I did the 40:1 fuel MIX to my STRUMM 52c and the pisto/rings as well as the top cylinder was damaged

Who would dump engine oil derectly into the fuel tank then add gas ? Not a good idea.

artificial intelligence voice is annoying .

Computer generated narration, and out of date info? Thumbs down from me.

32:1 on everything.

Dumb video

You really should be mixing more oil into you fuel. More oil will give your saw more power, obviously don't over do it. Between 40:1 and 32:1 is best. And never use pre-mix fuels!

I have both, I think the 250 is a better saw, seems to be better built, and it has 2 bar nuts.

I bought one new in '23 and have been very satisfied with the performance. I have other saws that I use for limbing and regular cutting. The 391 is used when cutting large maple, oak or Tamarac pine. The power of this saw is tremendous and I wouldn't need anything bigger for my use. I'm 71 years old and keep up physical stamina by using my saws 2-3 times per week. This saw is my ideal machine. Thanks for your info about air filter replacement- I'm buying one tomorrow!

261 also has a winter shutter. I love my 261c with a 20" bar. Well balanced comfortable saw.

just memorize 40:1 is 3.2 oz. of 2-stroke oil to 1 gallon gas … 50:1 is 2.6 oz. of 2-stroke oil to 1 gallon gas … best to use gas WITHOUT ethanol and use 95 octane gas (available at Shell Oil gas stations)

Serial number for Stihl chainsaw My MS461 was made in Germany, my MS180 and MS310 was USA. • If the first digit in the serial number is a 1 then it was manufactured in Germany • If it’s a 2 or a 5 it was manufactured in the United States • A 3 means it’s manufactured in Brazil • Serial starting with 8 is Chinese made • Starting with 4 means made in Austria

251/271/291 all suck compared to the 250/270/290.

Pretty shit video. Specs are fine and true but the recommendations for which one to get are misleading and not helpful...

Not right, 391’s have Deco

I bought the MS462 and it performs flawlessly

This video is very confusing, or just plain wrong to the extent that it should be removed and corrected. The MS391 has a decompression valve, the MS362 does not. Both models SHOULD come with a 25" bar (and chain). The MS362C (NOTE THE "C") comes with the automatic carburetor adjustment for optimal rpms, the MS391 does not have this. The MS362 turns about 1000 rpm faster than the MS391. The MS362 comes with a better air filter than the air filter on the MS391. The MS391 has a plastic body, the MS362 comes with a metal body. The MS362 has retaining nuts on the chain adjustment cover so they don't get lost in the woods, the MS391 does not have this. Each model has a different sprocket - the MS362 has a better sprocket and bearing. The MS362 has ¼ turn screws on the air filter cover, the MS391 has threaded screws (more difficult and time consuming to remove air filter cover. The MS362 is lighter than the MS391 and a Caterpillar D11. The MS362 has a felling line, the MS391 not. Both chainsaws are very good and the MS391 will work fine on the farm and at the house. The features on the MS362C are meant to increase output/productivity and reduce downtime. Carb-yer-ator? 🤣 Earth first, we can log the other planets later.

Nice AI voice😂😅

Thanks 💪👍👍👍

I know nothing about the 362 but think ill stick with my 391. Yes its heavy but cutting 40 inch red oak it handles like a dream. A sharp chain and let the saw do the work.

Around 6:30 it says when the engine gets to much fuel and not enough air it causes a lean condition. Its wrong its a RICH condition, not lean. A lean condition is to much AIR!

The 261 sounds like it has too many bells and whistles. Just more things to break. Ill get a 271 or 291

Carbulator😂

A I sucks. Can't people talk anymore? CORRECTLY!

Stopped watching with the computer voice. Cant trust that shite

Ok video but the computer generated voice ruined it.

this video is DUMB and longer than needed. It just keeps repeating the same things over and over

No chainsaw has a zero emissions rating. Even an electric saw, will be flinging oil particles off the bar. Interesting that the 261 in the US/Canada, the power output appears to be 2.8kW, whereas in Europe it’s a 3kW saw. The the older 260 used to be 2.8kW.

Ill keep my 250 any day. Probably ten years old . A couple of carbs through the years and still going strong. No disrespect to the 251 but when the saw runs out of gas you are ready for a rest anyway when cutting firewood continuously.

Why computer voice? Immediate no

391 is going to have more power due to larger displacement….nope.

Shamefully bad video

shit video with some stupid ai talking

Computer talking equals generic video which also equals don't watch

What about the color of the mixed fuel? If had mixed fuels around my place and not known the ratio. Blueish, greenish and in between.

Getting ethanol free gasoline is a challenge for me. Hbu?

What about 45.1 fuel 🤔

SUBSCRIBED!

useless

Good comparison video, however, the easy start feature is not featured.

251 is best,no problem whatsoever in any area! I've got the easy start model!

First time viewing your channel this is a lie the MS 250 burn gas very very good i have One and i have no problem with fuel it's good and fuel so that's not true in what you said about fuel efficient

Uk 50-1 is 20ml to 1ltr 40-1 is 25ml to 1ltr 32-1 is 30ml to 1ltr 25-1 is 40ml to 1ltr

Im so tired of Ai voices on every damn video i watch. Just butchering language one video at a time.

I ran every chainsaw there is and I think the 500. I is the best hands-down.👍

I. CANNOT. WATCH. THIS. AI. GENERATED. SHITSHOW. I’D. RATHER. LISTEN. TO. KUMELA. HARRIS. SCREECHING. ABOUT. WHATEVER. TINY. COMMUNIST. THOUGHTS. ARE. BOUNCING. AROUND. HER. EMPTY. SKULL. Is that hard to read? Yeah, well that what listening to this video is like.

I like 30:1 with high flow intake and exhaust.

They used to use 16 to 1 mix in 1960s 2 stroke because they had brass parts that were fragile.

👍

What size is the retaining nuts holden the carburetor to engine
