I just bought the Stihl 361 and am thinking about doing a mm on it. Its a good runner but I am thinking about about jumping up to the Jon. 2171. Is a mm recommended for it? I havent seen anyone really write anything about doing that to the muffler.

what are you cutting ? is it for yourself and on weekends or for a full time job/work? the 2171 is a work horse by its self from the get go !!

The Husky 372/ JRed 2171 muffler is comparatively easy to mod and still have a stock appearance including a spark arrester screen. There is a bracket across the lower front of the muffler. Remove it and cut an oval hole in the bracket, then mark and cut a corresponding hole in the muffler. I don't own a dremel so I usually end up poking a couple holes with a drill and then using a file to shape the hole how I want it.

Once you have holes cleaned up, you can reassemble and sandwich a screen in between the muffler and bracket. This particular hole is a bit too large but you get the idea.

Rocky, after doing this, do I have to adjust any settings? I'm thinking about doing this to my 385.

The saw will flow a lot better so it will need a little bit more fuel. You will need to richen the carb adjustment a little bit. If the stupid EPA limiter caps prevent you from reaching the correct adjustment then you will need to remove or trim the tabs on the stupid EPA caps in order to adjust your saw correctly.

So, would I just adjust the high throttle crew?

My muffler is the same, right?

Thanks for this info, and especially the pics. Very helpful

I used the screw on deflector and screen from a Husky 288xp when I did the muffler mod on my 2171. Quick and easy, looks like it came from the factory.
Part #deflector 503 07 83-01 screen # 503 40 56-01
2 small sheet metal screws are also needed, #6 x 3/8 long

Hey Ed,
Do you have a picture you could post of you muffler mod using the 288 parts? Seems like I have seen one like this (maybe yours?) but can find it (I'm old and addled).

Yup, I've got pics now, didn't yesterday.

I did bend the top mounting flange of the shield to conform to the upper curve of the muffler. The shield is fairly soft steel and bends easily.
I drilled the new hole 1/2 diameter, with one of those uni-bit step drills, they don't grab on sheetmetal like a normal twist drill.

Do the jonsered and Husks keep dust off the air filter better then the stihls? Or as long as you keep the air filters clean then it doesnt matter? Right now i clean my filter after every time cutting.

For the most part, yes, Husky has a better system.
Newer Stihl models (441 & 361) do have a better system (similar to Husky) than older design saws (460 & 660) which require more frequent cleanings.

I do have the 361 and it seems to get lot of dust on the filter. On the Jonsreds and huskys do you not have to cleans them as much? and they a better saw then the stihls because they blow air off better?

Ed · « **Reply #12 on:** May 14, 2009, 11:35:22 am »

I'll clean the filters on my Stihls after every use, Huskys get cleaned when I think of it, in reality, probably, every 4th or 5th trip to the woods.

Are the Huskys better than a Stihl? IMO no, I still like my Stihls even if it does require a little more maintaince.

Each brand has it's good and bad points. A bad dealer will break any brand of saws reputation, so that has to be considered also. I'm lucky enough that isn't a concern for me.

I wouldn't give up my trusty 046 for a Husky, nor would I off my 2171 for a Stihl.

I've not had a problem with any appreciable collection of dust on my Stihl MS361. I shake it off (tap it on the workbench) when I touch up/sharpen the chain. Depends on what I've been cutting, and which way the wind is blowing while sawing.
Seldom do I get anything on the filter other than fine dust.

Not familiar with other saws, but would expect they all have adequate filters to protect the saw. Don't see it as an issue.

Ed · « **Reply #14 on:** May 14, 2009, 12:07:40 pm »

One of the reasons Stihl cam out with their "intellicarb" was to address the debris buildup on air filters.

Probably the worst saw I own for buildup is my 026. While it's a good saw, the air filter issue is a pita.

At last count there were 14 saws in the shop......subject to change.

It's easy to do yourself.

Just pull the muffler off and position the defelector, mark holes, drill deburr and reinstall. My 2171 was set a little rich, didn't need to readjust the carb.

still doesn't hit the revlimiter.

372 is the same as the 2171. main difference is the handlebar angle, Husky is angled, J-red is straight. I prefer the straighter one.
J-red doesn't have a comparable saw to the 576....yet.
