Bought another saw, the MS 361. I've read on the forum about muffler mods and such about other models, but would this be one that a person would modify? If so, why? If not, why?
 
who, the most common mod on the 361 is the muffler mod--you can find tons of info on it at Arboristsite.com (I think you've already posted that on another link). Some people have tweaked the engine, but the muffler mod is supposed to have a big effect. You can also buy one modded by someone named Wojo on eBay for $125 shipped; I've heard much criticism about the guy, though.

I like wojo makes stuff out of ss how old is this 361?
 
I have done a few upgrades to mine. Put the 3/4 wrap handle on it: like to be able to cut both front and back of tree without having to sometimes work around stone walls, etc., also it works well running up a tree limbing it out. Upgraded the oiler, just figured for the bucks, I'll take a bit more oil on the bar and when buried in a fair size oak, it was lacking some. Lastly, I had the muffler modded. I can't leave stuff alone, but haven't been unhappy with any of these mods. Now it is a very good mid sized tree saw.

What sort of "upgrade" did you do to your oil pump? I had to replace my pump about a month ago after a bearing failure allowed the clutch hub to grind a hole right through the oil passageway of the pump. I put a used (ebay) pump in the saw and its now consuming about 3/4 a tank of oil per tank of gas with the pump turned all the way up. So if mine oiled a little more, up to 33% more actually, it wouldn't hurt a thing. What pump"upgrade" have you found for the 361?
 
Install either the internals from or the pump from a 460R saw. Will put out lots more oil than the standard ones. If you look up 361 oiler upgrade, you'll find the Stihl part numbers.

Edit:
Found the part numbers for you:
1128 647 0602 oil pump piston
1128 647 4803 oil pump control bolt

or

1128 640 3250 oil pump assembly

Best thing to do when you hear people saying bad things about someone is to find out for your self. Yeah, there are a few people bad mouthing me and what I build. If you do a little investigation on your own, you will see hundreds of satisfied buyers on eBay, and not one negative feedback after over 600 transactions.

Yes, a 361 can be modified with amazing performance gains. And If you need an entire muffler the price on eBay is $125. But, if you can send your muffler, $75.00.

I challenge you to try to build one with the same quality materials, and with the same quality workmanship at the same price. And that's 316 stainless steel pipe, Nickel alloy heat treated screen, Welded with stainless wire and the proper welding procedure (you figure that one out). Also, with a brand new Stihl 361 OEM muffler to start with. And then paint it with $277.00 / Gallon High temp ceramic coating. Then add in a little for postage (which I never charge for).

And guys, I split and burn my own wood.

Thanks,
Scott.
 
I have one and the only one I have ever seen with SS...sure theres more but I havent seen any. 4 years old!

a few there jags but that 460 was loud and proud before any work was done but always cutting big stuff the thing was ported and muff modd. almost out of the box. My 361 runs a small bar and the extra emmth not needed there..but if I had to run a 25-28 in. on it there would be a few modd.s to it aswell.
 
Scott,
Thanks for the clarification. I think the criticism is over the cost--from what I've seen, most people charge around $45 for the mod. Who knows, maybe I'll be picking one up from you. Though the $125 puts it just a little higher than I'm willing right now. It's like a generator: at $500, I'd own one but at $750, I'll hold out for the lights to come back on!

Let me know the outcome of the 455 Rancher muffler if you decide to have it done. Keep me updated please
 
The work scott does is outstanding and SS no one else I have seen uses it. makes me want to do the 361....
 
Scott, do I get the shipping info. off the E-bay site? What's your turn-around time? I'd need it back by mid April. Thanks, JB
 
Thanks will keep an eye out for it, If you want you can PM me. If successful may have mine done too. But gotta finish up the load of logs first. The 455 is the only saw i have right noe to handle the job. Keeping an eye on CL for a dealand told my local dealer if he gets any trades in to let me know.
