Pic was from AS. Tree service saws. I figured with all the damage to the crown that it was bad gas or water in the gas

Might better just get a 562

Maybe after the first 2 or 3 took a chit you would start to wonder. Maybe even before you smoked the 4th. Lol

Yeah. Not sure if it happened all at once or not

“It started to run really good for the last 2 minutes then it didn’t want to start... can you fix it I need it for a removal tommorow and can you file the blade for me and straighten the arm I think it’s bent”

All this Shell Rotella talk gots me thinking why more don't trust such a big well resourced company with such a long track record to source their 2T oils from. I do, but the cheap lawn oil on the left is not the way to go it runs well but will fill an exhaust port full of carbon fast....bright stock but the other two oils are 2-3x the price and built with nice ingredients, SX straight mineral & VSX semi synth. Missing is the full synthetic black bottle but we don't need that.

Shell has never marketed their two stroke oils in the USA that I remember.
When I ran a fiahing lodge in Canada I did run their outboard oil for awhile and it wasnt great. Esso/Imperial/Mobil was much better.

None of them were mtronic. After a complete rebuild, one of them only had one tank of motomix run through it and one of those pistons above came from that saw. Tuned to 13,2k

So wait, they burned down a couple of saws with what we believe is bad fuel, rebuilt them, and then proceeded to do it again?

Presumably with the same bad fuel?

???

That's what the thread States on a s. The saw was rebuilt, vacuum checked, and send out with a can of motomix and it failed on the first tank

To my untrained eye the damage to all 4 is similar enough that I would think whatever wrecked them was the same in each case

I guess its possible a batch of Motomix with wayyyyyyy too little oil or possibly no oil got out but you would think the interwebs would be flooded with burned up saw pics and stories

It looks like someone threw a tiny little thermite grenade down the plug hole cause again, to my untrained eye, they look MELTED

I agree 100%. Stihl wrote it off as operator abuse

WTF!!!!

 

[huskihl]

WTF!!!!

In the other thread he said that the saw got hot enough to melt a plastic parition on the intake side of the motor. The guy kept running it and it did this. Seems like the chains would have to be dull and they just kept dogging the saw in to get them to cut. You'd think it would take hours of operation to do that.
