Being an amsoil dealer and getting way to far into oil analysis then what is healthy. Your oil might have alot of non-combustable additives in it. 32:1 is also a little excessive I might go to 40:1. I run amsoil saber (I wonder why) at 50:1 they recomend 100:1 on the bottle and I have seen it done very successfully but im still not going to do it.
 
Yes. Maybe not as much, but still the same kind of carbon formation.


Shell Premium Unleaded.


I removed it right away.


No signs of heat on the bottom side


I think I like that idea, although I may cheat and go to 40:1.


I see that on the bottom of the intake skirt on nearly every saw I tear apart. Matter of fact, this is less than normal. Not an issue, IMHO.



For the most part. Always Premium Unleaded.
then you won't know the culprit....You were running 40:1 till last year, how were they then?
 
I don't know about the gasoline in Ohio, but all Shell gas here in Tennessee has 10% ethanol in it. Is that the case there? I get all my gas from a local store that sells a "no name" fuel...100% gasoline. I for one have no love for alcohol, ie water in my gas. I also have no idea about what happens when additives, ethanol, and 2 stroke oils are mixed. I will watch this thread closely to learn more about what's happening here. That much carbon in that short of time is cause for concern IMHO.
 
Ok, I'll bite....

Why 32:1??? I don't even run that in my Lawnboy...

All current saw manufactures say 50:1, especially running synthetic, your not milling, so why??

Like stihl boy said try super techniplate, you'll wonder why you didn't try it sooner. I run my equipment at 16:1 and don't have carbon build up like that.
