No I did by running cheap pump gas and already knowing better.
Switching to boat gas and storing it in a steel VP fuel barrel at my place. No more mistakes with the brusiers coming back to life. Feels like the season of the witch.

For the purist.
Still makes the hair on my neck stand up. Five minutes you don't need back.
Good stuffs!

Especially if it is still hot!

Have a 441 here looks exactly like your piston always ran on Stihl silver bottle mix oil. Ultradirty, yup.
And does it really matter if its doing that ?
I can't see where that funny ripple of brown affects anything. These ring lands were not clogged up like most times when I see this accumulated brown. It does remind me of castor oil.
That said castor clogs things by design. Stihl oil usually plugs up the spark screen and then the exhaust side ring lands from heat because it just can't breathe.
I have seen the screens clog with Amsoil and Husky oil prob a ratio thing.
They did run 50-1 in all eight of those saws from that guy. Always purchased new he said. The headge trimmer and 200T wouldn't even start with the spark plugs and screens in those. It was ugly in every single muffler. His dealer tuned them fat, too fat. I buy everything when I see that. Left with ten tools from there.
He has a damn near mint 084 I'm going to buy someday they still cut big stumps with. Runs a 404 41 looks like new still so the guys hate it he said. Maybe has twenty tanks through it or less he said. Small crews don't like big trees with miniskids and only a twelve inch chipper.
I'm not that knowledgeable about chainsaws but want to learn about them so i try things... And that piston almost gave me a heart attackHave no idea why you removed the muffler to begin with but I would put my money on the ethanol. Worse thing they ever did and it is hell on a 2 stroke. Especially hard on the carbs. They also lie about the content in fuel. Lord only knows how much there really is in there. JMHO
yeah I agree on the bad petrol, but I by for my mix expensive one only.Coking caused by ashless oil.
Strato engines like this are more susceptible to this because the pistons run at hotter temps.
If allowed to continue like this the ring lands will plug up and that will result in more wear and or a loss of compression.
Fuel doesn't cause what's pictured.I'm not that knowledgeable about chainsaws but want to learn about them so i try things... And that piston almost gave me a heart attack
What oil do you suggest?
What's available in your country?
An actually certified JASO FD oil will be decent.
If you want to stick with a OEM oil. Husky, Redmax, Echo, Shindaiwa all sell good oils.
Not familiar with Hp super, but Motul 710 is very good and clean burning
Any of those will work well besides for Ultra.
Carbs running rich cause screen plugging, not oil ratio.
I have yet to see an oil failure even with browning.
Me either. My oil failures always seem to be when it is absent.
