I was having low power from my saw as I tried to figure out what was wrong. My saw is the same model as this one. I spent the day cleaning the carburetor and not cutting wood. I saw your video and checked the screen on the exhaust and found it to be plugged just like the one you showed in video. At first soap and water, that didn't work, tried alcohol, didn't work. I used Lucus injector cleaner, it worked well. Thanks for sharing the tip, it saved downtime and didn't need to take it in for repair at shop.

Checked the spark arrestor screen after watching your video and found it to be plugged solid, just as in your video. Cleaned up the screen with some carb cleaner and now the saw runs like a charm. Certainly appreciate you sharing this tip for trouble shooting. Cheers.

Hey good job on finding the problem! Carb, ignition, and plugged fire screen all yield the same issues with these engines. I'm a mechanic on saws as well and carb or plugged fire screens are the most common problem. And the plugged fire screen is normally caused from the customer not running the saw full throttle, or like you mentioned running to much pre-mix. Have fun!

Learn proper jet settings. Step 3... Maybe go back and adjust the needle valve lever thingy properly. I think it may be a little off still. Walbro 247 = .65 - .70. But first... exhaust. Finger crosses and the wood is ready.

Speaking of the bar - flip the bar over everytime the chain gets removed. Helps keep the wearing of it distributed to both sides. When re-attaching the bar, put a slight upward pressure on the bottom of the tip of the bar while tightening the it.

What ‘very expensive irreparable damage’ would it cause? Why do you think the engine would overheat? You also can’t over rev the engine, short of just holding it wide open for a long time. Chainsaws are designed to rev, and newer ones all have limiters in the ignition. It’s a 2 stroke engine, not 4 stroke.

Thank you ! I'm a handyman guy and occasionally I've done some backyard mechanic stuff for over a half century. I've worked on all kinds of motors, but never had I come across a motor that uses some little screen over the exhaust. I had looked all over the internet to try to figure out why my small chainsaw was bogging down. Who would think there would be a little screen completely clogged with carbon. I cleaned it off and it's running great now, especially because I put a new spark plug in it. It's just a little Stihl ms150c that I use for cutting branches. Using my larger Stihl for that wears me out. Thanks again.

It's a "spark arrestor". I cut logs for 22 years and they tend to clog up on you. It was something that you can do without. The reason we had it was because the worker's insurance demanded we have it . They would check it randomly . But if you take care not to cut wood with the muffler too close , you can just take it off. It is meant to prevent sparks from the muffler to which to this day I have never seen happen.

I run a bunch of Stihl power tools daily in a commercial setting. We always take the spark arresters out. The eventually clog up irrespective of a correct mix or not. We absolutely mix the correct ratio. My guess is, they only put those on for liability reasons. Maybe so Stihl dealers can make minimum 30min- one-hour labour charges and diagnosis fees for a two minute job, for something very obvious to those who know.

Good information.... also remember to check the fuel line in the gas tank. If regular gas is used, then it might have ethanol and that breaks down the rubber in the gas line over time.(94 contains no ethanol.)Then at high demand, full throttle, the line can collapse inside the tank and the saw bogs. Easy fix by simply replacing the line with new one. (I had to wait to have my new gas line delivered so in the meantime I used a steel spring from a pen as a stent in the line and it worked perfectly.) Stihl is a great little saw.

I bought a Remington back in 2013 used it for wood cutting, then skipped a year, using just my electric heat.. 2015, I got the Remington out and it wouldn't start very well, finally got it to start then by holding the choke open a little it would idle but if I tried to throttle it. It would die. I just went out and bought a Kobalt 80volt electric. No more gas/oil mix or yanking on ropes.. Anyway good video.. BTW, I sold that other saw for $1.. The guy later said that he couldn't get it to run either.. If I see him, I'll pass this info on to him to check this.. or I might try to buy it back for 50 cents.. lol (he was my cousin or it wouldn't have been $1)

Great video on the importance of checking the spark arrestor screen. An often overlooked piece on a chainsaw by many. It was nails on a chalkboard for me to hear you peg and even briefly hold that throttle just after starting. If this becomes a users habit it will lead to cold seizure scoring of your piston & cylinder. Newbies & construction guys (infrequent users that just wanna get to cutting once started) are notorious for cold seize scoring a chainsaw. Let your chainsaw warm up before pegging that throttle, ladies & gentlemen. It will keep its power we & last much longer if you do. That holds true for any motorized device including your vehicle.
