STIHL Stihl ms441 non mtronic

[Jkstihl]

Does this look like a air leak or bad gas to y’all? I’m going to pick up a mighty vac but just wonder opinions? I have a spare 441c mtronic that has a good top end that got ran over so I’m going to build a 1 out of both. And tips or advice from anyone on here?

 

[Jkstihl]

Here is the good top end from the mtronic 441, what would y’all do? Build a mtronic or non?

Any words of wisdom from people that has built a 441 would be greatly appreciated

The cases are different on the mtronic and non mtronic saws. So you can’t really put mtronic parts on a non mtronic... and you can’t really put non mtronic parts on a mtronic. If that makes sense. Lol. That said you can swap just the cylinder/piston to make a runner. I would personally prefer to build it as a non mtronic as there is less wires and BS to go wrong on a already complicated saw.

Is there an echo in here?

Mtronic and non mtronic cases are the same on my 441 441c

I just used a mtronic case and top end that got ran over and put all non mtronic flywheel, coil, carb, fuel tank/handle on it. Here are pics.

Go home.

Go home.

How'd the pressure and vac test come out?

Hmm. Maybe they changed something on certain model years... but I investigated putting late mtronic stuff on a early model non mtronic case and it didn’t work out. This is the problem I ran into... https://www.arboristsite.com/community/threads/ms-441-m-tronic-conversion.323726/ I decided it was not worth the amount of effort. Easier to build it as a non mtronic. Which would be a more reliable build anyway.

Who knows what was really there to begin with and who had messed with it. You can see the different bosses for the wiring. You are not the first person who mentioned the differences to him, hence the echo comment.

Not MS441, but the only difference on the MS261 carb and MT is the area around where the coil is mounted. I went from carb to MT. Here’s a couple of pics, first is carb case, second is carb case “modified” to accept MT control module, otherwise there is no adjustment to air gap.

That depends on the point of view and the exact version of the saw. The cranckcase half (flywheel side) 1138 020 2605 is not used on the MS 441 C-M, only on some non m-tronic versions. The cranckcase half on the clutch side 1138 020 2903 is used on the MS 441, 441 C-M and some other 441 variations. It is also really importand to know which version saw you have on the bench to work on.

It was def a mtronic saw... wtf

 

[Jkstihl]

And I’m telling y’all they were the exact same I literally just tore both down to the case.

Carb baffle was slightly different, the holes don’t exactly line up for tuning.
