good point, i'll keep an eye on it, tbh don't use it for anything big, 560 or 660 takes care of that

You guys are doing some nice work modding those one piece mufflers. I have been working on some ms 361's. The muffler on that saw is very restrictive . I recently gutted one muffler which basically meant cutting the muffler into two halves . Getting it back together was a big pain . I also added a second exhaust port. I have another 361 ready to go back together . I would like to do another muffler mod just by adding a second port . I like what I see here . Much easier just adding that second port verses gutting the muffler.

LOL. I'M curious to see if 261cm loses any with larger outlets.

Which deflector did you use here? Looks like it is sized perfectly for the 261 muffler.

That is one of Joes smalls.

Deflectors are good on true worksaws. Nothing worse than turning the saw on its side and having hot exhaust blast your hand or face.

So I'm finally getting around to doing the muffler mod on my NON mtronic 261. I cut the gills in the left side of the muffler, took out the screen also. Is there any more that should be done?
What's the consensus?

I have same mod on mine and took screen out adjusted carb. Runs great

Shark gills

Allows saw to breath in clean air while at WOT. Lol

Hello,

I made a simple muffler mod on my 2011 MS261 carb.
Opened up the exhaust with a 13mm drill bit.

Tuned the carb, runs great. It's my firewood worksaw...
Need a rebuild tho, I'll open a post about it.



Aluminum color anti-rust paint, supposedly withstanding 600°C after being cooked at 350-400°C in oven.The original metal treatment started to rust.
