well before that, you'll have to pony up one more ticket for the raffle saw. You might as well do it already as you know the Husky's gonna get thumped. It's gonna be so sweet winning a Stihl on a ticket a Husky fanboy bought.:tongue2::hmm3grin2orange:



Hey FATDUDE since when am I a Husky fanboy?!


I think you've got me confused with yer boyfriend Brad er something!! :msp_scared:
 
I think the 576 will take it with a modded muffler. I may be wrong but I think it will be a little ahead with both having modded mufflers.

Did you guys ever run them together yet? I thought you did, but look around the 38 pages and didn't find it.

They ran them together a couple times so far. The first time the 441 was ahead by a decent amount. The second time they were within a half second. I guess the 576 gets a 3rd shot at catching it. Andre still has the saw for now. Whenever they get done testing/playing and Brad wants to port the 441 then I'll get mine shipped to me.

LOL, so the muffler modded 441 did beat the non muffler modded 576, by more at first and then less the second time? What changed? How many tanks are through them, because the 441 isn't going to cut worth a hoot until it has some say 15 tanks, I say 20 tanks. I'm sure the 576 is similar.

So it will be interesting. At this point is sounds like its going to come down to a couple seconds or less, and that just doesn't do it for me ...... win or loose by either one.

Are you guy's going to modd them both and then run them again for fourth race?

Sam

both will be compared with muffler mods
 
I found the times of the 576 and 441. What does it mean when they say, they timed the cuts, but weren't racing? Are the times legit times or just fooling around with them, which times are which?

Just wondering,

Sam
 
What do you use the Tacho for? Is there something to adjust the tune with on the 441cms?

Hi, It was bought because it is used on our old 440,460 and 660 saws as we have being experiencing "bad fuel" probs over the last 15 months/2 years 's or so. We bought the 280i's because of this and had no probs at all. The big saws were getting worse and we thought this was wear and tear. Because of this and issuses with our old FS450 brush-cutters, we bought 1 441cm and no probs! so on that saw over 5 or so days, we upped the bar from 20" to 25"- did 5 consectutive cuts,stopped it, restart and different saw! so we did the same with 30" bar and same! Awsome power but big difference in fuel ie uses more - alot! Because of this I bought 7 more and they all run perfect. The tacho is used to tune the old 441 carb saws max revs on the big bars ie 30" etc. It is an acoustic one so you can set the paramiters to how you want to - so stopping over reving with the fueling etc. Fuel and emmissions are a major headache and so is wrecked saws so it serves a purpose for the older saws that are having to run on awful petrol! It works as we have found 6 out of 5 saws-the rev limiter was 900 -1500 rpm out!! ie under reving!
 
Well I hope the husky wins since its mine. I don't think either is a bad choice.
 
I've had my Stihl MS441RC-M since Jan. 26th, 2011. Picked it up in Ohio. (northeast)

It was the first one in the country with the M-Tronic sold to my knowledge. And in the Full Wrap option. It has just taken the non-believers in a 441 and then the M-Tronic to catch on.

It also has been fully ported since the first of June '11. No problems so far and the blueing on the outside of the stainless muffler is pretty cool looking!

I bet the 661 will be accepted much more readily.

Which form of mm did you go for out of interest?

Sounds like a serious bit of kit. What did you do to the under reving saws, swap out the ignition modules?
 
ITWA Im sorry but I cannot grasp the problem you are having with " awful petrol " you are in Nth Yorks not Nth Tibet ! do you mean that as with all unleaded it is "going off" if that is the case then try Briggs & Stratton fuel fit it works very well.
In an earlier post you stated that it was "illegal" to use more than a 25" bar on a 441 in the UK I assume that you were refering to operators that have not compleated the NPTC CS modules required ?
The vast majority of members here are based in the USA so our, European, practices are worlds apart and we seem to be quite lucky in the fuel issue compared to the nightmare of additives they have to suffer !
