It's all his fault.
The venturi provides for the pressure/velocity differentials in the carb. Other than splitting the incoming volume of air into two columns, the divider has very little influence on that.
You'd think that to be the case but the reason I asked is because some here have stated an opinion that removing it does significantly alter the pressure signal to the jet to the point where it's near out of the range of adjustment...
Was considering getting a 241, but when Stihl made the Ver II 261 lighter, I decided to go with that. A lot more grunt for a little extra weight
I think you my be thinking that the talk of gutting the stratos refers to removing the carb divider as well.
CadAfter 13 pages how is the biggest mystery the internal workings of mtronic and no one has asked how come Mike - after years of telling us that the lightest saw you'd ever need is a 10mm 044 (or maybe a 362) - has bought a 261.![]()
Mtron good. Upsidedown divided intake trac good.I am still waiting for this.![]()
CheaterI've been using a popup in a couple models too....
Hahaha
Skipped tldrI believe you are mis quoting me, and have not been following recently.
If you can only take one saw with you, the 60 + 70 cc saws are the most versatile and can do anything, I will stand by that. My 60 + 70 cc saws are my work horses and get the most usage.
However, have you not been hearing my comments about my MOFO 026 Lightning Limber??? Love that little saw for the limbing duties, and now it will have a "partner in crime". The small saws are also more convenient to take along on the ATV. Was considering getting a 241, but when Stihl made the Ver II 261 lighter, I decided to go with that. A lot more grunt for a little extra weight.
I have been re arranging my saw portfolio, in an attempt to have 2 saws in each size from 50 to 90 cc (I count the 77 cc saws as 80 cc). I like to have a back up for every saw in case I rock a chain, etc. I currently have 3 066/660s, but one of them is spoken for. Since I have the 90 cc saws for milling, I sold two ported 77 cc saws (still have 2).
Stop making your head hurt. Buy a helmet soon!While I get what’s going on in principle, I still have a difficult time getting my head around how it determines (what they term as) the ‘desired operating point’, based on RPM only, without knowing the throttle position.
I see how it makes the changes to get there, just not how it knows where that point is.
For instance, how does it know when to idle rather than finding max RPM under load?
(EDIT: Oh never mind that example, just occurred to me it's got minimal air coming in at closed throttle, so of course adjusts mix/adv accordingly. Duh. This stuff hurts my head...)
Some of the terminology in the patent was cracking me up, The ‘rotatably supported’ crank and ‘pivotably supported’ throttle plate… Is that stuff standard patent lingo or a bit of creative translation from German?
Some of it sounded like a lawyer rewriting the bible. Lol
Thanks for considering my lungs as much as the saws.I think you my be thinking that the talk of gutting the stratos refers to removing the carb divider as well. I've nixed the dividing in the boot, and the jug, and even in the air filter base yet left the carb alone.
On both the 241, and the 261 there are gains to be had from doing so. The idea of such a radical change from the original design is not something I especially like doing though. I like the idea of using fresh air to purge the exhaust. I like the idea of less hydrocarbons in the faces of those that use these saw daily. So.......I look for ways to keep the design intact, and get solid gains. At the same time, I see no good reason to discount what anyone else decides is the best course of action.
You can bet I'll be doing even more testing and that I'll be trying new and different ideas........never should we stop trying to learn.
Tell me why? Sell me B-rad. What are the differences and how close are they after B-radification? We are cave men so you need lots of pics see...You still need a 241. With B&C and full of fluids, the 241 is a full pound lighter than the 261 VII. After porting they are a little beast. I sold my new 261 and pick up the 241 before my 346.

Randy, if you want this in a different thread, feel free to remove this.
BTW, if you want one, you'll have to get it from Randy![]()
And that is @blsnelling fault for sure
That damn Brad.....
Bastard
It's all his fault.
He's a sum *b-word. LOL
Bring the info here too. I dont go there anymore. Are you going to give away the build as in the timing numbers in the port work you did to it?
You can keep your secret pics of the grindings.
That saw flies.
If I get one mines only getting a muffler mod for now. So how does your 241 stack up against the 261 with just a muffler mod?
ExactlyYep.

Don't be skeeredI looked to page one. You gutted the stratos. I'm not building a gutted saw but Thanks.
