My Stihl MS250 has been a phenomenal saw for small tasks but lately, it has been running poorly and is difficult to start. Today I take a look at it and decide if a new carburetor is needed. Let's see how it runs with a new carb !

Usually you can order a oem gasket and diaphragm kit and keep your oem carburetor ( its usually a high quality carburetor). Old gas or a much used saw eventually wears the pump and deteriorates the diaphragm. A good cleaning and fresh diaphragm almkstxalways fixes them up. Cheers from West Virginia

@EverydayProjects 9 месяцев назад

Good advice, thanks. I have the tools and an ultrasonic cleaner at home and a rebuild of the OEM would be best, but I’m visiting far from home and the cheap carb swap was one of a few options. Great advice though. Thanks

@joew9392 6 месяцев назад

The design of the starter (small pulley) makes almost all the ms250s seem like they have high compression. If they re-designed the starter it would be a lot more user friendly.

@EverydayProjects 6 месяцев назад

You're right. That's a great idea!

@DacaTimberworks. 6 месяцев назад

I bought mine off an old man on marketplace. He had such a hard time starting that little saw that he constructed a jig to hold it down while he tried to start it lol!

@robertlehrman5832 16 дней назад

I replaced my carb, fuel line and filter, spark plug, and air filter assembly. Probably same kit you have. Carb works fine. Hose was easier to replace than my Craftsman. Still need to do a little adjusting for it to run perfect. At least it starts now.

@EverydayProjects 16 дней назад

@@robertlehrman5832 Glad to hear you got it going. Sometimes, the carb kits come with an adjustment tool that fits the mixture screws. The low speed jet keeps the saw running at idle and works along with the throttle adjustment screw. Adjust a warm saw while running until it idles smooth. The high speed jet manages the fuel at full throttle. Adjust it while holding the throttle open until it does not bog down and runs at full throttle without bogging. Sometimes better and safer to remove the chain first. Good luck😀

First time watching your channel that Calibrate, I need a little adjustment.I use them all while and I always have to make the necessary adjustment

@OpenAirAdventure Месяц назад

Mine will fire up at half choke. They flood easy. I didn't bother changing the carb, I just flooded it with brake clean and let it sit for the day. Im running high test fuel to avoid the ethanol because the 250 sits for months on end.

@EverydayProjects Месяц назад

Good tip on running the premium fuel. This one sits a lot too. I only use it when I visit back East once a year. I actually mailed it to myself from BC. It cost just under $30 to mail it and have a saw there instead of borrowing (not a habit I like) or renting a saw when I need one. Thanks Kenny....be good!

@EverydayProjects 3 месяца назад

The only problem I found in the replacement one is the distance between the mixture screws, but cutting off the rubber piece that allows access to the screw heads was all it took to make it fit. Some have suggested just cleaning and placing new gaskets in the original carburetor, so don't get rid of it. Maybe you can put a kit in it as a spare. Best of luck and thanks very much for watching. PS- WOW I had the gas mixed way too rich...probably 10-1 hahaha Take Care

@GardenTractorBoy 10 месяцев назад

Perfect timing, we need to go through our MS250 and I suspect it needs a new carb. Great job on the saw

@EverydayProjects 10 месяцев назад

Thanks, Joseph. These aftermarket carbs are very good for the most part. Good luck with the swap on yours. (PS: make the cameraman handle all the dirty parts so you can keep your hands clean) LOL

A buddy of mine has an old 250 that the last time I was talking with him was having issues , I will send him this video, and he'll probably give me the saw to look at so I'll pay attention now lol

@EverydayProjects 8 месяцев назад

Old gas gums up carburettor and sometimes, it's easier to just put in a cheap, aftermarket one. This one from Amazon was less than $30 and fixed the saw like new! I hope your buddy will pay you for your time. Fresh-caught baloney roasts are the currency we use LOL

Usually there is wear on the accelerator pump of the carburetor, this is a common problem on the Stil 250, you can simply turn it off, but I replaced the carburetor with a new one hello from Siberia

@EverydayProjects 9 месяцев назад

Thank you for this information. I kept the old carburetor that I may someday rebuild ( having the original is often better) but changing it out for a new, aftermarket one was inexpensive and quick. Thanks again for your comment. Hello from Canada !

@EverydayProjects 10 месяцев назад

Your MS250 may need one of the carbs someday. I still remember your FREE file story when you bought your MS250! So funny that he charged you for the file LOL (That's probably because he heard you don't like squirrels).

If that guy knew I didn't like squirrels he would have given me the saw but probably still charged me for the file!! LOL@@EverydayProjects

I’ve had my ms250 for 5 years and I’m honestly not happy with it. I got it because of the size, not too big and not too heavy. But I’ve always struggled to get mine started. Yes! I I put it on the 1st choke setting til burps and yadayadayada and I’m wore out by the time I get it fired up. This is one of the few things I’m ready to give up the fossil fuel for their expensive electric ones. The thought of just clicking in the battery and go cut is too tempting.

@EverydayProjects 4 месяца назад

I've heard other say that too. The MS250 can be difficult to start, however other than the carburetor issues on this one, I find mine has started well and has been reliable. I've had this saw for about 10 years. Maybe the newer ones are manufactured in a different way? I know that some newer Stihl saws (designed for fuel efficiency) like the MS291, are hard to start when hot, and it's not because of faulty coils or ignition components. It's the ported design of the cylinder. I happen to own an MS291 and it gets little use because of this issue. The MS250 was always a good, small saw but maybe they've lost something along the way. Cutting costs at the factory ? Design changes?

@jamiejohnston4983 3 месяца назад

Yes I've seen this a bunch

@donmoore7785 Месяц назад

The MS250 I bought in 2007, and the second one I bought in 2023 both start reliably - third pull on full choke fires, 2nd or 3rd pull on half choke it starts.

@EverydayProjects Месяц назад

@@donmoore7785 It seems like some of the MS250s are prone to hard-starting problems. This one works well now that the carburetor has been updated. It sits for months at a time without use and even with fuel stabilizer and running it dry before storage, it can still gum up. I think the starting issue most have is to due with high compression. I know that they made a modified (easy start) model, perhaps because of this. It seems strange that such a small saw would have compression issues that make it difficult to start. Also, the design of the starter, with its small diameter has played a role. Looks like you got a good one.

Nice work - thanks for sharing. Im waiting for the same replacement kit and hoping i have as much success as you did.

@SteveRobReviews 10 месяцев назад

Awesome 👍 Lots of compression that's for sure. I mix it 50:1 , whats your mix about 25:1 😉

@EverydayProjects 10 месяцев назад

I think the mix was 1:1 LOL it smoked a lot but I did have some storage spray in the cylinder. Thanks, Steve!

@ttommytom Месяц назад

@@EverydayProjects Use the spark plug hole as compression release. Pull plug, pull the cord 10 or so times and the compression is gone for awhile. Not a mechanic so I don't know why these 250's have this issue. Obvious why it works. I did a muff mod 12 years ago. Bad gas mileage but a different chain saw. It's not embarrassed to hang with my 362. Sounds better too...

@ichsan-purwadi 6 месяцев назад

You dont have to buy new carb. The carb only need to be cleaned. It happen to mine.

@tuckerandi 8 месяцев назад

Very informative and you still have all your fingers 😅 I rather mix it rich as well and have to change a smoked plug than have a saw overheating or have a scored cylinder or piston.

@EverydayProjects 8 месяцев назад

Agreed. I'd rather have a saw smoke a bit than to prematurely wear the piston/bore.

@honorlite4060 9 месяцев назад

It is better to use original spare parts. Chinese fakes are usually of low quality, but in your case the carburetor works fine, which is good. I would also advise checking the maximum revolutions on the tachometer; they should not exceed 14,000 revolutions.

How many turns does that carburetor have in the L and H screws?

@headcheese777 Месяц назад

The problem with your saw was the diaphragm. no need for a whole new carb

@EverydayProjects Месяц назад

Dear Headcheese, You're partially right. A diaphram most likely would have remedied much of the problem, but it wouldn't clean out the small passages throughout the carb. Swapping out the whole carb is fast and the original can later be rebuilt properly (with a thorough cleaning, new diaphram and gaskets). I plan on disassembling the original and placing it in an ultrasonic cleaner then rebuilding with new parts. These videos aren't a one size-fits all solution, just one of many ways to get the saw up and running quickly. Thanks for your comment and input. All the best! Craig

@stevenkinnison8044 5 месяцев назад

That flexible rubber piece that goes between the cylinder and carb is the intake boot.

@EverydayProjects 5 месяцев назад

I've never had to change one of those boots and I have several Stihl saws, some many years old. They can deteriorate but I've not had to change one yet. Good that they included one with the Carb kit. Thanks for commenting.

@DIYVariety 10 месяцев назад

Ms 250 is only a weed eater lol but you got her going buddy,

@EverydayProjects 10 месяцев назад

These are great little saws and so handy for small to medium-sized work. The problem is that the carburetors get gummed up eventually and make them run poorly. A simple carb swap for under $30 made this saw run like new. I always use storage spray in the cylinder and condition the fuel, run it dry and store without gas, but they eventually gum up anyway. So nice to have it working while I wait by my mailbox for my surprise you brought me back from your trip!
