Seeking The MS400.1

[Rich Fife]

I have a real nice 2065 I need to change the crank in lower rod bearing let go.

That's a nice Saw! I have a 2077 that I'm missing a few parts to have it complete... Chain brake stuff and I think an oiler or a sleeve for the crank/seal??? It's been a while.

 

[Rich Fife]

Isn’t a 381 cylinder and open transfer saw with bigger squish for poor fuel in certain parts of the world?

I will run a 16’’ bar on it and the C85 chain.

Going to be some confused people now, first saw with mtronic and intellicarb wrapped into one. I’m wondering if Stihl screwed up though and this is supposed to be on the ms 363 since the carb looks to be standard adjustment. But in the 400.1 description on the Stihl uk site.

This generic picture just illustrates more or less the principle of this feature. You will find it everywhere in the descriptions of saws that are equipped with it, starting with the MS 170 or MS 162.

Generally, Stihl chainsaws with M-Tronic are classified as having a compensator. MS 241 & 261 as an example:

Pretty sure the 362 or bigger mtronics don’t though.

 

[Duane(Pa)]

Maybe it should say compensated, not compensator? MTronic compensates for everything under the sun with precious few samplings or parameters.

If you believe the information on Stihl's websites about the presence of a compensator in the MS 400.1, you would probably have to agree with the pages about the MS 362 C-M or other “big” chainsaws reporting its presence in them.

MS 362 C-M Petrol Chainsaw | STIHL

Robust and powerful, everyday forestry chainsaw, designed and built for the professional. Ideal for long sawing sessions harvesting wood. With 2-MIX engine and M-Tronic technology. The electronic self-tuning engine management system means that the fuel supply is electronically controlled and the...

It all depends, of course, on the definition of compensator aka IntelliCarb. And indeed, in some catalogs Stihl does not state that IntelliCarb exists on saws with M-Tronic.

Personally, I'm almost 100% sure that in this respect the MS 400.1 is no different from other saws with M-Tronic.

I also believe that the determinant of whether a particular saw actually has a (true) compensator should be where the outside of the metering diaphragm is connected. If it is connected to the air box (behind the air filter) and subjected to the pressure that exists there, then we are dealing with a compensator.
I think this is the case for MS 362 C-M and the current MS 400 at least.

Update:
Dealer said delivery off the first saws will be may.
He gives me a price a soon as they are available for him

 

[lehman live edge slab]

Just kinda trying to guess USA price but looks like it will be above the 362 but not a huge amount if the numbers here stay kind of the same for us as the uk.

 

[FederalQ]

That equates to about $1,269USD excluding their 20% VAT for the 400.1

But that’s compared to the 362 which is 870$ here find it hard to believe the 400.1 will be more than the 462. I’m guessing just by these numbers the 400.1 will be 925 or so in my area

So can we assume that the new 400 (400.1 to be exact) will be cheaper than the current mag-piston-400 ?

If so then that will be somewhat of a win. I have the current mag-piston 400cm and it was 1360cad roughly before taxes. So if the 400.1 dropped closer to the price of a 362 then that would make it a fair bit more affordable and create a better price gap between it and the 462.

Looking forward to seeing what can be done with them and how they compare in the real world to the OG 400

Welcome to OPE.

It's a been good. I've been lurking for awhile but I've been collecting saws recently and will be using this forum to get as much help as possible when doing mods to my saws.

.... I may have missed it but is there a thorough DIY thread on how to do a timing advance?

Not to derail. I'll likely collect the 400.1 once it's available hence why im following this thread.

Cheers!

Thank you!

ms363(the manual carb version) seems to all over south america and eastern europe already based on all the youtube videos with it.

 

[HP Ultra]

The MS 363 is NOT the manual carb version of the MS 400.1 C-M
This is a fact you all should keep in mind

MS 400.1 = 2-stroke 2-Mix engine
MS 363 = 2-stroke engine ( no 2-Mix )

i.e. you won´t see the MS 363 in regions with higher emission standards like EU, USA, ....
