It looks like a 362 on the outside but I bet it looks more like a 261/462 on the inside. Id bet they ditched the dual butterfly setup and went with split Venturi carb to simplify things and keep weight down. Slightly bigger crank, larger piston and cylinder and voila, ms400.

So your picking up your 462 tomorrow I hear[emoji16]

Hi Evansaw,

I don't want to doubt the source of your information but it astounds me that Stihl does not continue equipping its professional chain saws with fuel injection to underline its position as a technology leader. Certification of new chain saws in line with new EU emission regulations becoming effective this year suggest that fuel injection would facilitate to fulfil new emission standards due to its numerous parameters being sensed and the exact amount of injected fuel calculated in real time thus reducing raw emissions. For this reason it can be assumed that Stihl will continue with fuel injection in the long run. It seems to me that the mentioned 400 c-m is carved for a specific market niche in the interim.

It seems like Stihl is being super careful on the DI... spend years on their cutoff saw, now going to chainsaws... After some time in service they'll probably add more models. I wonder if the DI module and fuel pumps scales in terms of weight...

Not exactly direct injection. The injector sprayes into crankcase. The new sleds i work on have true 2 stroke DI. High pressure injectors that cost a ALOT

On the TS500i the fuel is injected in to the crankcase.
On the Chainsaw they inject the fuel between the intake boot and the cylinder.

Man, I can't get away with anything lol. Not sure yet actually. I have a carbed one showing up sometime this week from Greece but I'll more than likely end up with an mtronic one too. So I can compare them, for the good of the community and stuff.

Nice! For the good of the order! [emoji16] [emoji106]

I am very interested in a carb vs m-tronic comparison, brown plug vs black. Wondering if there will be a significant fuel usage as well as power difference. On another note I hope the ms400 has decent sized gas and oil tanks.

So say we all

I'm more excited to see this than the 462

Looks like the 67cc MS400 C will be replacing the MS362.
Anyone know what that black knob on the back of the top cover is all about?

Another view of the knob.

I think Stihl put that device on all their demo saws. Maybe for tracking or so

Yes I was thinking that too, some kind of GPS anti theft setup .

 

[Stihlms]

Exactly

Cool! Put a 361 coil on it and have full rpm range.

The MS400 is a CM

So you can just pop the cover off and toss it into the back of a out of staters pickup.....hmmmmm sounds fishy...speaking of which were is fish? Lol.

 

[ManiacalMark]

And? You could most likely take a 362 non mtronic carb and retrofit it on.
