I run my 3400 Bow pretty clean...she likes to sing, but not so lean it lays over under a load

I run my older saws like I do my newer saws and ported saws... 40:1. No difference in tune either. Some saws like it richer, like my 262, but thats the saw, not the rule.
50:1, like most 2 stroke manufacturers recommend. And rich or lean is a function of the H and low adjustment screws on the carb. Today's 2 strokes don't smoke like the old Macs and Homelites. The 2 stroke oils today are much different than the old saws as well, your milage may vary. Oil threads suck.
All my saws get 40;1 and lean in the cut.
all i have is older saws , don't get used much minimum of 40:1
40:1 4 stroke no load like any saw. If it sounds lean n thin n screamy then it probably is.
The older Poulans were made to mix at 40:1 with good quality oil.As far as carb tuning goes ,never turn the hi side in more than 1 turn and you will be fine.I ran my old 3800 like that for 7 hard years with no problems until I backed over it with a tractor.Your carb may be a bit different,and altitude as well,but that 1 turn rule works most anywhere.
This works:
32:1 and run them on the rich side like all my saws - so they only clean up under good load, not when it just touches the wood.
Started at 50:1, went to 40:1 then 32:1.

32 is pretty excessive if good oil. Burns ya nose hairs against a big log. And running rich with 32 results in carbon build up and then a nice scored up piston
I politely disagree - the difference between 40:1 and 32:1 is 6 mls per 1,000ml’s, I can almost guarantee most people here who say they run a set ratio are probably over or under it by a few mls each time anyway. 6 ml’s of oil extra per L wont be the cause carbon, burning nose hairs and scored piston. A poorly tuned saw or cheap oil will. Happy to be proven wrong and if I ever notice any excessive carbon I’ll swap back, but so far it’s not been my experience since changing from 40:1 to 32:1.
never run them with less than 100.00 in my pocket 
Any less and it will sense weakness and need a carb rebuild!

I'm hearing ya man probably poorly tuned make the most difference.
I used to run 32 in my saws basically because it was what I ran all my life in dirt bikes and also the 82cc mccullochs ask for 32. Well after listening here I went to 40. Its motul 800 so very good oil and man what a difference. In the cut down in the bottom of a big log the fumes are actually quite bad and with 40 is pretty much unnoticeable.
A dirt bike with a pipe burns much higher temp much more load way higher compression under load and to be fair on the RM250 I've gone to 40 too. A 125 32:1 probably sweet as. A saw just isn't burning that motul properly hence the strong fume and watering eyes. At 40 it smells amazing like motul should.
Stihl oil stinks too I might add. Even at 50:1
How much you cutting these days Tom?
yes I used race motocross and 32:1 was all I used. Many moons ago now
I have no need for firewood, only ever collect carving wood so no where near the amounts others would haul. Generally about 1/3 - 1/2 a ton each year was what I would get through carving. Though with the injury that stopped for many months this year. So i have just been taking them out to go through a tank or two after rebuilds to tune and check them.
I’ve heard lots of people dislike the smell of motomix, I love it!
Far out I forget no firewood.
What bikes were ya riding? I just got back into it. Only RM250 at most meetings now damn strange. Usually a couple YZ250s lots of yz125s though and ktm 2strokes
What did ya hurt? I can't remember

I use to ride a 2001 Honda Cr250. I then sold that and got a cbr600f
I hurt my arm - tennis elbow.
Nice man
That will learn you for throwing the mega howler too much

‘Twas the bloody 056 Super that did it! Haha Something twinged after the second or third pull. Since then it’s been a constant ache, and sharp pains if I grasp something with my fingers.Nice man

Oil at 32 or 40 to one and four strokes WOT no load.
I ain’t happy unless I see smoke.
