Most people own an ms 170. And i hear them say its sucks. Well, after last years hurricane, i was helping peoole clean up. And nobody could understand how i was going so fast with the same saw. When we took a break i sharpened the chain. And to my amazment 4 MS170 owners were shocked that you can sharpen the chain. The ms170 is fantastic, especially when taking the price into consideration. I think the bigger issue is those who buy it aren't knowledgable.

Just bought myself a 2nd hand, 3 year old ms170, it’s not even arrived yet but already I know I’m going to give this a go! As well as side chain tensioner and felling dogs 🙌🏻🙏

Great saw had mine for 2 years and still killing it 👌🏼

170/171 is a great little saw, looks even better after that muffler mod!

Amazing the difference with a few quick mods. It’s still a small saw but seems to run quite nice

I use a 12 " bar & it's a great light saw. Use it all day without fatigue. Limbing & smallish tree felling. Keep it sharp & it's great. It gets more use than my big saws for a fraction of the price.

I didn't see this video until I did my own muffler mod on older MS180 and I figured out this way could be easy, efficient and kind of balanced for those smaller powerheads. I was also VERY impressed how the saw improved, also the sound was SO much better than before. I'll continue testing the modded saw tomorrow, maybe the frozen birch will show if there's any reliability left afterwards.

Thanks for the video. I've been wanting to switch to a rim sprocket but didn't want the loss of torque going from 7 tooth to 6 tooth. This simple mode compensates for that and maybe a bit more.

Well you convinced me I'm going to get one

Of all of my saws, up to a 461, I reach for my 170 90% of the time. Its so light. I run a 14-in woodland pro bar with 3/8 .050 full chisel chain

Got one awesome little saw

Good machine

I've had mine about 4 years... Long story, but I needed a new chain saw, $180? Man, I was skeptical, how good could this be for $180? I'll tell you, the more I use it, the more I like it. I thought it was going to disappoint, boy was I ever wrong. Lightweight, easy to use, quick and very nimble and just downright fun to use! No issues with mine, running that premix 50:1 Echo Red Armor fuel in the can. Ethanol in our gas here, lost a few 2 cycle motors to that crap, and said never again, and went to this stuff. All my equipment now starts when I need it to, no more fouled plugs or carbs, love this fuel. I'm a homeowner, mainly use this little saw to clear limbs and what not in my jungle in the back yard, use it maybe a dozen times a year, if that... Now, I have a few trees down and what a mess... Just ordered the heavier Oregaon 16" bar and the .050 chain, along with the Stihl tensioner like on the 180 with the spike kit... Will do that muffler mod too, thanks for the video!

Been using this saw for about 4months and I am in love with it! I don't have a lot of chainsaw knowledge but i want to increase the power of this saw. heard about the 215 wt carbs but i never worked with carbs and don't know how to tune them properly. I did the muffler mod which was a crazy upgrade. Atm still using the stock 16in bar with the 3/8 picco .43gauge chain. But i am looking for an upgrade for the bar for cutting power but i got no idea. i heard .50 with 14in the bar but idk which bar. From your experience what is the best bar/chain can i get for this ms 170 beast?

How light did you say this saw is? I might grab one when they go on sale... Something to tinker with....

Man I like your video and I'm heading out to the shed to do the muffler mod on mine. Question: at idle and under normal operating temp or at cold start what causes a slight rpm dive when I hit the throttle? It regains composure quickly and runs full rpm, no performance issues other than that dip when I throttle up from idle.

Great mod, very interesting, Ive a dumb question. So what did the change you make actually do ? Just increase airflow and increase power and speed. So why wouldnt Stihl do this in the first place and have a more open vent? Are there disadvantages to what you did ?

3 upgrades i did new bigger carb and xd series bar and carbide type pd3 brings rm up to 11 k max, still cuts 10x faster 6sec for 14 inch thick 16inch bar

When I watched the video the Likes were 170. And now it's 171.

I have a 250 Stihl chainsaw I don't think it has much power what should I do

Thanks Bro it got much better

I don't need more power, but after two years of light use, my MS170 bogs down and won't make power. It starts fine and revs okay with no load, but when I try to cut something it bogs down and quits running. I removed the screen, but that didn't improve matters, so I'm going to try your muffler mod. Thx!

♦Put a wT-215 carb on it. Need to adjust the choke linkage to work (easy bend at the bottom 90° angle).

I got the MS180, i open it up a bit but ill still leave the spark shield on.

Want to see this after it gets some run time on it too.....

Original size bar ?

I have same Ms170 Stahl so yes would like to see a whole tree down,

Where is the primer bulb or does it have one?😕

The timing advance mod gives you more power than the muffler mod. Both mods together turn the MS 170 into a little beast. Advance the flywheel 1/4" and your golden

Would this mod make the saw louder?

I have one and so do a few of my buddies. My only complaint is the air filtration system, what an absolute joke.

Hard to find a sale anymore

The muffler makes faster cutt?

【from HIPA】Would you like to test my accessories for your equipment?thanks

No spark arrestor will get you fined.on USFS land.

Where is your screen very important

Safety is not a priority.

ms170 is a fabulous saw. why do Americans make fun of anything less than a v8?
