"You're basically fishing around in the dark, trying not to put your tool in the wrong hole." It was an accident. I swear it was.
I am a 20+ year STIHL Master Whench Service Tech in the Northeast U.S. The MS250 is an amazing chainsaw, the power to weight ratio is amazing. HOWEVER they have more pull resistance than any other saw in the line up. It will start in the same amount of pulls as any BUT you have to pull it like you are mad at it. I had a meeting with all of our counter guys and made sure that they pass that info onto the unsuspecting customer who is purchasing the saw. We have had hundreds of these come back for hard starting, meanwhile there is literally nothing wrong with them per se other than the customers not pulling hard enough. I own a MS250 and I love it. It’s my go to, my favorite.
I have a MS-250 it’s hard to start too.
I got 2 at work and one at home. Love these things!
She said that. She knows the MS250 has a high compression engine, therefore hard to start. She even said she's careful who she sells them to as in what they are doing with the saw and makes sure they know it does pull hard and they need to take that into consideration. She's saying that it is unusually hard to start, even for an MS250. Should watch and listen to the whole video.
I believe an easy start was available for this model when it first came out.
ms391 does that once in awhile sometimes pulls no other times rips cord outa your hand.. owner replaced coil.. im thinking its not in spec on coil
I have rarely used a chainsaw. I watched this video because it seemed interesting. This person was very engaging, knowledgeable, and interesting to watch. In the end, she placed the responsibility for not checking "the small things first" directly on her shoulders. I live in South America where it is shameful for a person to admit they did something other than perfection. I love people who are strong enough emotionally to understand that we can't all be perfect all the time. Great job, and if I had a chainsaw that needed servicing, I would hope to find someone like you to work on it.
Your sweet, thank you!
Agreed!

Not on you! I worked in the service field for motorcycles, lawn and garden equipment, generators, etc. What I learned and it saved me a lot of time was while I was writing up the ticket and talking to the customer was, "what did you do to try and fix it?"
9 out of 10 that was where the problem was.
Great vid. Excellent presentation. Very methodical. Just remember a lot of times is if we're not making errors, we're not learning. Thank you and keep up the great work.
I like your no BS methodical approach to resolve the problem. Nicely done
Thank you!
One thing that I have found as a Stihl Technician, is that you need to make sure the cylinder has some fuel mixture in it. Just a small squirt will not flood it but lubricate it and prime it to start easier. Always hold the interlock and the throttle wide open and set to full choke if you are not prep-priming the cylinder under normal circumstances. you will notice that even though the choke is fully closed, the throttle is open somewhat. This reduces pulling tension needed to turn the engine over faster and with less difficulty. 1 to 3 pulls is all you need normally with full choke. If the saw "pops" then immediately, without touching the throttle, move the choke lever to half choke. If you have per-primed with a small shot of fuel into the cylinder for lubrication this is where the choke needs to be in this sequence. Now the throttle is still open but not fully choked. This makes it even easier to pull with both butterflies open. The saw will usually start very quickly with just a few more pulls. The engine RPM will race so be quick to pull the throttle to fully release the choke and lower the RPM as needed. As we work on these saws we learn the interlocks both at the throttle and in the linkages to help us start these powerful tools.
Yep! Exactly the correct starting procedure! Was taught this first day 20 years back on the correct way to start the MS250.
^..^~~
Good Lord! I've never saw a more methodical fix that the lady does! Absolutely fantastic job!
Wow, thank you!
@@marriedwithsmallengines Agreed, I like the straightforward, no-nonsense approach.
Now if you'll come here and fix my old McCullough (old age, needs the primer kit)...
Yeah, she could do or be anything she puts her mind to, I bet. Husbands a lucky sob --hellavu good woman right there.
@@ReziacIf you ever need advice or parts for Macs there's some good folks in the McCulloch thread on Arboristsite who are more than happy to help.
Excellent repair vid! I love that you guys keep things simple and clear without a lot of annoying music and frivolity. Thank you Erica for taking us along on this learning experience. I love working on chainsaws and have been doing it for quite a few years and I learned something today watching you troubleshoot this 250. Another job well done. Good work lady❤❤
Thank you so much for your wonderful comments!
Exactly. Well said. No-frills precision & clarity. How refreshing!
Great Video 💯♥️
I'm 82 years old and had to give my 14 year old MS250 to my 32 year old grandson. The saw was hard to pull from day one but I lived with it till last year. No problem starting...just hard to pull (no decompression valve) which is a common complaint with the MS 250 when looking around the net.
Replaced it with a MS250 C-BC Z/18" bar easy start system. Now its a pleasure to use.
My grate uncle owned a Johnson sp 49 chainsaw year 1984 he was age 73 and smoking cigarettes I was age 15 I use too have too station the chainsaw for him too work it strong compression
I bought my wife an MS180C with the easy-start feature, She'd be unable to start it without that.
I have a 42-year-old, Stihl 028 Super that I first used for commercial timber thinning, running it very hard for 10 hours a day, seven days a week, for three years. It is now relegated to brush clearing around my property and other light duty. It has never had a rebuild, but occasionally becomes hard starting. A simple, quick carburetor clean and overhaul has always solved the problem and makes it run like new. New to your channel and this was very informative, especially pressure testing the fuel system, which I didn't know about.
Thats a good run !
Small stuff first big stuff falls in line.Very fun to watch .Knowledgeable,enjoyable, informative. Thank you !
I have had a husky 142 for 15 years. Used lightly for pruning and firewood. It became hard to start and wouldn't run. I was really puzzled, dismantled the carb. All looked good, but no dice. Finally I tried adjusting the H jet, and yeah it now works like new! So happy that I figured it out, and fixed my baby. A chainsaw is like a dog! Cheers from New Zealand😊

You beat me to your comment!!! LOL

Yep, im a Setup/Floor Technician at my shop. Anyone tells me they are having a problem and they start going off about checking this this or that. I begin at ground zero. It may hurt their ego because they think u dont trust them. But i cant tell you how many times, they say it wasnt this or that because they looked at it. And it ends up being something very simple. Obviously he didn't say any of this, but wanted to act as if he didnt break the seal. So he could hopefully get it under warranty, unlikely being an old saw. But ego's are big when it comes to chainsaws! People hate to admit they were wrong or that they may have made a mistake. Especially if its a female repair tech. Some guys cant accept that a woman may be more mechanically inclined than they are... So unfortunately we've all been there. So basically start at ground zero and do all the simple checks first. That dont require new parts for replacing them after checking them out... at least without first discussing the added costs with the owner/cudtomer anyways.
My MS250 is a great little saw. It’s the first saw I grab when I need to do a quick cutting job.
Thank you for showing us through the trouble shooting process. I’ll remember it when its needed🙂
Like how neat your shop is, how professional and knowledgeable you are, and how well you narrate and edit. And you look beautiful with your hair down, a nice touch at the end of the video.
Thank you so much!
When you had taken the saw out without the bar and chain, you can hear the drag on the throttle response. I always hit the carb first when I see ready mix fuel. As for the special tool for the piston, use a pull rope this way your not messing around with a flashlight. You are spot on talking about the compression on that saw. It will rip your arm off if you don't find the sweet spot.
I worked on a Stihl 046 and it also was a hard starter. I am 73 yrs old and it would try to pull my arm off. I rebuilt it a couple of times, replaced the crankshaft, piston and cylinder. It is one of those saws that wants to pull your arm off. So I made an electric saw started . I took a 1/2 hp electric motor that can run both forward and reverse. I machined an adapter that matches the flywheel pull starter. (you have to remove the pull starter housing.) I engage the motor/adapter to the chainsaw and I have the electric motor plugged in. I have a foot switch that has a momentary contact switch installed. You engage the motor and saw, step on the momentary foot switch and the electric motor starts the chainsaw with very little effort. It sure beats letting the chainsaw beat me to death. When the chain saw starts it automatically disengages the chainsaw. I use this tool on saws that are hard to start. It lets me figure out problems without wearing me out.
Good advice right there "try not to put your tool in the wrong hole"
Before removing your nuts
He he! Good advice. 🙃
Every time I try that, I get slapped!!
I hate it when that happens
11:52 in case anyone missed it haha
Thank you for being a female doing this video. I’m try very hard to do everything I can since my husbands works a lot . I try to take care of the yard . I just appreciate a woman doing this video (and I’m thankful for all of the hard work real men out there )!
Starting my chainsaw, I use to put my foot through the hole where the hand to operate it normally goes. The Chainsaw doesn't jump around then when you pull the starter cord.Easier too.
Tiny feet or pointy boots ?
Hard with 17EEEE lumberjack feet.
@@user-xh5ei4vl8g
YES! Why is it that the handles of all chainsaws are just a bit too small to get the toe of your boot into the handle? They all need a bit of a redesign; perhaps all the manufacturers assume that people drop-start their saws. I never do that because it seems dangerous to me.
Great video, thank you . I have a MS 250 and it runs great with no complaints. I pull it over on choke slowly the 1st time then the 2nd pull with the choke still on I do it full speed and it fires up with out riping the recoil rope out of my hand.
Excellent demonstration of problem solving and methodical approach to a service.
Go Canucks, you're awesome.
That grin was priceless when talking about installing the piston stop tool
"That's what she said" Lol!
Nothing worse than getting your tool in the wrong hole.
I scrolled through thinking nobody was going to make note of that😅 I guess there's more adults here than I thought
@@pcallah3442I thought the same thing, but I'm a dirty old man.
I also have a Stihl battery saw and it always starts very easily, has no fuel issues, etc. My go to saw for firewood. My sawing technique got better as this saw does not like to be forced at all. It will do the job on its own just fine. I can carry it in the car for blowdowns on the driveway and the roads.
I bought my MS250 from my local JD Dealer, Last one in stock before they put out the new ones with bulb - I have a pre bulb MS250 and it ran sweet for many years, always started always ready to go. In last couple years it started running and stopping after 5 min. then progressively in same day in next 4 to 5 starts would run less time each time till just would not start. Took to shop and replaced coil. sweet again but after about 10 min. it did same thing, I opened it up and realized if they had put a new coil in it, it should be a little cleaner than it was for only making about 15 rounds cuts on 10" trees. I purchased a coil and replaced coil - it could be slightly out but close enough and should not die as it had been like plastic housing warming up and wires disconnecting in coil - only thing left is carb. shops around here are so un-trust worthy - want new gaskets etc. - iam a difficult customer i hear now. still possibly need a carb . I have done shelf fuel, and Non Ethanol mixed with Stihl synthetic mix small bottles 1. gal. mixtures. 2 new air filters, 3 plugs, 2 fuel filters - all on top of what originally i had in it when problems arose. ( Plus new fuel lines, electrical came with coil i put in. Iam about 50 bucks away from having spent what a new one would have cost. I actually bought a new one at ACE and it would not start a second time when they were pre fuel and starting it for sales so I ended up cancelling that CC transaction and re done because of warranty's then they had another and purchased that one, seemed all good, left- picked up mini excavator and headed for little property 45 miles away - saw would never start, it popped once and that was it. needless to say i took it back-manager would not except it so i left it on counter with papers and said CC will be stopped payment and never been back in last year. This brings me up to my age and hand- finger size- unable to put a carb on and stuck with finding a good shop, I even have 5 carbide chains and 2 extra roller bars , been using a HF chain sharpener so about 4 years ago I bought an Oregon sharpener and am quite good, I have a few guys whom are fire wood cutters ask me to sharpen their chains- usaly 8 or 10 at a time a year- I feel honored and the 8 bucks a chain is good - Iam retired disabled vet. i have a lot of free time but not a lot of time.
Watching your video is a good example of why I don't loan out my chainsaw. Borrowers don't take care of equipment. I remember my neighbor telling me a story about loaning out his chainsaw out to somebody , guy returned his saw but didn't tell him he had burned raw gas in it !
Excellent presentation! The MS 250 will be my next chainsaw. Thank you. 👍
Now that is an example of a tech doing their job. Sure she had a self inflicted issue, stand up any of you who have never, my butt remains firmly planted. The customer was returned a working chainsaw, the mechanic was smart enough to to relearn a lesson and we have been treated to 23:30 of professional, exemplary work with a pinch of wry humor. Subbed, this was terrific, thank you.
I have a Ms 250 and I hadn't have any issues yet but thanks for the help and I hope you have a wonderful week I had learned something new today
Thank you very much, have a great week yourself!
Thanks for the tutorial, I have two MS 250's that do this when they sit awhile and when they do start they smoke, I'm a older guy and I'm almost afraid to start these arm breakers, I just ordered a new Echo just so I have a saw that does't try to hurt me.
I bought one of these a couple years ago and it was impossible to start. I returned it immediately.
You know i just found this channel and found it very helpful. Im a disabled vet whos recently started working on 2 cycle stuff, chainsaws, weedeaters etc.. we are a stihl dealer and i got my bronze but no where near silver. I get very disappointed in myself when i cant diagnose something right off the bat,i realize i overthink things way to much. Im pretty much on my own i have no one to talk to regarding whats next scenarios so i really get frustrated. Thank you for your time in doing these and please take care.
Hi! I am so glad you are here and thank you for your thoughtful comment. It's very easy to overthink these repairs. Sometimes (like in my MS250 vid) you just have to stop and go back to the basics.
Thank you! You are a good instructor. I have one of these saws and now I have some idea of what to check.
Well done video. It's now in my MS250 tool box. Thanks!
Well presented, thank you.
Most Excellent work. Well done young lady, well done. Thanks for the lesson. 😊
There's no need to appoligize. This is what I consider learning. Thank you for the awesome detailed work. You taught this lawnmower owner quite a bit for chainsaw motor repair.
When she said “I’ll take it owtside” I thought Canadian? Then when I saw the snow yip!
Sometimes when you can't find your sunglasses... check above your brow before leading a search party. Have been there many times myself. Good or bad days.. it is always great to be alive. Thanks for sharing Erica. 👍
Thanks for watching!
Happened to my buddy yesterday at work. Right on top of his hat. Oh well.
Brilliant! It is always a surprise to me that these 'simple' 2 stroke engines can be such hard work to fault find and get running well!
great instructional vid, cheers.
Thanks for doing your videos very informative
very good tutorial. you're spot on about arm/shoulder ache from some of these machines and if you ever hurt your shoulder like I did pulling on a stubborn saw it's months before it heals properly.
I have two of these and love them - when they start, that is. I gave up on that aggravation and got an 80 volt electric from Harbor Freight. GREAT decision. Cuts great and battery lasts a long time.
Learnt so much from you, very methodological and well explained, thank you😊
Nice work. Excellent presentation. I now know a lot more about my Stihl saws.
My 1st time ever seeing you and your videos, your awesome I subscribed!
Thankyou for such a great video. You are humble and honest and informative, three aspects i need to watch a video to teach me about my saw. Bravo!
Just goes to show every day is a learning day. Carburetor seems to be the most common problem. With chainsaws. These videos are fantastic can't thank you enough for showing them keep up the great work.
You do an excellent informative video....Thanks
Excellent video. Thank you.
I'll be watching lots of your videos! Excellent clear explanations. I which I lived close enough to bring my saws to you for tune ups. I hope young folks are watching to see this would be an interesting career and they recognize this is a level of professionalism to strive to reach.
This is by far the best demo/instructions video about checking the chainsaw without any BS! Amazing, keep up the good work!
Wow, thanks!
Very well explained .You are a true professional
Thank you .
I have run mine wide open since I got it. Never failed to start once!
About 8 yrs old.
Never changed the plug. Use only Stihl mix period.
Have changed the rope once. Been throught 10+ chains.
Fine saw for me. But I only cutup trees that have been blown down. Lot of that here. Cuts them up great!😊
Excellent video. I will service my saw based on what I’ve seen. Thank you.
Very nice video ! Bought a Stihl chainsaw with easy start , smooth running chain saw .
I am digging your channel!! great work great tutorials exactly what people need
Thanks so much!
When putting your piston stop tool in the spark plug hole, you can remove the exhaust muffler and look into the exhaust port and make sure that the tool does not protrude the exhaust port. Keep up the good work.
This is the most awesome video I have ever seen on CZcams. I just love shows like this and a mechanic chick.
Wow, thank you!
Very through, thankyou for your detailed examination and repair
Good information and well explained. Yes I have a 250 and yes they are a hard pull , but its a great Chainsaw and a beast cutting a whole tree with ease .
Very good video that explains a lot of problems.I had with hard starts on saws
Down here in my àrea of the U S the Sthil ms 250 is a popular chainsaw so I clicked to your vid & paid attention 😊
Really thorough well made and inspirational video! Your cool personality makes all the difference.
Greetings from Sweden
Very organized shop. You seem knowledgeable on 2 and 4 cycle equipment. Helpful content enjoy watching you're channel.
Wow, thank you!
cool to see your shop and approach to working on saws ... I'm glad I found the channel!
Absolutely brilliant and very informative video 👍
This is a great channel. Have viewed a few videos and definitely impressed with your presentation and wisdom. You've earned a new sub. 😊
Just stumbled onto this channel … very informative and thx for posting… I appreciated your systematic analysis.. I certainly wouldn’t have guessed that the issue was the carb.
Excellent thorough video! I subscribed!
By the time you spent that much labor and parts, I’m betting the bill was as much or more than the saw is worth. I have two 250s that have the same trouble, one especially bad! One was given to me by my brother who gave up on it, and the other I bought at a yard sale for $10! Both are great little homeowner saws. I’ve found that when it kicks, it’s saying “I’m ready, take the choke off”. Couple pulls and it’s running!
I have several other saws, all Stihl, but my very favorite is a little 023 that has several hundred hours on it… worn out, very little compression, but still starts easy, runs good!
Enjoy your videos, well done! Thanks for sharing!
Yep. I have had the same thing happen with mine. Have been careful to take that choke off at the first sign of a hard pull. Also, for the infrequency of use, I have found the Stihl premix fuel is well worth the money. It has been no trouble with the premix.
My 250 does the same thing. I noticed that 2 pulls is enough, even when it doesn't start. Turn off the choke and 80% of the time it will start on the 3rd pull.(On daily use. It could be different if the saw didn't run for 6 months)
I thought it was the flywheel key also. Thanks for the tip on keeping my tool out of the wrong hole, that will keep a guy from getting into alot of truoble!
No problem 👍
Great video. Thanks!
Nice job repairing the saw. I just found your channel and enjoy watching your videos.
Excellent video thanks!
Top job on this vid , thank you , cheers
I have a Stihl 032 that had been giving me same problem. Ran well but took two arms to start. (I made a starting board to hold it down with two feet while starting.) I hadn't considered the coil, so cleaned and gaped it yesterday. Wow, I'm 79 with a shoulder replacement. It started like it was brand new. Thank you for the informative video. The saw is about 44 years old and I heat the house with wood so it gets a great workout in southeast Michigan.
i us the dropsaw method to start ms250 . when its warmed up i hold cord and saw shoulder hieght and thro tha saw away. just for fun. 91 octane fuel and 38:1 mix .
WE need a John Force version of a chain saw fixin video..
i am about 400 miles North east of u . and i like my new electric saw just fine. 🐺
I'm subscribing to this channel. Great video. Love the small engine shop videos. Nice walk thru explanation on this video. Thank you
This chick knows her stuff!
Thank you!
Very interesting and informative..😊
Bad ass
Take away notes never put your tool in the wrong hole especially while fishing in the dark.
Great educational vid by a seasoned pro. Thank ye!!
As a Stihl technician and owner of an MS 250 I can tell you they are a very hard to pull saw. I sold a lot of them but always cautioned the customer that most women, elderly or folks with a bad shoulder should consider a different model. If you don’t pull it like you mean it it will jerk starter handle out of your hand. I always thought that a larger diameter rope pulley would help this.
A decompression switch would help more.
@rickringler5021. See, if you had been my dealer I would still be a Stihl customer. Too many of them just don’t give a crap when a homeowner walks in to buy.
Enjoying these Stihl videos, just rebuilt two 036 Pro saws and they are just awesome tools. Great video!
Right on! Thank you for being here!
I'll be watching all the chain saw videos. That's for sure.
Thank you!
When I heard the symptoms my first thought was flywheel key.
Good perseverance to get it fixed.
I wasn't going to let this chainsaw beat me!
I'm putting my Stihl in the yardsale. Piece of shit. Plus my dealer was a real dick.
My Husqvarna chainsaws never fail and never break an arm.
I have a 250 that has a partially broken flywheel key. It lines up fine, so I’m thinking that will work for now… I still can’t start the thing, however! I even replaced the two seals. I guess I’m going to replace the carb next!
I also thought for SURE that it was Sheared as well ... but then my only real experience of replacing them is on Lawnmowers .. Never seen one actually sheared on a Stihl Chainsaw.... but the symptoms certainly matched .
I had an old 041 given to me years ago that had a sheared flywheel key. Have no idea how that happened, but a new key and it ran fine again.
I’ve always kept my tool from dropping in the wrong hole. Thanks for reminding me nonetheless.
Good video verry well explained.
What a good video Mrs ,really thorough and helpful!
I collect saws and love working on them and all the different vlogers on saws have different tips it's a great community ❤️🙂
Glad it was helpful!
Very good advice.
Always, always check the carburetor(s) first. Good for you Erica for doing the full check down, though you did forget the carburetor, but, you got there in the end. Good post.
Great job! love the channel.
thanks , young lady... you do good work
Great video. As a mechanic also just a tip lol leave your wedding rings home so they stay clean 😊. Keep up the good work
Everything I see gets a dry and wet compression test and an
Endoscope viewing.
Good find on the carb issue.
Also, I feel your pain with customers not revealing the true history.
Awesome video. Thankyou
Glad you liked it!
The video was very Good can't wait for more Thanks
Glad you enjoyed it
I bought a brand new Stihl cutoff saw about 10 years ago. A month after owning it we couldn’t start it. Brought it back to the dealer. They put a new carburetor on it. Didn’t have a problem after that
