led on a goose chase causing him to believe his saw is junk. Misinformation is worse than no information.
me, too. more misinformation! ~

There, I fixed your first sentence for ya. There really is too much over thinking going on IMO.
I use to have a 4 wheeler that had stripped spark plug threads. Before it got fixed we would ride the snot out of it with the spark plug finger tight.

Don't take this personal but I feel the need to interject some sense here. There isn't a damn thing wrong with that piston or that cylinder, I still see the machine marks in the piston in the pictures and there is no transfer on the cylinder walls. Second of all, its never a good idea to scuff the piston rings with an abrasive... period.
@inbilya, put the sandpaper down and step away from the bad advice. Pick up a can of Brake Kleen, spray the piston and rings off, let dry (compressed air helps), add a drop or two of fresh 2-stroke oil and lightly coat the piston skirt and assemble. Clean the cylinder walls with a lint free rag and a couple shots of cleaner. Lightly oil and reassemble. If you would like to clean up the piston top some you can take a brass wire brush and some of the Brake Kleen to it but its probably not worth the effort.
Get the saw back together and check that the issue is still present before you do anything more. You don't want to introduce any more variables.

Either a fuel or ignition issue has caused some erosion on the piston crown, but there is nothing here to warrant sanding anything.
It does not take more than a couple drops of oil to assemble a topend. How much oil do you think is on it when you shut it down?

Right there.I would not hesitate to run some 600 grit w/dry paper longitudinally using gasoline only as a cutting agent. lightly, just to scrub things up. not to hone! this assumes for next run, same rings. if it was mine and I did scrub cyl once precleaned or carbon and any grits in there, they will all have them... once taken apart... I would not have a problem lightly running the 600 across the face of the rings. I said lightly... and not to remove metal, merely to lightly upset them a skosh. remember, this is my approach, not joes toms or bills, lol who are they? I am an engine builder. with a lot of experience. but I am not a chainsaw engine builder, but I am a tuner, too. i have a lot of dif 2-stroke engine/tuning exp. and I am a very expd porting and carb modifier, too.
This saw has nothing more than a fuel and/or ignition issue.maybe the modder should just delete all the posts here, but yours... the one in reference to 'try a new plug!'
lol
If you can't defend your position with personal insults, then perhaps you should reconsider involving yourself in this discussion.

Right there.
In 100 words or less, why don't you tell the OP what you would do to return this saw to normal operation conditions.
Your arrogance is nauseating, and not the least bit convincing. The fact that you can't even differentiate between a reasonable defence of your position and a personal attack is very telling.
Seriously? Do you really think people buy your crap? The only defense you have of your opinion is to make fun of and suggest that I don't have a clue, all the while attempting to present a clearly fabricated air of superiority. That's a weak man.thank you Mr Snelling... I can see u r not used to debating sound engine building/repairing techniques well with other industry professionals... oh well... each is entitled to their own opinions....
