New Saw Update

Redd,
Took you some time to get the "work smarter, not harder" concept with your saw--now when you gonna get it with the splitter?! %-P

Glad to hear it's workin' out for ya!

With that mix: not sure you needed to even show up.

"So here’s the update: a couple weeks ago I fired it up to cut back some shrubbery at my parent’s church (they are protestants). The saw ran perfectly."

Do you think the saw might have done poorly, had they not been Protestants?

As many, if not all, of you know I purchased a brand spanking new MS440 last summer. And with it I proceeded to cut up about 10+ cord of wood - mostly Doug Fir and bigleaf maple. I've run it exclusively on AvGas 100LL mixed at 40:1 with Royal Purple TC-W3. So here's the update: a couple weeks ago I fired it up to cut back some shrubbery at my parent's church (they are protestants). The saw ran perfectly.

Just thought you'd all want to know.

Why 40:1?

50:1 will leave less residue on the transfer ports and will be plenty of lubrication especially with 100LL

I run 40:1 also. If your leaving residue (btw who knows or even checks) on transfers I would think your running too rich. The plug is your indicator of cylinder health. What I see from my mix and 100LL is a perfect antique white too very light tan and plug is clean.

But when you pull a cylinder even with a clean plug there is usually a difference in carbon buildup on surfaces from using 40:1 versus almost one at 50:1. Of course some of that is the oil you use.

You should check out Bsnellings posts on the subject on arboristsite, it's pretty informative.

I used the remainder of my Racing 2T this year and need to find something new next year

you cut back shrubbery with a 440? Isn't that kinda like traveling to the Dollar General to get a Half-gallon of milk in this:

I kinda thought that too. However, so many people ask so many saw questions that this update was needed.

What ratio do you use for shrubbery being circumsized at synagogues? :smirk:

I'm pretty sure any form of lubrication is a sin for us Catholics. Friction = suffering and that brings us closer to God.

I don't know what that means for chainsaws, but there's a good reason school uniforms needed to be long enough to cover knees+elbows.

Ba hahahahaha OK OK stop already. My sides hurt so bad I can't even breath.

Why do you use Avgas in it? Any special precautions since there's lead in 100LL?

I assume it's because no ethanol or automobile additives?
I've never heard of people using it in saws actually.
Do you run it in anything else? tractor, splitter, etc...?

is $6/gal worth it compared to the $4 for mogas?

100:1 of course. Use far less oil that way. ;-)

Many folks swear by AvGas because it is designed to prevent storage issues, has no ethanol, and has a high detergent content relative to auto fuel. It does indeed store for long periods of time so long as it's kept cool and in the dark. It's usually recomended that it be stored in metal containers.

Be aware that AvGas has up to 2X the TEL (lead) in it that auto fuel used to have. Something to think about considering the equipment you'll be running it in generally exhausts in your proximity, is not a fast-moving enclosed vehicle, and follows you around.

AvGas is very popular as a 2-stroke fuel for ATV's, Dirt bikes, Saws, Snowmobiles, etc... Mostly because of the storage benefits and no risk of incompatibility with rubber parts in the fuel system. You could run it without damage in anything that's not registered for highway use, doesn't have a catalytic converter, and doesn't use O2 sensors. Trouble is it's kind of a grey area selling it for non-aviation use.

Worth the $6 a gallon? Up to you and depends on how much fuel you'll use, how much of a hassle is it for you to get, etc...

I don't know about that, but I'm pretty sure Brazilians skip the oil entirely and go with 100% wax for removing shrubbery.
