3-5/8 turns out on the H is maxed out. Your carb should never be set there
Thanks Deetsy...that seemed way out to me also but I didn’t know for sure if it was bad for that particular saw.

Hi Deetso66
The specs do read 3 5/8 turns out on the H, this is to bring the WOT to
12,500 or just below,
Then the Idle is set to 3,500
Then one turns the Low out from 1 3/4 turns until rpm drops to 2700
Then tune the H to suit, but there is a conflict, I found another spec that
States 13,000-14,000 quoted as Max WOT.

Not sure what to trust now, I think I will try for 12,900 WOT,
but am sure the L won’t like it and unless I screw it out I will be back to
the slight misfire, oddly no bog down, but I guess the H Is delivering
more than its share.

The only thing altered was the muffler, and it is no where near as much as others have done, so am blaming it.

haha that's what I said when I pulled down my pant
I hope mastermind chimes in, my settings were 3 1/2 turns out, and I knew they were rich
and would need altered, so I put them in and turned out as echo suggested,
It made the saw slow, I turned it in and the saw picked up revs as expected,
It’s not as nippy as I had it by ear, I had more fuel going in the L and it was shap
acceleration and no backfire on deceleration, it’s not as sharp now but no bogging either.

I would start with the H at 2 turns and tune it from there. If the saw is racing at idle or has a big when blipping the throttle richen the L side until you achieve a good sounding idle.

Hi XP_slinger
I took the saw to the local saw guy, I explained that this morning it took four pulls on the choke after which she started.
I told him the H setting according to echo, he said way to rich.
Then he proceeded to seat the Low screw, and said 1 1/4 turns out was about right, he started the saw, and backed out the Low some more, the chain was almost turning so he cut the idle, he never touched the H jet at all.

The saw sure accelerates and to me is running rich and probably below the
recommended WOT numbers.
He does not use a tachometer.

Half hour later I was home, the saw needed one pull on the choke to start,
it was not cold, the Low is richer than echo spec, and yet it needed choked
and it not cold, this seems wrong, I will let it sit now and see how it starts
When am sure it is cold.

That is the procedure I followed.
I don’t recall you mentioning the final high side tune of 13 to 14k in the procedure. Thats why she wasn’t running right for ya.

With your low side rich it would’ve likely started with the fast idle set but with choke off. Sounds like you need to lean the L some and then readjust your idle using the idle throttle stop

That’s what I needed to hear, I am going cutting small bushes that are too heavy for a hedge trimmer, that is why I was staying away from a fast WOT setting.
I told the saw guy Imwent to that the WOT settings were too low,
He did not adjust the H to fix this, I mentioned it twice ,he said she sounded right.

Crank her up man, you’re not going to hurt it by tuning it properly. Don’t let the tac numbers scare you away from a good tune.

I upped the idle slightly and still need two pulls on choke to start, the engine is not yet cold.
Regarding getting to between 13,000 and 14000, it was proving impossible
With the Low settings echo gave, as when I rich ended up the low to achieve the idle echo specked, there was that back fire to deal with, I richended up the Low some more to fix that, then the idle would not go down, so I could not figure out
whether the idle or the Low was out, because they were not adding to what echo
Make out, so I left it, and took it to the saw guy, and now it’s hard to start even though it’s not even cold.

Crank what setting, As the saw needs two pulls of the choke to start when not even cold,
this saw guy seems to have made matters worse. So will leaning out the top
also make this / starting worse, that’s where am at now.
I think I need to richen up the bottom a bit,
Reason, if I lean the H am not going to be fourstroking much if any
and that concerns me.

Thanks for commenting

Start out at 1 1/4 turn out on both screws. Turn in the L until it goes lean then back it out 1/4. Idle should be around 2800. Set the high 12,500 then fine tune in the wood. If it doesn’t run normally after that then you have a problem.
