Lakeside53's --361 muffler mod w/photos

[Lakeside53]

Cool, thanks lake. Hey do you have to get new covers for the two screw holes?

nope... I also added to the orginal reply to your post..

 

[Lakeside53]

Oh, and are the 16mm screen and clamp usually stocked items or special order?

Your dealer probably won't have them in stock as nobody ever replaces the TS400 screens! We get ours overnight though... like almost every stihl part.

My 5/8" X 1/2" solid steel spacer worked great. The screen fit like a glove. In my experience there was no need for anything thinner then about .0625 wall. However maybe it's YMMV depending on actual screen tolerances.

I can get a foot of that tubing for $1.70 from Online Metals here:

But, I'd much rather get a spacer from the local hardware store if it will work just as good without any sizing! I guess sizing it a bit wouldn't be a big deal though.

Interesting... I never had any luck with 1/16 wall pipe fitting the screens. I even tried hammering some on... sure would make it easier ... Maybe I should check some more screens...


Buy your screen first, then head to the HW store and try one!

I think I'll just order the tubing. I had a really nice MAPP torch but the thing overheats. I guess the orifice is stopped up and a new one costs almost as much as a cheaper MAPP torch... What brazing rod will work best with the MAPP? I read all the related posts but don't remember seeing this info?

 

[Lakeside53]

Pretty much any brass rod... it's all in the flux...

If you get a spacer make sure it's solid vs. seamed unless you want to braze the seam. The Ace H/W I shop at had both. In the solid they had 1" and 1-1/2" lengths. I bought one of each but found the 1" a tad too short. I used the 1-1/2" but cut it to 1-1/4" and stuck it in about 1/4" on the short end.

My brazing skills suck so I didn't want to be brazing the very end of the tube.

I'd try the spacer.. That tube will likely have $7 freight
Touch it with tapered reamer if it's reluctant to fit.

Yeah... I forgot about that! I have a really good hardware dealer that has almost anything in a fastener you could need! Anybody know anything about MAPP torches overheating on the tip of the tube?

 

[hawkfeather]

Anyone know how much a 361 muffler costs new?

 

[hawkfeather]

And I assume the fastener covers just pop off and pop back on??

Close to $70...

yes....

Happens all the time when I use my propane torches on Mapp:hmm3grin2orange:

 

[hawkfeather]

Well, I better not mess mine up when I do the mod then! LOL

I bought a used one, ebay $15, used it to mod and put the new
one up for safe keeping.

No screen though.

That looks almost factory...

Here's another option I stumbled onto:

Husqvarna used bolt on muffler outlets on 281's and they're available for <$20 w/screen. I have one on order for my 7900 but it might also fit 361 along with other saws.

You can also get a very cool looking BR600 outlet (Square tube), but... all these suffer from the problem of a low spark arrester area to outlet.. Prone to debis accumulation affecting performance. Also, I'd want to thicken up the metal behind the screws - the muffler metal is very thin.
