Interesting finding pictures of a demo stihl 461 floating around on the internet in a search of new saws today. Suppose to be the replacement of the stihl MS460
-
Looks like stihl is going with the single barrel intake like the 261. Hopefully it will have more power than the 460.
-
Have had these for awhile now, just forgot to post them here. Someone had posted some more 461 demo pic.
Looks like a arctic version.

The original poster of those pics got into trouble with Stihl! ::)
-
Bump for a member looking.
-
Thanks for bumpin!! I'm curious of the hp and what the AV is...any idea?
-
I hope they do it like the 441......single barrel stratos ain't the way to go......
-
My only experiance with this type of technoligy is with a 441 .They seem to do okay but you have to run them about a minute before they warm up well enough to run right . If you cut a little and shut it off you have to go through the same rig- a -ma- roll again before it acts right .That kind of annoys me .

I've never thought about that Al. You are right though, that would be aggravating...

TreeworkDK = Just out of interest, the 460 is up first and has 20" bar 7 pin sprocket the 461 has 24" bar and 8 pin sprocket. Timber is Contorted Pine and is freshly felled and is very wet.

I'm looking forward to seeing the 461 on my bench under the knife. :)
-
might have to save some coin and get one ;D
-
Those saws weren't MS461's, but test beds for some new parts.
They were testing out the air filtration system but the rest of it was all MS460.
If Stihl is going to sink 100's of millions of dollars into a new model they do a complete ground up new
model, and not an upgrade of an existing platform.
-
Cale the cylinder has the decomp mounted over towards the side. Is that the cylinder design they're going to use on the 461? I hope it is spring av like the 441. I might be able to run it for more than a few minutes without my hands going numb.
-
I know of a 461 being field tested as we post here.
Thats all I can say and dont want to ruin my insider info link. ;)

Another pic floating around.

No!
The MS461 does have a 2mix engine but it is not like the one in the video. No twin butterly valves or MTronic ignition.
Unlike the others with fresh air stratified charge the 461 has the it off the exhaust gases.
The new ignition module has a speed limiter to keep rpm within 13500.
The new carb is very similar to the one in the460 except for the different jet sizes and a dual lever for the choke.
It is very much like a 460, but with quite a lot of differences.

Guy says they are in Ontario Canada for sale now. Stihl 461
-
I would like to see inside the cylinder to see how it is built , I know I'm different but I like the single carb setup better than the duel butterfly setup , just less stuff the wear out down the road plus it makes getting fuel into the stratos ,

I'm with you on that one. Prefer the 372xt style. Besides its easier to add a little mix to the strato if desired.
-
Heck, I just want to see a video of a stock one that is broken in a 24-30'' log against a 460 wearing the same bar, chain and rim for comparison myself. This is the only REAL subject that concerns me is the power it makes vs the older version the 460. If the power is at least even and uses less gas then I would be interested. The AV does'nt bother me, I've swung a hammer and nailgun my whole life and we all know there is'nt much AV on them so this makes a rubber mounted saw feel like a Lincoln to me. Besides I'm just a firewood guy with a bad case of CAD... ;D
-
I'm only guessing but I would think the newer design will be stronger as it will make more torque with the stratos ,
-
It's a rubber AV non strato saw*.
*Unless they have made a strato saw with a single intake throat, single butterfly Walbro HD
carb, traditional windowed piston, and no extra strato ports.

Sounds good for us old school guys. Bet that is what they are thinking as far as the market.
-
then its not stratos , I have seen no pictures of anything inside the motor , so its pretty much a 460 plus the number 1 added to it
-
After studying the IPL it looks like they changed the air intake system (rewind, filter, filter cover, cylinder cover).
To allow for better separation of dirt from the air going in the filter, I can't tell if it's the Husky style air injection or not.
It looks like 75% of the parts from the 460 will fit the 461.
It shows a traditional windowed 52mm piston and single intake cylinder not sure if its got 2 or 4 ports
-
This sound good to me, at least there will be some old school left in stihls line up. I do hope it has 4 ports though.
-
The 461 is officially out there ! I just received a paper from stihl announcing them at 1029.99$ . My dealer confirmed me he ordered some and they should be there soon . Of course , i'm in Canada :P Probably the first time we get something before the US ???
-
They have been sold in TN dealer for a few weeks now too.
-
Still interesting as we always get new models a couple months later . No dealer here are even aware the 346 will be replaced by the 550 for exemple .

Thanks for bringing these here Kevin. I just don't have much time right now to post a lot....
-

According to my Stihl literature it is has a "low emission stratified charge engine with delayed stratified scavenging."
-
Would that be quad port transfers???
-
Yes it's a quad port.

the saw randy has is mine,and the photos above ,i found this site when googled ms461 ,saw some user names i knew so read on ,looks like a nice setup here ,this saw will be getting modded after randy catches up on some customer saws

-
So if this is stratified scavenging, were is the fresh air coming in?
I see no way for air coming in unless it go thru carb??
To me this looks like a normal engine with transfers in front...
Another thing that bugs me is the ported piston and cut outs in case for trancefers in side, but no in cylinder?!? Why is piston ported?

Magnus the fresh air comes in through the exhaust port when the piston is TDC. Look at the cutout on the base of the exhaust side of the piston.
-
no, there is no fresh air, or egr system of any kind on this saw.
thay simply improved the porting to pass epa
-
Well I guess that settles that :-*
Not having the 461 in front of me to examine, I just had photos to go by...............I took for granted Magnus was onto something ::)
-
I can not see anything different than a conventional engine other than bracket.
The partly burnt fumes going back is nothing new, it is in the principle of the engine.
The thing that stato and X-torq etc do is let fresh air out in muffler last so that is sucked back in.
From the pic's, this engine is a normal engine as far as piston and transfers go.
Front transfers is not new, just disregarded on saws as the distance and time it takes for the fumes to travel was considered too long.
To shorten it it required higher pressures and faster flows... Used on other two strokes, but never worked well in saws due to temps and fuels...
-
FWIW if you look at Forestry Forum Joe from India had some pictures that were a little clearer and some other items shown .It became a lot more clear to me after I saw those pics .
Once you see them it should clear a lot of things up or at least it did for me .

Told you guys on page 3 it was a strato saw, just a different approach. Getting a GS461 to demo this week. Have a sale for 1. $2350 plus tax. Saw motor as a 461.

$2350 oh my heavens . . :o

Old Iron Logging.
Please explain to me how it works technically. Not the marketing/sales talk, I heard that already...
I looked up these animations, thought it could be fun for some to see..
Stratro: http://www.youtube.com/watch?v=3LDN0c2lAsQ&feature=relmfu (http://www.youtube.com/watch?v=3LDN0c2lAsQ&feature=relmfu)
X-torq: http://www.youtube.com/watch?v=IY7zQKw4qsQ&feature=related (http://www.youtube.com/watch?v=IY7zQKw4qsQ&feature=related)
Conventional: http://www.youtube.com/watch?v=LuCUmQ9FxMU (http://www.youtube.com/watch?v=LuCUmQ9FxMU)
Conventional: http://www.youtube.com/watch?v=xV9jnWVeSB4&feature=related (http://www.youtube.com/watch?v=xV9jnWVeSB4&feature=related)
Intake port on a two stroke can be regulated by a valve and be located pretty much any were bellow exhaust port.
On most saws the valve is the piston and its skirt that determine when it is open or not.
Same with the exhaust port.
Fuel air mix is let in crank case under piston, flushed up thru trancefers above piston and ignited. As they expand piston go down creating the power.
How the transfers are formed and located is not very important really. They serve same purpose regardless.

This does not help me see were this is different other than longer transfers.

Wasnt for you ;) was for Art. Just thought it was pretty awesome video showing the cutting of the concrete saw he was talking about.
Me I could care less how it is, as long as it starts and runs when I would want a saw to.
-
Magnus, when the boys get done with the 461 at tech school this week I will have more info for you.
-
Sounds good.
-
Looking at the images that Cut4fun has posted, could someone try and explain the reason for the clean crankcase and the not too clean cylinder and piston.
In the one I tested the piston and cylinder had the same appearance.
Joe
-
Any news on this Art?
-
I hope to get an answer this week.
-
The 461 must be a national secret. The boys don't want to talk about it for sure. All I have been able to get so far is that it is "Stihl corrected Husqvarna strato technology" and " it will not work on a motor under 50cc ".
Will keep trying.
-
Just read this.
MS 461 with a new OEM jug and piston. It was not over heated lost the piston when a dampener behind the piston came lose and hit the piston.
I remember something in a past pic, but trying to figure out what it was.
