Some shops try to steal your saws so watch out for them folks She is a very smart mechanic and knows her saws she will never be slow and always busy 😊❤

Good job with your diagnosis of non running 026. This gives me incentive to attempt to repair my old 026

I bought mine new 32 years ago and it still runs like a champ and I use it 3 or 4 times a week on my property and carry it on my ATV to clear trails. Replaced the carb once and of course the chain over the years plus good maintenance goes a long way too It is a great saw to me and served me well.

Thanks for the inspection. I have been keeping the air filter as clean as possible on my 026 but I didn't realize that it could be split for further cleaning. Good to know!

Really enjoy watching you start from scratch and work through all the possible / probable causes of the problem. I appreciate the way you tell us what and why you are doing things without relying on click bait along the way. 😊😊

Another great video. Very detailed very professional

Thanks for sharing Erica. I am very impressed with your thorough, calm, and methodically efficient diagnosis. Best of good health, prosperity, and long life to you and yours.👍

I lovely 026's. I got one of the last 260's. It ran like a dog. New 250's out ran it until I opened up the muffler like 3+ times the original size. I also run it with the air cover off and adjust carb accordingly. I run it hard! Its fun!

i only have my laptop speakers , so your whole lesson was whisperjng cheers , again

I would have checked the compression. I had a ms260 come in the other day that had a scored piston and cylinder similar to your 026. I checked the compression it showed 140 psi. Ran it for about 10 minutes and rechecked the compression with it warm, the compression dropped 10 Psi. I pressure vacuum tested it and it passed. The owner is going to keep running it until it won't run anymore. Only time will tell.😅 Awesome video hope you keep making chainsaw videos.

Very informative, thanks for sharing. Barrie, Ontario.

Awesome video, thank you ,the screw on the carb might have come loose from vibration

Excellent job, looks like it had been straight gassed and the customer wanted you to confirm that! She probably loaned it to somebody and it come back in that shape!

Awesome video I too have two of those workhorses and starting a project on the third one

I much enjoy your videos and methodical way of working through problems. I was surprised an 026 still had good seals!

A top end rebuild with OEM parts is expensive. Especially when u have to pay a saw shop to do the work. Aftermarket top end kits are available and inexpensive if the saw owner has the ability to rebuild it themselves. It’s surprisingly not that difficult. I’m currently rebuilding an MS 361 that’s 18yrs old that belonged to my dad.

"Not worth fixing but we'll keep it" We will do____________________________with it" Insert your guess in the comments lol!

nice science experiment on an old 'junk' saw when it came in the door. What you found is an example of why shops say they will work on this type of saw but they really don't want to spend any time on it because they know the parts to replace it will often be more parts/labor cost than to buy new saw. Last shop probably had their summer intern Mechanical Engineer work on the saw

Good job keep up the good work 👍

My name is Ian grant first time watching your channel.Just want to say I repair chainsaw and I just want to say that they are very good.Aftermath to chainsaw Parts out there not all of them.Is good. I use Some of them and I never have no problem. I alias, tell my customers do use little more to strokes. Oil when mixing the fuel Why I'm saying this is because I use chainsaw.I Cut down trees also on the same thing I do. Makes my fuel a little bit Richer and I never had a problem

Yeah cylinders clean up easily and we can use a meteor piston. I just did that ti my 026 and it runs like new again! I got the piston kit and base gasket for 30 bucks. Cheap to have a great running saw again!

Excellent video, getting ready to put a new top end on my 024 as old stihls are better

Mystery solved. A leak in the carburator due to screw not being on tight. Nice analysis.

New subscriber from here is SW France. nice in-depth video - thanks for uploading

i had exact same issue with my 026, tough lil saw though...thumbs up !!

Id love to get my hands on that saw and rebuild it

great job

Great video!

Great video, you're good with saws. It's nice to see! I have 2 026s, I love those saws. Maybe I should go do what you just did so I can keep them alive! 👍

Can you explain the purpose of the impulse hose and how it works in one of your videos sometime?

Very cool 😎

Enjoyed your video😊

Great video and knowledge you have. I use one of those magnetic metal dishes for screws, etc as I always used to end up looking for bits on the floor. Best wishes from across the pond 😊

Hello, great video. I just discovered your channel. I have the same exact saw which was given to by a friend. He got it at an auction for $2. It was completely torn apart, cylinder off rings stuck with bad scoring. Didn’t give it much hope but went through it, did a quick hone and got the piston cleaned up and I’ve been using it for the last 15 years, crazy.” Your results may vary” haha. I have two other 40 year old Stihls and use them often. Keep up the good work.

In the UK they were called Wood Boss, mine is 1886 that we bought in 1992. It does not get a lot of use, 5 years ago it needed some new plastic pipes for either the fuel or chain lube ?I can't remember which but other than one new chain it has been 100% reliable and enough power to take on heavy work Oak trees - genuine parts were still available a few years ago and may be today. Its starts reliably every 3 years and never needs the carburetor adjusting. It has an 18" bar and cuts anything I need it to with ease. Compared to a modern saw it probably uses a lot more fuel but I'm not a daily user. The plastic is all intact and faded but the saw will outlast me

You are so good

Interesting my dear

Like her much better than chickanic

Scored piston could easily been from a lean mix or no mix at all for even a minute of run time!

I'm behind in my video watching!

Ez rebuild on the 260.

This is why i dont loan out none of my small engine equipment

Great job of diagnostic work would have liked to see a little more close up of the throttle disassembly but you were very good with explanation Thanks and God bless

Where can I find those tools you used to repair the chainsaw?

That is really good diagnostics! I was thinking the same thing when I saw the bubbles out of the carburetor, but also thought I didn’t see vacuum building when the engine was tested and thought crank seals. Had to look again when you said it was holding vacuum. Where did you find the plates to adapt and seal off engine ports? I could use some of those as well!

I use the MS660 on the.Ms250

I read a story about a fellow that ran a chainsaw shop in Washington state and his Dad before him. They said that before the 1970's a scored piston or cylinder was almost unheard of, only if someone mix the fuel wrong or not mixed at all. THEN all of a sudden they started getting countless saws only a few years old all scored and no compression. Do you know what happened in the late 60's?? They went from 16:1 or 24:1 mixture to 50:1. I restore outboards and restore 1940 and 50's motors with NO scoring either....16:1. Until the late 60's there was NO such thing as mixing oil or 2 stroke oil ....you used 30 weight regular motor oil. THAT is what the manuals called for. Also modern saws revv TWICE as high as old saws yet they say to use 1/3 the oil...WHY? To make sure your saw lasts a few years ONLY. Mix your saws 32:1 or NO LESS THAN 40:1 and your scoring problem will fix itself.

please update and say what customer decided to do.......

😇😘merci et a bientot

My money is on she lent it out and they straight gassed it. Good detective work!

Like your approach, I'll have a 251C and run it on 40/1 for better lubrication, unlike 50/1 Sthil recommends! What's your opinion on that and also should i adjust the carburettor for that since it runs a little more rich??? Worth mentioning, I only ru the saw for firewood when I go camping for cooking and stay warm at night 😊!

Ah , neat disection... Taking a chainsaw Stihl says isn't worth fixing, but still wanting to know what specifically went wrong.

Does not look like the original carb?

I'm surprised the engine held vacuum with a scored piston and one stuck ring. I really wanted you to put fuel in and try to start it after solving the carb leak and the cylinder holding. Not expecting a miracle but I wonder if it would it run?

I would fix it. Put new cylinder, piston and both seals and boot.

Do you have a bore scope for looking into not only cylinder thru plug hole but thru intake and exhaust then capture the vid and or pics?

Not worth fixing but we'll keep it ,yeah right 😮

Put an aftermarket top end. Not as good as stihl but way cheaper.

Must have been TDs shop

where is the engine/serial number located ?

When testing the vent would it be wise to pinch off the vent tube to insure the tank and cap are not contributing to a leak down?

Many scored saws run

varied reviews on this saw, mostly trending to a good saw..what do Tyler and you think of this saw? btw..great job with saw,,must have taught Tyler everything he knows..:)

Now I’m just curious and I wanna ask: What would happen if the saw was run with pure gas? (That has to be a very common mistake, right? Forgetting to use mixed fuel…) I would think the lack of oil in the gas would make the engine overheat…and score the cylinder real bad due to the piston expanding…then possibly someone tried to fix it and loosened that carburetor and just put it back together real quick when realized the damage…so the leaking carb would not be the primary cause but just the result of troubleshooting…because in my opinion, a carb leak on the pump side would piss gas everywhere (as opposed to leaking on the other side would suck air, therefore running lean and burning it up (scoring cylinder and piston) Am I right?

Somebody forgot to put the oil in the mix and seized it 😢

Saya pernah punya stihl 056 mesin itu sangat kuat. Sayangnya parts nya susah sekali di sini.

a microphone would be handy , cheers

I meant air filter not fuel filter on how do you clean the air filter show in video please

I would have just got a good aftermarket top end kit for it and rebuilt it.

Anybody know how I can find out what she's saying? Does she get it fixed?

Block is scored

I would throw a Chineesium motor in it and carry on.

How much would that saw be new....700.00? You can buy a GOOD QUALITY cylinder kit for 100.00 or a cheap one for 50.00 and a couple of hours will put it in. I don't think a new one is in HER interest.

Probably ran lean because of the air leak or got some straight gas, piston and cylinder shouldn't be too pricey, as long as the crank and rod bearings are okay. Just started watching you but you seem to be a better mechanic than that other chick.

That was a boat anchor disguised as a saw. Not even the plastics are worth saving. Buy a new saw.
