carboned up?how do i prevent that?At least 2 of those plugs look carboned up pretty good. Not normal.

With less oil in the combustion chamber. Either bad mix ratio or rich high needle is your problem. Both would foul a plug like that.carboned up?how do i prevent that?
I agree this "smells" operator error a long way, too much oil and/or a too rich carb setting....
MTronic yes, if they can get the mix ratio somewhat close to 40-50:189 octane fuel and orange bottle oil is not likely to be causing your problems. I do recommend the Ultra, but saws will live MUCH longer than 6 months on the orange bottle stuff. 89 octane is what Stihl recommends. I do think MTronic saws would be a FANTASTIC idea for you.
I don't think M-Tronic is going to solve anything if someone doesn't take mixing fuel seriously.

change the plug more often, its a 2 stroke they get carboned up even under ideal conditions when you put a lot of time on them....
Or... the amount of oil required for 5 Gals is being mixed in whatever size jerry can is available. I mean I could tell you right now if I told one of my junior staff to mix 2 OZ in a full jerry can, they wouldn't hesitate to mix 2 oz in any sized jerry can. 5 gal or 2.5 gal. Because I only specified the 2 Oz. Point being if they don't understand the point of mixing oil then its all the same to them anyway.Post #19 almost leads me to believe fuel is being mixed in the saw and this would explain everything.

i thought it has been said on here to use between 32-40:1 do we really think they have been using more than that. the muffler screens look dry and rather clean.
wondering how many hours they are putting on their saws. 30 hrs a week?? times 24 weeks = 720 hrs how many hours would one expect to get out of a saw.
i think they should sell them every six months, and get new ones. or inspect and or rebuild the top end if needed. and the saws would last even less time if the oil mix was lean or the carb was set lean,,,, if i owned the company i would set em rich and mix the oil rich too!!!!
XSKIER do you care to comment here?

well a saw is not always in a cut while running, and not sure if this guy is logging, tree service, or firewood guy. and for business use the saw has a purpose,,to get the job done, they get scratched,dented, run over, slid around in the back of a truck, dropped, and neglected, just like the people using them....A saw will often resemble the person using it... Do you wear a suit and tie to work?OK Ken,
I would be curious to know how many hours are actually on this particular MS 362. Figure an average limb of about 8", about 10 sec per cut, 720 assumed hours, that saw should have made about 259,200 cuts. I'll never know how fellers figger they can receive "thousands of hours" from a chainsaw, maybe if thousands of those hours are spent skidding, splitting, rigging, carrying, and travel time. But alas, the 562 is not off the flimsy list because of this story...
