I read it then and reread it now. In my opinion what was reported then was inconclusive and not evidence supported. Maybe someone else?

You can think what you want, that's the nice part of living where we live, but other people, me included, may have our own opinion on this subject! And my opinion comes from real life happenings of my own in my door yard in REAL life. Yes, I will put a little shot of stabil in my gas can before I fill it up. Why? Because of this great ethanol crap we are getting served, it does help! Gas will start to break down, I've seen it in my chain saw - it would not start one time but was full of gas & I'd cranked the snot out of it; dumped that out & put fresh fuel in it and guess what, first two pulls' it fired and ran like a top! The gas I'd had in it came from a friend who didn't use Stabil, and had been sitting in my tank for a couple months. I too have worked in the tank farms and seen how this SWILL gets served to us and I've seen that everyone's gas comes from the same tanks, but some companies will pump their additives in at the loading dock as it's shot into the trucks for delivery! So, I will get off my soap box and keep on wasting my money for the peace of mind that I get knowing I will not have troubles down the road!!! Have a good day! Oh, P.S this was an old thread from 2017 - a while back!!!

Yes it was Joel's post I remember reading...His dealer said they had another one with the same problem??? I think I remember reading about another??? WHAT I'D LIKE TO KNOW, IF IT WAS CARBON, HOW DID THEY REMOVE IT WITHOUT DISASSEMBLING THE ENGINE???

PS, And I have a Stihl trimmer that needs the exhaust port cleaned of carbon periodically...I use only Stihl synthetic oil and mix it properly...larryd

The intake manifold can be removed and the engine crankshaft rotated to close the valves on a cylinder. The technician then can use chemicals, solvents, brushes and compressed air to dissolve and clean out the carbon before rotating the engine to do the same for the next cylinder. Again, my above explanation was not for small engines or two stroke engines. I stand by my statement as for modern fuel injected vehicles and will further clarify it to only add “in proper standard operating conditions.”

Your Stihl trimmer oil is the problem and not running the engine at a constant wide open throttle. There have been many reports of landscapers having this issue using the Stihl brand of oil. If I recall right they either switched brands of two-cycle oil or used Tru-Fuel’s pre-mixed fuel to resolve the issue. I purchased a new Stihl hedge trimmer and the dealer had me purchase a 6-pack of Stihl oil at the time because if I did I received an extended warranty. I have only used Tru-fuel pre-mix in the trimmer and the Stihl oil I use in the winter for my Toro snowblower and have yet to have any fuel related problems in either machine. I would not risk using the above mentioned process of chemically cleaning carbon in a two-cycle engine for fear of washing out the cylinder walls of oil and the loose hard carbon deposits possibly damaging the cylinder wall.

If you know what a MSDS is, here's what you're putting in your oil...
