Stihl Chainsaw help

Okay, I felled a black oak tree in my field last week. The tree was dying so I'm making firewood out of it. I started sawing up the log and everything was going fine until I got about halfway done. My Stihl 290 MS died like it ran out of gas. I filled it up and choked it. It started but when I switched the choke off, it died. Tried 4 or 5 more times and can't keep it running. Checked the air filter and it was pretty dirty so I put a new one in. It's still doing the same thing. Any suggestions?
Thanks.

Carb is probably clogged or a fuel line is collapsed.

does it have a screen as well as a filter ? look for a set screw on the muffler .

send it to me

Spark Arrester is clogged. Take muffler off and remove screen.

My Husqvarna had same symtoms. Turned out to be a pinhole in fuel line causing it to suck air. Started fine but as soon as choke was off it had too lean a mixture and died.

Lots of YouTube videos on this here is one.

Keep us posted what you try and what fix.

Take a look at your fuel line...especialy the part thats inside the tank.....they are fairly easy to replace.

Call your son and tell him to come finish it for you or you will cut him out of the will. Then throw the chainsaw away so you don't get yourself in this kind of pickle any more.

You're welcome.

2 things to check: make sure none of the fuel lines have a hole in them. The tiniest bit of air getting in the fuels lines will cause that. If not, the high speed jet in the carb is probably clogged. Might could put a kit in it but Stihl carbs are cheap. You can get get a new one for under $50.

I just bought one for my Stihl weed wacker. It was about 20 bucks shipped.

And another thing....make sure you are using FRESH fuel. Amazing what havoc a little moisture in fuel can cause.

And a higher octane fuel.

Trash in the gas--

I had the same model stihl doing the same thing,my problem turned out to be a burnt piston.I hope this is not the case for you.

Speck, You need to hire that stuff out so it wouldn't happen to you!

You’re probably right Barry. I like Wannabe’s idea. Get the boy over to finish it.

My MS 290 didn't sound like it was running right. I removed the hood to see the air filter had 1/2" of dust on it. I thought about washing it, better read some tech about it first. Scrape across to remove build up, don't poke. Spray across filter with carb cleaner and air, not toward. Clean area with carb cleaner and air before removing filter.
I thought about changing the filter, not at $16. I went to ebay, 6 for $8. We have 2 MS 290's and a MS 310.

Trash in carb sucked through that nasty air filter. Trash in the high side . mine did same thing .

Check for clog muffler first or bad gas or air filter bad fuel line I use chain saws a lot had clog muffler a few times hope you get it going

If I had all your money I’d go to store and get a new saw and been through cutting up that tree. Just bring me old one next trip down and I’ll scrap it for you.
