441c

[L34]

Hi gents,dad was given a 441c in a box today.It has been pulled apart because of a big cylinder and piston gouge.
Not sure why yet (pics to come later) but both circlips intact.Haven't checked bearings yet for missing parts.
Couple of questions

1) Is this saw worth mucking with?Don't seem to be a lot of love for the 441 from what I can gather.
Won't be using OEM P/C as too dear here in Australia.
2)If it has a black box on the carby with a black and a red wire coming out of it is it fuel injected even though it is a c and not cm?
3)Would it have to go back to Stihl after rebuild to be set up if injected.
4)Will it spark without carby hooked up.
5)Can i fit standard carby and coil?
Thanks in advance.
Cheers,Chris.

From some research it seems m-tronic saws had only the C on the starter.
Is the 441 and 441c the same cylinder?I believe they are but would like a reply from an expert.
Cheers,Chris.

A MS441C is a CM. Same cylinder on the standard carb version. There are no Stihl chainsaws yet on the market with fuel injection. It's just an electronically controlled carb. Great running saw, just a little more of a pain to work on.

Thanks Brad.Does the block on the side replace the mixture screws.Will have a bit more of a look tomorrow.Only had a 2 minute look over it today.Will put up some pics tomorrow hopefully.
May have confused myself with injection,used the wrong wording.
Never touched an mtronic before so just learning.
Cheers,Chris.

Exactly

So don't need any input from Stihl to get it tuned?
Would you put any money into this saw?
Most likely be AM P/C but OEM pin bearing.

If its in decent shape, the case crank and surrounding parts in good shape itts worth a china p&c kit. You may find someone with a good used topend if you post a wanted add in the trading post. Most all the china kits ive seen have very thin plating and just dont wear as long as oem. Unless you are using a premium kit or a kit with knowen good plating it hold off for used oem. Hyway have had very good plating on the few ive used. A list of obes id use if they even make a 441 kit is hyway (very good plating) meteor great pistons and usually decent timimg and port shapes. Then cross but sone have had some issues with them on other models.

Some pics.
My main concern if it has to go back to stihl for programming after rebuild.
Cheers,Chris.
Poor cylinder pic but is gouged all the way to squish.

I’d wait for a used OEM cylinder if that one doesn’t clean up and a Meteor piston.

Won’t be too bad price wise for the saw you will get.

 

[L34]

Thanks,yep cylinder totally rooted.

Not to doubt you but is the cylinder gouged or it has aluminum build up

BIG difference

 

[L34]

Very bad gouge.No aluminium transfer.

Bummmer dude......wait for a used one here and get it shipped.
You’ll be glad.

After the rebuild but before you run it hard, do the m-tronic reset to factory settings procedure.

I am looking into locally as in 5 minutes from my place atm.
Can get a meteor kit in Australia for $200,but not sure I want to spend that much on this saw yet.
Cheers,Chris.

You need to find out what came through the transfer and gouged the piston. Could be a piece of the big end rod bearing cage, so crank is no good if that is the case. Could be a crank bearing fail on either side. Also check the crankcase carefully. If a foreign piece got under the crank counterweight it may have damaged the crankcase. Check the carb carefully to see if a screw or some part came loose and went in from there.
That saw is M-Tronic for sure and can be reset without the MDG 1 scan tool. Probably posted here somewhere or PM me if you need to know how to do it. If you get it running, that is.

Thanks stihl#1.crank bearings,big end,pin bearing,carby all good.Case all good.
There are about 4 marks on the piston top that look very much like a plug ground electrode.Very square and straight edged.
No plug in the box so unable to confirm this.
I will PM you if required.
Cheers,Chris.

Missed out on OEM P/C.Bloke traded the saw at stihl, so he threw out P/C because plug thread was buggered.
BUMMER!

Hyway cylinder in Australia is $190,so only $10 less than meteor.
