[@Achtelmann]

Nice german pronunciation =)

[@theroemergarage6119]

That "vacuum tube" being off is probably what caused it to bog. That is your impulse line for your carburetor and activates the fuel pump inside the carb. with it disconnected, means no fuel.

[@componentescarvalho4600]

I also think so.

[@fynbo1007]

Great job and you speak very good German Thank you for sharing your amazing video

[@DonnDIY]

German sounds cool and I just couldn't make myself cut this part out. :D

[@doublewide6]

Hope you get this message I tagged a video for you, I know it is a pain but you are going to make a video on Pet peeves and tag 2 other youtubers. Your video is under my channel search pet peeves. Nice meeting you. Bob

[@smittys19daytona]

Great tips! working on my second rebuild now the same 260 doing some other upgrades and mild porting it really makes a difference and a lot more fun to work with

[@leoramirez7583]

Awesome job I would only recommend that you give it break in running time.and also maybe add one more cap full of 2 cycle oil for at least the first tank. But all in all awesome job

[@bearbait2221]

If you push main seal in or out from original spot and get out of old seal grove it will seal for longer

[@aecrimnasirc]

Hello. Please tell me for me, why does my stihl ms 260 throw a lot of gasoline through the round screen in front, the top of the carburetor and drowns immediately after starting the chainsaw? New cylinder kit, new carburetor, new impulse hose. Can you help me please?

[@tobyallen2437]

Best video on this by far. It's amazing I live in Florida someone being worlds away I understood it perfectly

[@JuhaErkkila]

That was really nice! Thanks for showing through the "process" :) -Do you happen to know are the parts (cylinder&piston) some sort of chinese production or close to german? ;)

[@DonnDIY]

The last kit I had on was most probably Chinese. These parts looked like they had more quality to them but we'll see. I presume with sufficient oiling they will serve me well despite the origin. :P

[@lucagoller8947]

Ciao anch'io oggi pistone ..uguale ..260 bravo

[@mitchhayes1969]

Thanks for posting this. It gives me the confidence to do a total rebuild on my Stihl that shattered the piston this week. I’m going to watch this one while I’m taking mine apart.

[@DonnDIY]

I'm glad my chainsaw rebuild is of help to somebody. I hope it is clear enough to get the needed clues from the video. ;)

[@GuntersGarage]

Very informative video! I use the hot/cold method on bearings too, it amazes me every time how well it works lol.

[@DonnDIY]

Yup, although -5 Celsius takes a long time, deep freezer around -20 works way better. :D

[@Marass-]

IT was Not an Original Piston and Cylinder Kit? How long does it worked?

[@phillipkramer6638]

Good to do a leakdown and pressure test after running it for a tank of gas to make sure. Nice job which a shop would have charged you alot for.

[@phillipkramer1897]

Did you dirco the seals like the service manual tells you to?

[@carlcap14911]

This was a excellent teardown and reassembly like I have never seen before. Some things I didn't quite see clearly but, what I did see, was very informing thanks for a very good video.

[@DonnDIY]

No worries. Thanks for watching. I'm glad it was somewhat helpful. ;)

[@vasilegirigan5096]

💯👍👍🤝🤝💯💯

[@phel21]

There's a dummy sparkplug designed to block the piston that you use to lock the crankshaft when disassembling.

[@magicone9327]

Vaccum hose Is called impulse line. It allows the vacuum and pressure that alternates from the piston movement to activate the carb fuel pump

[@AYALARAMON100]

Nie video. buddy Muy buen video amigo

[@allthingsfishy3431]

Excellent video sir! How long (minus waiting for parts) does it take you to do a full rebuild?

[@allaroundtricks2546]

hey donn please make another video on your matttracks snowbike for suspension how u made your driveshaft and how you power it and brakes thanks!!!!! and what ccs it is

[@DonnDIY]

Here's a video that pretty much sums it all up: kzbin.info/www/bejne/gZvHnKhnfd2WpNE The bike was 150cc and had no brakes. ;)

[@mahdimaximieus434]

Good men. Algeria

[@Rafa-xl4uf]

I think that on the attached photo is shown the reason why this saw was damaged. zapodaj.net/388bb3341de7c.jpg.html

[@danhenderson783]

The seal will come out without splitting the cases. Just pry it out with a pick or small screwdriver.

[@lasurvivor47]

Excellent video....Thanks for sharing your time and effort!

[@usaisalwaysnumber1]

do those crank seals hold good and not leak in BACKWARDS

[@victor1990torre]

Chinese part

[@JapiTreFin]

Great video! I need to rebuilt one MS260, but I need to replace bearings too. Cylinder is scored badly between both transfer ports and propably pieces of bearing cages have done that damage. You've been using that Sagenspezi cylinder and piston now over a year, how it's been running? Any problems?

[@DonnDIY]

Although I'm not an everyday chain saw user I can't complain, it holds up well. No problems.

[@alexlawsan8758]

Cool rebuild man but you should think of sharpening your chain

[@tigxxl]

now when we have such greate toturial each one can bay ms260 :D NICE!!!

[@riv1950]

Very nice video, good description and good camera too.Thanks!

[@AmarNath-xm5vi]

Sir I learn also stihl Machine from you. From india kullu_manali in himachal

[@bespokefencing]

I learned the expensive way that the gudgeon pin circlp tang must sit vertically, and not horizontally Otherwise it will rattle itself out and destroy your new head and piston! 😭

[@DonnDIY]

😬

[@ЭрикАйрапетов-л2с]

Porsin german firma manel???

[@anthonymartinez8488]

Great video, like the funny moments. Good job

[@pawelaco]

Very good instruction, super saw

[@DonnDIY]

Cheers, I like that saw very much.

[@shaggydogg3786]

You are a good technician.. I’m overhauling a MS 361 now.. thanks for the video.

[@DonnDIY]

Good luck!

[@janhendrikfranke]

Pretty good german ptonounciation!

[@phillipkramer6638]

Did you use OEM top end or aftermarket instead?

[@shankarb2243]

[@kjellarvidsson630]

Real good movie. Many Greetings from Sweden. 👍

[@DonnDIY]

Cheers, greetings from Estonia. ;)

[@stihl3826]

Why would you not replace bearings with seal.

[@DonnDIY]

Two stroke engine crankshaft bearings suppose to be open so the fuel mixed with oil can also oil the bearings from the inside. I replaced the seals on the outside.

[@Bamse52]

My Stihl 261 broke down after only 3 years of cutting firewood. Stihl said it was my fault because I didnt use the Stihl oil and alcylat gasoline! 026 was a much more robust saw and I had one for allmost 20 years and used shell oil and 95 gas mixed 2%. Not happy with the Stihl 261 and Stihl support.

[@DonnDIY]

My grandfather has a newer STIHL. I worked on it and didn't like it. I try and keep this older MS260 as long as I can. I really like the ruggedness and simplicity of it. And it works great. I'm using motorcycle racing two stroke oil in my saw since rebuilt it in this video. We'll see how it holds up.

[@lukeoates6303]

Donn DIY regarding your comment about racing 2t oils. I have always used putoline or castrol R 2 stroke motocross oil in every small 2 stroke engine I run. If it's good enough for my bikes it's good enough for my saws. Plus they smell great too lol

[@ahmetakgun9240]

[@6771Randy]

You kicked the video into high speed at some of the most important part installation. How are we supposed to learn if we can't see?

[@DonnDIY]

Yeah, sorry about that, it goes together as it came apart, in reverse though. ;)

[@ЭрикАйрапетов-л2с]

Hae original germany firma manhel

[@MrTruper10]

Hello.You would be able to send the link, from where the new supply you ordered it, thanks. K.Dániel

[@DonnDIY]

From eBay. ;)

[@MrTruper10]

I saw it, but I do not serve a Teflon supply.

[@bobdudeface570]

Is there a steel bearing and seal replacement for the ms290?

[@MrSparkums]

Yep, look up "ms290 parts list pdf"

[@kylebjalme9006]

what kind of oil or lube did you put on the crankshaft before the seals?

[@DonnDIY]

Just some engine oil. Nothing particular.

[@superthom911]

Are you sponsord by philadelphia?

[@DonnDIY]

[@lobotomyy]

[@DonnDIY]

[@lobotomyy]

[@celsocarvalho4670]

Amigo adorei seus vídeos já virei seu fãs abraço

[@DonnDIY]

Cheers!

[@joeyrobledo]

You like cream cheese bro?

[@DonnDIY]

Of course!

[@danhenderson783]

It was sucking air because the impulse tube was disconnected

[@kiketurcios4416]

Good job

[@DonnDIY]

Cheers!

[@fendtonafarm8513]

so this is the big brother :)

[@DonnDIY]

Yup. I like the MS260 more than the 211, it has more power and has more simple carb on it.

[@traviswalker6831]

Good job!

[@DonnDIY]

Thanks man!

[@olebethge2261]

dein Deutsch ist wirklich gut xD

[@DonnDIY]

Dankeschön! :D

[@Sm-gy1jn]

Warum nicht auf deutsch?

[@sikoro5]

InstxcntExodus wahrscheinlich weil er Estländer ist und kein Deutsch Spricht ...

[@DonnDIY]

Ich habe Deutch gelernt aber habe niemand zu sprechen und habe meiste vergessen...

[@Sm-gy1jn]

Achso:)

[@benkanobe7500]

Can Stihl parts be ordered direct from Germany to USA as you just ordered that box of parts? It is very hard in USA to order Stihl parts anywhere except the Stihl Dealer which can be very expensive for DIY folks like me.

[@DonnDIY]

I ordered these parts on eBay

[@es5ape]

Man, I have the same chainsaw and I was looking for a set of parts. Unfortunately or fortunately :) in Poland there are a lot of offers from different producent with price starting from 25 euro till 100 euro. Can you please tell what was the producent of your new parts? I'm confused a little. Thanks a lot in advance!

[@DonnDIY]

I don't know the producer but the seller was saegenspezi on eBay and the product was: www.ebay.co.uk/itm/200784328632?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

[@es5ape]

Thanks a lot!

[@quevicular]

You put your bar on upside down, lmao

[@DonnDIY]

You understand that there is no up and down?

[@94SexyStang]

no he didn't........

[@MrSparkums]

Before full throttle it's best to run a couple tanks through on a new piston & head to seat the rings gently.

[@DonnDIY]

Yup, that's what the manual says too.

[@94SexyStang]

that's bullshit, if you want to seat the rings, nail the throttle. Break it in How you're going to use it.

[@bobdickweed]

Great video again...;-p

[@DonnDIY]

Cheers mate!
