Stihl MS250 bad bog and fix…

If your chainsaw stumbles or bogs and will not run right. Adjusting the mixture screws doesn’t seem to fix it. Here is how to disgnose and fix it.
*Here’s the Amazon link for the special tool you’ll need to adjust the carburetor. It’s a 12 piece kit that comes with a bunch of other tools to adjust and repair/clean the carbs on chainsaws/weed trimmers etc.

Just want to give a shout out to you. My MS250 which is about twenty years old was doing the same thing as yours, bogging down whenever you tried to give it throttle. I bought a new carburetor for it, installed it, and the problem was solved. Thank you very much for the help. I really appreciate it!

@bruceludwick8200 right on did you buy the carb right from Stihl or aftermarket?

[@bruceludwick8200]

I bought a Stihl carburetor from the stihl dealer.

[@Indeewoods]

@bruceludwick8200 ok It should last a long time. Hey what fuel were using in it? Just regular or higher octane? Any ethanol in it?

[@bruceludwick8200]

Used regular for years. Non-ethanol became available a few years ago and I always use it now.

[@Indeewoods]

@bruceludwick8200 right on ya I’m pretty sure that 10% ethanol in the fuel was what took out my carb check valve.

Great video man.. Sounds like you got it set right- I can hear it 4 stroking at high rpm's then smoothing out into a 2 stroke in the cut. That's how I tune all of mine. Thx for the tips!!

[@Indeewoods]

@markyakubovsky3380 right on yep thats the way to tune them
