stihl ms250 chainsaw cold start

- The stihl ms250 chainsaw can be tricky to start if you do not follow the advised routine - there is no fuel bubble and over priming/flooding can lock it up causing some hard hydraulic lock to pull through. The way to start from cold is 2 pulls full choke , 1 at half then start on I setting (run setting). Hope this helps you. This is not the quick start version. The wood in vid was cut previous day.
Good clear video advice. Have had MS250 for 10+ years. Mine starts like this:
1. Chain brake ON.
2. Full choke (right down).
3. 3 pulls. Usually fires briefly on 3rd pull.
4. Move Choke to half (1 click up from bottom).
5. 3 more pulls. Normally starts on 3rd pull.
6. Brake OFF, control saw, run for 10 secs with throttle on.
Ready to work... usually!
Stay safe.
Saw arrived yesterday th-cam.com/users/postUgkxfQm1wmg0ItKDLavxj1nXtQY9HP7EF504 and today I cut about 3/4 cord of wood with it. Make sure you get an extension chord that is at least 12 gauge wire, minimum. This is my first electric in about 10 years, and things sure have improved. The self-sharpener works great, and it just kept cutting through some pretty decent logs. Wear your eye protection, and ear protection. Excellent saw.
MS 250 hardest chainsaw to start i ever used in 50 years of cutting
Just bought this chainsaw. got it home yesterday and couldn't get it started for the life of me. Was going to take it back, and watched your vid. Did the steps you said and it started right up!!! THANKS my friend, you saved me alot of hassle.
I just purchased this saw with high recommendations from our local shop, which I greatly trust. This morning, I tried to start it and it was a no go. However, I used to have a MS-210c, which I HATED for the first year. Then our Stihl vendor showed me how to start it, and it became my favorite.
I just did exactly what is shown in this video and my new saw started with no trouble at all! I think this is the beginning of a beautiful relationship...
Thanks for the tutorial!
You were straight to the point, with no extra jibber jabber.! I went outside and started my saw. Thank You! Great video.
daxio 14, you are the man. I've had a stihl 250 for over 10 years, never could starrt it. Would take it to shop they would start it and say no problem. But dammit no one ever went through the steps like you did. YOU ARE THE MAN. MANY THANKS. I've used it 5 time since watching your video.
Glad you posted this. I bought this SOB early last summer and I have less than 10 hours on it. It is very difficult to start and floods so easily. I will attempt to use it this afternoon based on your tips. I'll post back tomorrow hopefully with positive results.
Great help in getting my saw started! Following his suggestion on how to start at each choke position. Went to the garage, cleared out the chamber, dried the plug and reassembled. Started on the first sequence!!
Thanks for restoring my manhood by stating the MS 250 can be tricky to start. Works like a freaking champ once its running, but when you only use it 2-3 times a year it can leave you scratching your head. Now to go un-hydro lock mine
This worked like a charm. Wish I had watched this video on the weekend when I had my son here with his truck to take away the debris. But watched this and decided to give it another try and started on half choke with the 2nd pull. Thanks for the video.
You provided valuable information for many of us who experience the same challenge. Forget the critics. At least I appreciate it.
It's not the chain saw its people.i just bought one the other day and if you just follow instructions it will work.its a badass chainsaw I gave a heat session yesterday and the MOTHER KEPT UP WITH ME.NOW THATS A FINE MACHINE
Got rid of my MS250 due to hard start problems and bought a MS290 farm boss to replace it. I could use the MS250 for an hour and then turn it off and spend 10 minutes trying to get it started back up again. Did a total service on it and still had hard start issues. I have around 10 stihl chainsaws and love them but out of all of them the MS250 was the most unreliable.
Thanks for the straight forward/clear description - I appreciated the true cold start and explanation.
hi - the chain oil is very easy to identify - when you touch it , it is sticky and stringy - it is normal to lose a little - in fact it is a good test to check that your oil feed to the chain is not blocked with sawdust (also you should learn how to take apart the chainsaw and clean it) - to check you just rev up the chain close to some dry wood and you should see some small spray of chain oil.
Good show Daxio14. I would have never got my saw running following the manual (as I interpreted it.) Your technique was perfect and got me running. Thanks for posting!!
You did the starting procedure mostly correct, except for the last step. The proper way to start this saw (I have the same saw), is to set it on full choke and pull until it just starts to fire up/turn over. Then, just like you did, you flip it up to high-idle (turns choke fully off). Then, you pull on high idle until the saw actually starts (not just once like you did). The reason you do this is because leaving it on high-idle keeps the throttle trigger partially depressed, where as "run" does not, which is not optimal for cold starting.
I can start my MS 250 in 4 pulls or less EVERY time.
I have a Stihl 250 chainsaw which I purchased because it was suppose to be the best chainsaw according to many I talked to in my area. I already have an older Poulan chainsaw which I purchased in 2000 when we had several ice storms during that Winter here in Arkansas, but it was getting older, even though it gave me great service, and still does. Since owning the Stihl 250 new I have not gotten a good hour's work out of it, and the saw have spent many times in the local repair shop. I recently purchased a new Poulan Pro saw to help me around our rural home. I have not gotten to use it yet, but hope it is as good, or better than the old Poulan saw. The Stihl is just collecting dust since it seems to be impossible to start.
Strange
I found this very instructional. Thanks. A buddy of mine, who is a long-time Stihl user, also told me to shake the saw upside down a few times before a cold start. Believe it or not, it seems to help. Of course, once the saw is warmed up, it starts on the first pull. It's just that first time when cold......Grrrrrrrrr.
This was really helpful. I've had my MS250 for 4 years although it has been mostly idle for the past 3. I ran it a few months ago without problem and then let it sit with Stihl Motomix in the tank. Over the past few days I've been unable to start it. Not even a burp. At first I thought it wasn't getting reliable spark. Then I wondered if the Motomix was bad. After watching your video I realized I was clearly flooding it. Followed your steps and got it running. I don't know how they can call this an EZ start model. I miss the 362 I sold 5 years ago.
1st I suggest using 93 octane fuel with the sthil 2cycle oil mix and ethanol free gas!This saw is one tempermental piece of equipment.I have found If you flood the unit remove the plug then 2-3 pulls to clear the cylinder and then blow off the plug or use some brake cleaner.Wiping out the carb area of any residue does help.Reinstall plug and retry in the 1st choke setting then start position.Personally after only owning this for 7 months since 10/13 this is a bad model and so wish I had chose a different model or brand at this point.The end statement is the overall reviews and specs this model is hard to start,and or keep running or restart after use.This should be the ms250 migraine seriously.
Thank you, this helped me. Simple, but useful information for me as a beginner. Disregard negative responses.
chainsaws use quite a lot of chain oil - its not like a car where you top it up once every 6 months or 1 year, if ever - with a chainsaw you need to top up the chain oil every 2 or 3 tanks of gas - and do not forget to mix the 2-stroke oil with the gas!!!
Thanks. I was having trouble starting after 3 days of un-use, but now it works fine. I buy the pre-mix 50:1 gas/oil mix from Lowe's.
Put lever fully down. Pull until fires. Push lever up 1 level to high idle. Pull until saw runs. Pull trigger and saw will idle normally. Easy, quit making it harder than it is
Obviously you have an easy starting one.If you read reviews you will see you are the exception. Or maybe you're a young weight lifter that doesn't mind pulling on it twenty times.My MS250 never hints on starting when on full choke, and if you pull more than 1 or 2 times on full choke it's flooded.Then it will take at least 10 pulls on FULL open throttle to clear before it fires. I'm here to find an easy way.
@@bobarmstrong2122 the starting procedure to any non m tropic stihl chainsaw is exactly the same! Easy start variant and normal start variant! Easy start mechanism is make it easy to pull the cord, actually you are not feel the compression of the engine but the easy to start mechanism tensioning a spring who will start the engine for you
Mate - quality quick video explaining simply what all the commercial (US mainly) vids don't get to. Good lad!!
Good man! Thank you, problem solved. After two days of flooding it, I'm back to cutting up the trees I dropped last fall.
*If you need a rugged, heavy duty saw but you are not a full time professional tree cutter this model will fit your needs>>>**ur2.pl/723** It has all the power you will ever need to cut through any type of wood up to about 3 feet in diameter. And it costs about half of what a pro model would and has a compression release to make it easy to start, especially for old timers like me. I have used it for one season so far to cut about 60 cords of hardwood with no problems. Would definitely recommend.*
nice chain saw!
I used ms170 for a long time, never had an issue starting them, needed a stronger saw got the 250, now I'm having a hard time with the Hydraulic lock, locks up on the first pull then floods afterwards
at airshows and for a new engine start they do it to not only check for hydraulic lock but to also circulate oil around the engine
Wow just learned something. I've been starting mine without choke with about 5 pulls, woops
please note: In the video I started the saw the first time with the chain brake OFF - not a good idea in case you slip or stumble - better to start with the safety brake ON = HANDLE AWAY FROM YOU - but be careful not to rev the engine too much if the brake is on as it burns the brake.
hydraulic lock for your info is when oil seeps down into the cylinder and remains at the top of the cylinder filling the space of the top of the piston creating more force to turn the engine over which can ruin an engine just like that.
A lot of American aircraft fitted with radials had that problem because young techs just jumped in and started them without draining the bottom cylinders thus causing hydraulic lock. sometimes they turn the engine by hand on the prop to check for hydraulic lock.
Depending on the weather 2-5 pulls on full choke til it fires, move lever to half choke and it usually takes 2-3 pulls to fire up at which time you BLIP THE THROTTLE to bring it back to idle. If it takes more than that your saw is out of tune, you're not doing it right or both. Owner MS362,250,170.
I put an ngk plug in mine and it seems to start way easier
helpful! worst stihl I've owned.
very helpful, good discussion of choke. helped fix my problem of starting my saws
yeah, i was young once and probably shouldnt have been running a saw, but was, the throttle was hung up somehow or another wide open with the chain brake on, it slowly started slipping and smoking real bad. i shut the saw down and freed the throttle and tried again. the brake is still fucked up to this day. little "brrrrps" that this guy is doing is fine. it is part of our equipment checks at our firehouse to do that. rev with brake, full throttle and apply brake. its what its made to do
Hardest starting saw I ever owned.
I tried that and it didn't work. What I ended up doing is pull out the spark plug, dry it with a paper towel, give the cord a few cranks, then put the plug back in. After a few more pulls on normal run setting it sputtered a bit and then came back to life, putting out a lot of smoke in the process. I use medium grade fuel with 50:1 Red Max oil (I also use this for my Red Max blower). I also add a packet of crystalized stabilizer each time I fill up my 1 gallon gas container.
Presumably you can damage the engine if you rev with the chain brake on?
And now the really correct way: Full Choke untill it fires up for the first time, lever one click up on half choke, it will start on half throttle -> pulling the throttle lever and it will automatically jump into the normal running system :)
Exactly. I've had my MS250 for several years and I have never had a starting problem following those instructions.
Thanks so much!
haven't tried it yet, but i will tomorrow, i definitely didn't know bout that. tricky sun of gun!!! good saw thou
I have problems with mine year after year. No matter if I run the best gas with it or not. I think I may have bought a lemon.
what kind of problems you having?
Did it get easier to start with age?
Yes, I guess. Had to service the carb that''s about it.
Solid vid for newbs not used to no bubble. All you chainsaw pros knocking it should get back to mowing lawns are you really that proud?
I hate this chain saw. My hands hurt from trying to get started. Yes I followed instructions blah blah blah.
Buy an electric one, but just saying the Stihl ms250 is one of the best chainsaw on the market !
Best to the point explanation that works every time. Thanks!!
Shout the break be forward or backward?
Give the bubble any day.
This saw Rocks!
I have a 250 and it is difficult to start gets really jerky when you pull it. Anybody know why? It does not get much use I do use the fuel in a can and try to use up all the fuel.
Thanks! This was so helpful!
Maybe your next video on how to set up your phone to film a TH-cam video.
you are dead right about the 250 going in to hydraulic lock if you flood it. really, it is a function of temperature and humidity. if the temperature is lower than the humidity you can flood a stihl saw in a heartbeat. cool days and high humidity means you are going to have problems. warm days with low humidity is a piece of cake. the 250 has a greater tendency to flood than, let's say, my ms271 but they will all flood if you get stupid with the cold start setting. thee only saw that I have that will crank, regardless of the temperature and humidity, is ms ms261cm.
The MS251 is my fourth Stihl, and is without doubt, one tempermental bitch to start.
Proper technique be damned, this saw starts when and if it wants to.
I find myself grabbing less practical saws just to avoid this one.
the saw runs great! but i did notice a little oil on my driveway after running for about 2 minutes, then when i put it in the case it left tiny puddle of oil in case., is this normal? the oil does look sticky, when it was running i saw it barely coming off blade.
Another problem I've seen with some Stihl saws is the oil cap leaks. Also it could be residual fuel from the chain oiler that runs out from behind the Bar&chain cover that you don't see.
Can you explain exactly how to clean out a flooded engine? My MS250 won't start and I'm sure its because I unknowingly flooded it. I just got it last week and used it for several days going through four tanks.
Remove the spark plug, more the ignition lead boot away from the plug hole in the cylinder. Give it full throttle (NO CHOKE ) and pul; the cord until you don't see a mist of fuel coming out the plug hole. Dry off your plug and inspect it for any debris. Reinstall the plug and try to start with NO CHOKE and medium to full throttle.It should fire after a few pulls
Hi, just picked up a nice used ms250, thanks for this video!! I am assuming i use 50:1 mix? what kind of oil do i use for chain? can i use 10w30? got alot of that laying around.
50:1 yes - but you have to buy chain oil !! it is very thick and sticky , nothing like engine oil. happy sawing.
This chainsaw is fucking hard to start!! Mine never starts as easy as shown in the video
Ugh. Let’s go Tom!
what about the chain brake???
I have blisters from trying to pull it and cord stop an snap out of my hands...never again,im selling this one an buying a Husqvarna..
Full choke when it try's to fire go to Half choke. then it runs.
Only a brand NEW one will start that easy.
seen some bad instruction before but never as bad as that. Filming is not much better either. I have to agree with Hugh Graham posting.
Ran it one time now i cant crank the piece of shit. Had to get out the 1973 homelite dammmmmm
Find someone to hold your camera.
U need a tripod=)
this chainsaw is a joke junk mine never starts when i want it too it was bran new threw away lol
you should have read the instructions. you are supposed to lock the throttle open when starting. why do the clueless insist on pretending to be experts?
I can appreciate anyone who wants to make an instructional vid. But before attempting to do it, don't you think it would be advisable to consider your camera work (positioning and stability) BEFORE shooting? I have never seen such a jerky, camera-poor video. Next time, try mounting the cam, please.
Yes. Maybe this is he's first time. I think tripods are cheap. & do a lot of beekeeping you tube instructions to help beekeepers at ( WallsBeeMan )
This saw is the biggest piece of shit I have ever bought.
I can’t see shit on this video
Lol you don't know what flooded means
Nice camera work. unwatchable
junk
put down your saw before you hurt someone. or yourself...
I've seen many youtube instructional videos. This one is the worst.
You clearly don’t know how to start it either... Now for your next trick.
