Glad you finally answered. I've brought your name up in many threads in the past every time I saw you lurking at the bottom of the page.

Thanks for that.

Not as much as Nine Inch Nails.

Things are getting caught up around here and I finally tore into the 441 last night. I haven't degreed it or pulled the jug yet. Man, what a pain these are to work on! I have a pile of bolts just getting to the cylinder. This it's not a saw you're going to yank the jug in 5 minutes like most other pro saws. Anyway, here are some pics of the electronics. This is one carb I won't be messing with!

That does look way more complicated than the 576. It comes apart relatively easy. I think 5 bolts to get the whole carb assembly out.

I think it is amassing how something so small can control every thing,how do you richen it up ?.:cool2:

 

[blsnelling]

All it has to do is monitor RPMs and adjust accordingly.

I agree!! just from looking at both saws the 576 looked way easier to work on. Now the 362 and 261 are pretty easy to wrench on.

 

[parrisw]

So it only uses RPM to figure out fuel?? That's pretty crude if it does.

 

[Stihlman441]

Sorry guys but i think there is more to it that that,the only way to find out is do a port job for rpm lets say 15000 and see what happens,but i think you will be looking for a new cylinder after that.
Then what would i know i have just started playing with one.:msp_thumbsup:

Does the Wrap Handle and extra spike causing any difficulty when removing the bar and chain and/or cleaning.
Thanks..

 

[blsnelling]

It its just that simple, and quite effective. I don't have the link, but someone posted a doc from Stihl that explained how it works. It monitors RPM, then pulls a little fuel. If it speeds up, it figures it was rich and does it again. In this fashion, it constantly watches RPMs and adjusts the fuel accordingly. The result? A saw that's always tinged for max RPMs on the cut. Didn't get any better than that!

Why would it?

 

[PEKS]

Why would it?
It appears the wrap handle goes in front of the cover to access sprocket.
I take it, it does not interfere..

Sure doesn't.

If you really like half wraps like I do, then you will complain about the 3/4 wrap, but in all honesty it only adds about 2-5 seconds of time to a bar removal process, it isn't a big deal. Also you can't spin the scrench around, full swing, you have to do partial turns which is slower, but like I said, minimal issue.

I don't or can't use them because we cut a lot of lower stumps and honestly I have never seen the point in them for how I cut. I've tried them and they just get in the way. When I'm running a half wrap, I have never had a sudden desire to grab the saw in that location.

I CAN see the point of them for higher stumps and larger trees, as then you can cut with the bottom of the bar and dawg it in much easier, I don't routinely cut that big of trees with bars of 36" and bigger, so it doesn't matter to me if I use the top of the bar or the bottom.

I wish Stihl sold the M-Tronics or other higher optioned saws with just a half wrap. I always have to get the full wrap and then get rid of it. I have a pile of 441 full wraps that I need to get rid of sometime.

Sam,
Thanks for the details on the wrap handle, your explanation helps alot.
I haven't seen or tried the wrap handle yet.
I do not need a wrap, but many combos of the 441 M-Tronic model come with one.
Thanks again..

 

[Stihlman441]

If it costs you a extra $50 to get a standard handle so be it,all the other extras that come with the wrap model are worth it anyway.:smile2:
