[@TarylFixesAll]

Your friend knew If he loaned that saw to any one other than you and if it broke he would be out of a saw. LOL. Nice fix.

[@bruceb3786]

@Rob Bryant , some "friends" are CS, like that little white spot on top.

[@markatkinson9963]

@Rob Bryant why I don't let anyone barrow my saws.

[@user-xy2gc7pl1b]

Very nice job I'm doing my first full rebuild teaching myself with the help of your videos very helpful be good to you and yours brother

[@doggie946]

Enjoyed the video...looked challenging at spots but you never shared any frustration...just stayed positive and pushed forward until the job was complete. Thumbs up.

[@luvthesnow]

Nice job. Got it going. I had the Stihl manual to follow and it was still tricky. I've done a few since and it goes better each time.

[@WhoDaBoss-dc4or]

I bought my ms250 for $300. Your offer was very generous. Fortunately you have the ability to rebuild it for him. Being that the saw is well used , I think that's more than fair. If it was my saw and you were my friend , I'd probably pay for the parts if you'd do the labor. I'd get back a good as new saw for dirt cheap and you'd only be out time for breaking a tired chainsaw. Good video as always 👍

[@SA-FormerlyCreamy]

Nice job! I’m doing the exactly same rebuild right now.

[@charlesgraham843]

I wouldn't have had the patience for that job.

[@williamcarboni2614]

Well done DW, getting that linkage apart was like a Chinese puzzle. Learned a lot about chainsaws. Thanks stay safe and enjoy the ride.

[@TheKrayusKorianis]

It's actually simple. Set the lever to run, manually close the choke butterfly, pull choke linkage out from the left side.

[@shadybrook11]

I did a similar job with my Stihl (seals), but first I had to watch several videos (mostly Donyboy73) over and over, and I went really slow. Now that I know all the tricks, it was great watching how you intuitively found your way through. Impressive! p.s. flushed with success, I disassembled my Stihl KM55 trimmer, but got totally lost in terms of reassembly!

[@joeo1352]

Came out great 👍

[@iangrant4466]

This MS 250 chainsaw is one of the best Stihl chainsaw ever made by Stihl easy to work on and easy to use when cutting tree powerful and fast

[@aaronbates500]

100% agree.

[@woodlanegardenequipmentrep9149]

...that, and the 023c..l just rebuilt a ms250 for a customer...l had to watch this first, though..

[@AndreasBrOlesen]

It might be a good saw, but it is definitely not easy to work on. On my husqvarna saws everything is much much more accessible for doing maintenance and cleaning. It is a pain to remove the plastics from the MS 250

[@steveyork8069]

I tear mine down this far several times a year just to clean it really good,just did my ms250 today doing my 461 tomorrow.Did my 661 couple weeks ago I hate letting my saws stay all mucked up.

[@damonburroughs5283]

That's what a pressure washer is for and some plastic clean

[@Willies_shop]

I have done this to two of these saws and If take an extra few minutes to remove the clutch and flywheel the entire block will come out from the plastic housing and it will be much easier replace the cylinder. The seals can be replaced at the same time. They should be replaced as they can contribute to a lean running engine.

[@TheDp1965]

Thanks for the video. Have a ms251 I need to do this too. Cheers

[@robertrhodes9123]

I have a homelite I bought in 1984 that I have had very good luck with. I use it a several times a year & (knock on wood) have never had any problems. One new bar & couple of chains is all I bought !!

[@crisprtalk6963]

[@thematta2274]

Very well done on not an east job.

[@johnclarke6647]

Just wait until you try to install that right front grommet back in the rear handle. That sucker is just like the 029/290, a pita. I found it easier to re-attach the rear handle right front grommet, first, then rotate the rear handle, downward, and then pull the boot through. It usually tries my patience and I have done it lots of times. I pull intake boots into the rear handle with a piece of string. Once you get the boot in and the kill wires through, just screw the rear handle back to the cases and the rest is pretty easy.

[@kennethtephabock5634]

Great video doublewide6

[@michaelchilders6056]

Looks and sounds like you did a good job! Curious what the compression was once finished? Thanks for what you do.👍🇺🇸

[@dave1135]

I just had a 025 in, an older version of the 250, it needed a new intake boot and pulse line and fuel line and carb. Was a pain to put in. Had to completely dismantle it. But customer wanted it done. Ran really well after, pretty good for a 25 year + saw

[@TheKrayusKorianis]

My cousin owns an almost 30 year old Stihl 025 saw. He just had to change the fuel line last summer.

[@ChuckNorris01]

Thanks I needed this

[@watermanone7567]

Really good job. The new Husqvarna saws are way better than the Stihl's and easier to work on. I have stopped working on the Stihl's in my shop unless it is for a friend. Thanks for a great video.

[@stevieg.4816]

I don't like fast forward as we miss some very important details, but I like your video it will help a lot thanks.

[@jbbolts]

what size bar were you running before and after the fix? is it still working?

[@larryreno8293]

You should switch to a different sealer. You put two different sealants on the same joint. Those sealers are different composition that dry differently and adhere to surfaces differently. Motor Seal by permatex is made for direct contact with fuel and is a adhesive sealer.

[@ryanray5533]

I was suprised that he didn't have an air leak!!

[@johnclarke6647]

A little oil on the rings and grooves really helps.

[@tommccarrick18]

Hi - would you know where I can get a carburettor kit and a piston & ring for a Husqvarna 300?

[@johnclarke6647]

I always put the intake side circlip on, first, to make sure it is seated correctly. If the intake side circlip comes out it will trash the cylinder and piston. If the exhaust come out it will end up in the muffler. I use Playtex Moto Seal on clamshells and TB 1184 or Dirko on pro saws.

[@animalcorvair]

just got done getting one running...would not start, had spark. new fuel ,,not even with carb cleaner.....well the muffler was full of bad gas,,, took it of started right up//dried out the muffer ,,running great now

[@nashguy207]

I have a MS250 they are a descent saw. You are a better man than I am I will not work on chainsaws they are pain to me. I will work on my trimmers and blowers but not my chainsaws. LOL Good Job Buddy. Stay Safe. Stay Healthy!

[@beingsneaky]

Did you go for a stoke size piston or a big bore one?

[@dwpetty3723]

They sure don't make those easy to work on, great video

[@jeremyanthony9300]

Bob, would that short block fit a Stihl ms211 ? Let me know cuz i am think of buying that exact cylinder for a ms211 .

[@Jeremy_810]

I ran my 250 out of gas also. It ran through about a half tank after that before it died and wouldn't restart. The next day it was fine though. I did it again months later and same thing, it died halfway through the next tank and wouldn't restart until the following day. Saw seems fine but I definitely gotta be more careful.

[@keithsage1593]

Our saw has been rebuilt 3 times and I am still using it.

[@1stfloorguy59]

Damn you have to take so much apart to get the top end off :(

[@butler386]

Hmmm, I don't find it difficult to work on chainsaws at all. I pick them up and take them to my neighbor or to the curb. Problem solved. I would never been able to get it apart without breaking stuff or not remembering how to put it back together again. You certainly have a talent for fixing things. Thanks for sharing and stay safe.

[@hunter1953]

If I ever see a chainsaw like that on the curb I will drive right by and smile at the person that picks it up

[@TheKrayusKorianis]

They're actually very nice saws and easier to work on than a Husqvarna which needs the handle removed to even get the carb off.

[@brandonlara1186]

How did you remove the crankshaft and pistons can’t seem to find any video what so ever

[@mikespain8655]

Most 2-stroke equipment failures are from air leaks. Obviously, more air, less fuel leans it out, and scores piston, rings, cylinder. First, pull muffler and look at the dang piston. Do a compression test. Do a leak down test with a Mighty Vac. What about the impulse line, crank seals, fuel lines, etc.? I've used Meteor (Italian) pistons, rings, cylinders, etc. with good results. Go online and read about them. OEM Still parts for rebuilds are often cost prohibited. Farm tech makes some cheap stuff. You said $40 bucks for MS250 top end rebuild kit. Man that us cheap! Scary cheap. Chainsaws are very finicky to work on, and to keep running right. Highest weight to power ratio of any piece of outdoor power equipment. Never force stuff when removing and installing parts. It all fits, just gotta be patient and persistent. Oil everything up nice on rebuild with 2-stroke oil as you go. Use compressed air ONLY to clean a chainsaw, and carb cleaner. Run it after the rebuild just like you normally do. Some people like to baby it, and some don't. Run 50:1 good synthetic Stihl premix. That means right after you rebuild it. Not richer because it is dress top end. If no air leaks are present, no problems. This saw failed because it was going to fail. Why? Don't know because never got definitive leak down test, or look at piston and jug. 4 cords of wood per year is not much. Never run a saw without the bar on, and drop start it like a man. Merry Christmas! Enjoy your channel.

[@fendtclaas8689]

Hey Bud I've ran a saw out of fuel a thousand times. No damage.

[@stevethomas7463]

👍

[@rverro8478]

3 or 4 cords is a lot ? Try 10 to 15 cords/year AND, clean the damn thing after EVERY use. Saw dust may have clogged the cooling fins thus, overheating. I'm no small engine mechanic BUT, comon sense prevail.

[@johnclarke6647]

Pegs are called anti-rotation pins.

[@rickvb2709]

Dang, that was bad luck, good fix though.

[@pugcommander7561]

I think it's funny you used a "C" clamp for your letter D.

[@crisprtalk6963]

Its called the MS 250 because it takes 250 pulls to start it.

[@patthesoundguy]

Any more than 5 pulls it's broke... A Stihl should start in 4 pulls or less. I can leave mine for a year and it will start in a few pulls

[@TheKrayusKorianis]

@@patthesoundguy Exactly. Why did he pull so much? Because he flooded the engine with fuel. Set to choke, pull until it offers. Set to high idle, pull until saw starts and chain spins. Blip the throttle to set the saw into run/idle.

[@Jeremy_810]

4 pulls max on full choke even if it doesn't seem ready to start. It'll still start with a few pulls at high idle. It only took me one time having to start this thing after I flooded it to learn my lesson.

[@do-it-right5169]

Bruce Pender mentioned u the other day in a video. Brucepender

[@glenhale8234]

You did a great job on the video. I'm sure I could fix my Stihl fs 110 weed trimmer that now has two broken bolts in the exhaust bold holes. But, he thing that seems impossible is finding the Aftermarket Cylinder Kits. The part number for the fs 110 is: 4180 020 1205. I can't find it on eBay, or Amazon and Stihl doesn't seem part directly to consumers. So how in the heck do you find parts for the Stihl!!

[@cnw-jd9tt]

I’m buying one that’s 2 years old for 200 that works etc

[@chet3larson]

Nice work. Gosh, I hate those saws. 025 or the 250, same miserable saw to work on

[@beingsneaky]

yeah thats alot of work. now imaging paying a shop 100 bucks an hour to work on it.. lol plus parts and they wiuld ahve went oem so very expensive..

[@cameronsienkiewicz6364]

Pretty sure it’s a “chainsaw”, not a “chainsaul” lol😝

[@ohiofarmer5918]

Appreciated the warning about not running it out of gas because it means out the fuel mix. Did not realize that. Exceeding the oil to gas ratio does the same thing, believe it or not

[@John_D2]

Negative. You end up with fuel that's not being burned if it's not tuned right and loss of power. Running one 40:1 or 32:1 will not burn it up , even if it's tuned for 50:1.

[@TheKrayusKorianis]

Running a saw out of gas does NOT mean it is out of oil. Oil separates below the piston, lubricating everything. Residual oil is sent to the top of the cylinder by the transfer ports with the fuel. That's why 2 cycles smoke a bit when run, they burn oil.

[@vincentshelpfulhints4085]

I have a feeling they design these saws so that an everyday person will not work on them and pay a Stilhl dealership for the repairs or purchase a new one,, my opinion

[@jeremyanthony9300]

I did a rebuild on a husqvarrna 350 one time. It was a p.i.t.a.

[@crisprtalk6963]

I find it difficult to work on chain saws. I'd rather change out the timing belt of my car.

[@garny3766]

My thoughts... 1) these are consumer grade junk saws. HF Chinese saws are about same quality. 2) Clone cyl. kits are close to same specs. What I’ve found with these is the port timing and/or volume are not quite the same. They will run but never seem to have the same throttle response and they have cheap ring material. But for the price they are the best option and what I tell customers is this should now become your back up saw. 3) case halves. For the life of me I don’t know how you don’t get leaks using that schlack and silicone together!! I bought some of that one minute stuff after watching you and I gotta say that stuff is shit. I used it one time. I went back to ultra black. My two options for sealing case halves are permatex ultra black and yamabond. This stuff along with a can of brake clean is all you need. 4) curious to see ring gap on oem cylinder. 5) bottom case half. Check case flange and steel thimbles. What I’ve found is the case can deform @ thimble and this will not allow the 2 halves to join and seal correctly. 6) best saws are the ones with cylinder and crankcase separate. Called proline saws today or every saw that was built 30-40 years ago.

Chłopie za takie rozbieranie to tylko łapy obić, nic się nie znasz

[@portagepete1]

Too many commercials, You can't use cheap oil in these saws or you will be changing the piston every time you use it. STIHL recommends using double the oil if you use off brand oil like 24 to 1 but that is not good enough if you go off brand use Caster oil synthetic that might be what Stihl oil is anyway. NEVER use junk oil like Briggs & Stratton that burned my saw up even with 20 to 1 mix.
