Stihl MS-290 Questions.

All good brands saws have

 

The needle in the carb stuck for a moment , this is why the saw do this , its a stupid problem today will do it tomorow maybe yes maybe not , its not a problem if you see it deeper its only a bad moment.
just clean the carb or change a needle

 

You just need to clean and inspect the carb first ( in your case metering side ) then and if no problem you can tune it , i tell you before the carb needle sometimes stuck , the results is poor acelaration or the saw die . Then after a few bleeps to the throtle the needle unstuck and the saw run fine.
so tell me what you want to tune the carb ??????????? if first you dont repair the problem

It does indeed have the warm/cold shutter. You have to pull the plug boot and flip the rubber stopper to the appropriate symbol (snowflake, or sunshine), as well as flipping the plastic angle thingy from the solid to the meshed side.

That being said, I'm confident that that is not your issue. I'd be willing to bet the majority of 290 owners have no idea this option exists and never have an issue.

 

It sounds like the 290 that I had for awhile. It would start easily and then go lean and bog out. If you could get past that point, it would do OK.

Turns out that the fuel line had a small crack in it just before it attached to the carburetor. A new, genuine, Stihl fuel line solved the problem. The Aftermarket line that I tried first kinked so badly in that spot that it wouldn't pass fuel through.

How a saw can start easy when it have problem to the fuel line ????

 

I would be fearful of something causing the saw to go lean, which will burn a saw up very fast. If you do not have a way to check then it may be worth while to find a good saw mechanic to check it out.

 

My friend looked at the saw. The first thing he did was to check the fuel; I am positive I mixed it correctly. He mixed new fuel and the saw ran fine; the symptoms I mentioned were gone. I am thinking that the alcohol in the fuel reacts in some way with the oil. I am going to buy non-ethanol fuel and use it in my saws. I have a weed trimmer that does the same; the fuel sits just for a short while and turns dark and the trimmer runs poorly; with fresh mixed it runs fine. Has anyone else seen any issues with ethanol fuel and the mixture turning darker after a sits for a couple of weeks?

 

I always put STA-BIL Fuel Stabilizer in my 6 gallon can that I use for everything, it helps a lot

 

So now the saw start and run fine correct ?
And your friend change the fuel and now the saw run fine correct ?
But with your fuel mix the saw dont start and have problems correct ?

I bet you 100 euros that a saw ( if its in fine condition ) can start and run even if you put bar oil to the fuel mixed 50:1 if you want , also i think that you know that a saw can start even if you forgot to put oil to the fuel
So maybe your saw likes your friend more than you

 

Yes, that could be it

My friend poured the fuel into a clear glass container and said it looked too dark. I am sure I mixed it correctly but I suppose I may have read the fuel container wrong. By the way, the saw would start with me and my fuel. It would bog down when pressing the throttle. It also wanted to continue to move the chain around the bar at a fast clip when just sitting. I outlined all of this in my original post. I just followed up to let everyone know it was the fuel and nothing wrong with the saw.

 

HAPPY END

 

Me saw, no run chit, bar oil in fuel tank

 

Exactly.... Yes the 290 has this. You may need to flip it to the other setting. Easy peasy

 

I've run ethanol e10 in all my 2 stroke things and I've not seen that happen. I've been running e10 for about 20 years. My 029 super may have never had anything but e10 in it, ever. OK, I've run some trufuel because I wanted a small container. I've never had an issue.

 

One day one of my dears butchers customers phone me and say , i am in forest and the chain dont stop thing that i have leaks , then he come after two hours , he start the saw . the saw start perfectly but after a little the chain start to run . i open the fuel cap and see a black fuel and a black filter
i ask him what is this ? he tell that he have a little more woods to finish but he dont have more two stroke oil so he put bar oil to the fuel
the crazy is that the 361 start fine and full throtle perfect, after i check the saw i find seals leaks , and a hair leak from the impulse
but the saw can start

 

Most of them are real saws butchers , they work for companies the companies buy the saws from the stihl , husky in very low prices , they use the saws for one or two years and then new ones thats the deal they dont give a sh.... for the saws because they dont have pay for them , at the other side the companies make black deals with the goverment ................. complex jobs .....................................
