Mastermind Revisits The MS261CM Type II

[MustangMike]

That saw sounds strong, can't wait to see how it likes square file!

 

[Mastermind]

Here ya go......

you all might be right, or you all might be wrong. idk

what I do know is that you all is nuts

Ya made me laugh!!!

when we run the 661 with long bar in big wood it runs at about 9,000 rpm. when we run it on short bar it runs abut 12,000 rpm.

the saw must know which bar it has on it.

Lol. Too funny. [emoji106]

It remembers 3 different bar lengths, and ....

I always heard it took one to know one

Sounds like the guy that told me his 318 Magnum powered Dakota goes into a lumpy idle at stop lights when another car pulls up...

@Mastermind Great sounding and cutting saw. That sealed the deal for me deciding which 50cc saw I'm getting next.

 

[ABarrick]

.325 or 3/8 chain?

 

[MustangMike]

Dull .325. The saw will be running 3/8 square after I get it.

It took a lot of R&D work to successfully reliably implement Mtronics on Stihl saws. I think the nuts & bolts of the system is very simple. Stihl is fantastic when it comes to marketing, they make the system seem far more complex and smarter than it is. You read one of their brochers on the subject and think things are way more complicated than they are. BS baffles people, this thread shows exactly how effective Stihl's BS dept is.

 

[tree monkey]

complete m-tronic system, can someone please show me all of the sensors

Its all witchcraft I tell ya.

Wow, I expected to see the manifold divider to be removed at least.... Is the divider in the jug removed, or partially removed? Or is the strato really left 100% intact from end to end?

 

[tree monkey]

it's all there, 100%

 

[Lightning Performance]

Had to turn up the volume and rewind. A real PIA I tell ya. I'm like wtf is the hill billy rattlin on about?? He said Baa Baa Bawaa!?

Yeah........I know I'm hawt. What about that saw?

Hawtsaws wit lota nanas

They can say anything they like. lol

Just buy another legislator......

Step right up and be bought today! Crooks...

TROOF!

^x2

Is there any better answer than Ice Cream ?

I do not know how MT works but what I do know is it's an open loop system that uses programming to adjust jetting and possibly timing from what I understand to make the saw run in a range that engineers deem desirable.

Now, having higher velocity through the Venturi will create more vacuum which will help deliver fuel and atomize it better. This comes as a reward of the divider. The saw still runs so the same amount of fuel is being delivered as it would without the divider in theory. The quality of delivery (higher DP) and ultimately atomization as it leaves the jet in a ultra fine mist can (again in theory) allow the use of less fuel to get to stoichiometric.

Think of high pressure fuel injectors, it's not always about volume. It's more about using vapor pressure to your advantage.

The simple non horseshit version is a divided carb runs better at all RPM and the same as no divider at WOT. Easy peasy, ya see now? What he said^ and the low pressure pocket the divider creates is how it all works. Clear as mud right?

Ya made me laugh!!!

That why we come here some days.

when we run the 661 with long bar in big wood it runs at about 9,000 rpm. when we run it on short bar it runs abut 12,000 rpm.

Nice!

it's all there, 100%

Nice x2 Why *f-word wit it? agreed

 

[retro]

it's all there, 100%

Thats incredible, thank you!
