MS441 R C-M M-Tronic Review and Mods

[STIHLTHEDEERE]

I read somewhere that Stihl US had something like 600 460's in stock and they need to be sold before the 461 is put on the shelf.

Could be wrong though...

i know for a fact that there less than 400 in central ohio, and they are going a little quicker now since they are on the way out. i would guess there are alot more than 600 in the pipe line. besides it will be like the 440,no stop in production, just distribution in the u.s.

 

[CR500]

Lol absolutely not that's why I said it's what I heard and the sooner the better.....

Better get here soon... the world ends next year allegedly 12/21/12

Yeah it also ended on March 23rd 1997 for the 39 freaks of the Heavens Gate Cult.....

I don't think it could run too lean, it just keeps mixture at optimum where mosy saws are slightly richer that optimun. Combined with strato design, would like make a hotter muffler. Just my opinion.

I agree but the maximum temp rating for certification stays the same regardless of whether it's a strato design or not. I asked whether the stratos have a different temp rating but no they don't and from a bushfire point of view doesn't matter. To reach EPA standards though we do seem to be seeing a lot of factory saws set leaner than ideal lately but not saying this is the case here.

I'll check the plug after I run it in a few minutes. I can tell you just from the sound of the saw It's not running lean. IMHO one of two things went wrong withe the certification. One the saw was likely too new and didn't have time to adjust it's self, and two the exhaust can on any saw will get over 340C 644F so the test is pointless IMHO.

I can see what you're saying Andy but the Australian testing is certainly not pointless although probably less relevant to other countries with higher rainfall areas, different tree species, and different weather conditions. I asked a number of questions as to how this temperature level came about and it had a lot to do with ignition points in bushfires etc. Bushfires in our country, and in certain parts of the US no doubt, are no laughing matter. Many people have died here from things as simple as a car exhaust being too hot or a stationary engine catching leaf litter alight - they haven't pulled these numbers out of mid air. I'm glad you've said the saw sounds rich enough and I think it did too in the vids. What this test has said to Stihl Australia however is to fix the problem or any model of saw cracking the magic 340°c mark simply won't be bought by forestry or anybody other than weekend hacks and firewood cutters. Any bushfires started however even by a backyarder with a non compliant saw would really open a can of worms - the court case would be huge especially if property or lives were lost because of it. The saws tested were given a good workout by all acounts so I'd have thought they would have self adjusted by the time the test was taken. By the way I'm not anti M Tronic and neither were the testers - I love the idea
I'd also wished I'd had the 7900 checked as that has caught bark alight very easily, even my stock saws have when the exhaust port is jammed in against dry bark or leaf litter. Eucalypt is extremely easy to catch alight as it has a lot of volatile oils in it.
Also there is no reason why saws destined for the Australian market can't be tweaked differently to those in the US as although we share many emissions standards you guys do seem to cop it more than us.

Matt I understand about the heat issue and fire prevention. What I was really getting at is the exhaust cans on every stock saw I've ran to date, under load will get the muffler can red in spots. You can see this when it's getting pretty dark out. I guess it's possible to get the outside temps down, but that would likely mean extra size and weight. Do you know what part of the saw they're taking the reading from?

 

[Terry Syd]

If the temperature is taken off the muffler, I wonder how a muffler mod to reduce backpressure would affect the temperature rise of the muffler.

If it is one hot spot on the front of the muffler where the exhaust hits it, a simple baffle inside the front would absorb most of that heat and give a cooler reading on the outside.

Brad came town this evening and we ran the 441, 7900 and Brad's dad's stock 046 with DP muffler. I did tune my 7900 and it seem to help some.

Here are the times. Take into consideration not every cut is made simply for the fastest time, light load, medium and heavy.

Not bad at all, especially considering the 441 is still on it's second tank of fuel. That 046 has seen many a chord of wood and many gallons of fuel. I will add that I didn't notice the 441 hunting hardly at all. I'm not sure if it has simply "learned" or if it just didn't show as much in this softer Bass wood.

I Noticed it a little yesterday, I think it learned. Soft wood yes, but we still loaded the saws pretty good.

That we did, and the fastest cut times were those with a heavier load. It looks like you might have the opportunity to compare it to a new 576AT. After that, the 441 will go under the knife.

I was just going to post..........

A kind member from this site has offered to send me a new in the box 576-AT, he hasn't even bought the saw yet. If he chooses to come out and state his name that's up to him, nevertheless. Thank you!!!!!!!

 

[blsnelling]

Save some of that log for a rerun of the 441 after I port it.

 

[Officer's Match]

Fella's, thanks a BUNCH for doing this, including the-as-of-yet-unnamed-hero allowing the 576AT in on this, I couldn't ask for more (as I'm sure lots of others will say too).

I think the unnamed-hero needs some rep! and so do Andy and Brad :msp_thumbup:

no 460 video:frown:

 

[Rudolf73]

no 460 video:frown:

But there's a 046 in the video...

 

[WoodChuck'r]

$5 says the 576 takes it.

Another $5 on the 372xt. That saw needs to be part of this if it isn't already.



I'm an honest man and I'll pay if anyone wants to rumble.

Hey come buy a 460 Arctic and stop wasting your money on losing bets :hmm3grin2orange:

 

[Philbert]

B]19[/B] different parts needed to convert over to m-tronic.

How about the reverse? If someone had and M-tronic or AT saw that was messed up, damaged, etc. Could they convert it to a conventional saw by swapping out just the coil and carb, or would anything else need to be changed or removed on these saws?

Thanks.
