Congratulations on showing the adjustment while making test cuts. Sooo many guys do not do this. Well done brother.

Bought a new Husqvarna. It kept stalling. Used this video to help me tune it and it runs/cuts like a champ. Thanks for posting this!

This was the best adjustment video I’ve seen. Doing it while cutting was key point. I had all the problems you showed

You nailed it! Direct and to the point. No extra talking. A you tube video that is USEFUL. Thanks!!!

Very well done! Clear explanations and great camera shots...answered my questions and got me thinking in a logical progression. Thanks for the video

I would make my own adjustments...trial and error...you'll never learn unless you try. Thanks for another great vid!

This was very informative, thanks! To answer your question at the end, if it came to messing with the carburetor, float valve, I’d take it to an expert. 😀 But now I feel informed enough to try those initial adjustments on my own. I like your “if this, then that” diagnostic approach and tutorial.

This video is by far the best I found on youtube; very thorough and concise. Thank you much.

This is the first and only vid I've found that addresses this problem. Thanks so much, perfect for a learning user like me! I recently found a poulan in my shed and want to use it as a carburator adjustment practice saw for when I eventually get something bigger than my MS170.

Thank you so much for helping people like me that really want to know how to take care of problems ourselves!!!

Exactly the issue I have with same model of saw. Thank you for a clear, sequential solution to tuning the carb. Great video and helped me get my saw back to running smoothly.

I was looking to fix a certain problem with my saw and ended up finding the solutions for other questions I had concerning my saw . All in one stop , Thank you, great video

I have the same saw having the same problem. Thank you for the video and the clear, concise explanation of how to make the adjustments.

Got to tip my hat off to you friend. A very informative and thorough video at that. I wasn't expecting the saw to "die out" under pressure (cutting the log), I thought it would work just fine. Thanks for adding that in. Well, I'm off to give it a shot. Thanks again!!

Rebuilt my whole carburetor and still was having these exact issues. Very helpful video! Thank you!

I adjusted mine. It was new. Started, but lifting up or cutting chainsaw would die. Now it runs great!! Thank you.

It helped me greatly, making the idle adjustments while running the saw . I needed to see it done. My saw has been bogging down, now I know what to do . Thank you

I I have learned how to work on chainsaws by using videos on how to to the repairs I have all of the tools needed to do the repairs Still learning something new every I watch a Video I am very thankful that you fellas take the time to put these awesome repair videos it just as good as a Small Engine Repair Course I am very grateful to every one that puts these videos up I TRULY THANK YOU

Many thanks for this excellent video. My Husky has this problem, so I'll try the lo & Hi adjustements & order a carb kit as well. I've cleaned the carb, air filter, exhaust flame arrester & fuel filter in the tank.

Great tutorial. I'm in the midst of adjusting mine now!

I have tried several approaches to adjusting the carb on Poulan Chainsaws, and can't seem to find a good setting. Your way of explaining it has helped me understand it better. Going to give it another try. Thank you.

It’s getting to where even if you take your saw to a saw shop, you still end up working on it. I would rather utilize a video like this and see if I can fix it first. Even if you just replace the carburetor, it’s cheaper than the labor you’ll pay to have it worked on. Thanks for the great video!

I've learned alot for being a new chainsaw owner. Had the same problem, cut a few times and it would quit on me. Awesome video and it was clear and concise. Thanks

Thanks just what I needed... I cleaned the carbs from both my 141 and my 365 but had a hell of a time tuning both saws.

After watching you do it I feel comfortable giving it a try. Your explanation was excellent.

Best video I’ve seen one how to tune the carburetor on a chainsaw. Thank you for the great information.

Logical, well thought out and calming demeanor. Thank You for your time.

Wow. I gotta try this .... Thanks for being clear and consise and not holding the camera in your hand while you were filming. Great edit

‼️Thank you so much for making this video, you just saved me a boat load of money 💰 by not having to take my Husqvarna to the shop & buy firewood ‼️ ‼️I made the timing & throttle adjustments on my 435 18" Husqvarna chainsaw because after 14 years of regular maintenance & running great, it started stalling when I started cutting, made your recommended adjustments & now my Husqvarna is running like new‼️ ‼️You can watch me use my chainsaw after the adjustments were made, on my channel after I post it tonight - 1/28/2023‼️ NEWCASTLE CALIFORNIA,USA 🇺🇸

Excellent video! Exactly as determined by the circumstances. Logical sequence of fixing the issue.

I have to say. Thank you. No one on u tube would explain the adjustment. I've cleaned and nothing i did the adjustment and runs fine now thank you

Love this video. I'm new to all this. Thanks for explaining it the way you did

Hi, thanks very much for your help I have a 130 saw and it was running everyday over winter. I put new chain on and saw was dieing at high revs. I have adjusted carb like you showed. Working perfectly. Thanks from a warm fire in Ireland 🇮🇪

Wow, just what i am experiencing. Your video gave me the confidence to do it myself. Thanks Boss!!

OK I ran the saw today and made a couple test cuts and made a little bit of adjustment. Used it the rest of the day. Thanks again, you have saved me much time on a good saw, that needed attention.

Brilliant and useful explanation especially the typing explanation as the saw ran. Thank you.

Nice work best video I've seen so far on adjusting a chainsaw and testing it out at the same time is awesome. I need to work on my Husqvarna and I can do this before I go ahead and take the carb off to clean or rebuild it. Thanks again you're the best. 🤗🇨🇦

I will try and tune my own saw from now on . Thanks for sharing .

Just wanted to say that I appreciate you posting this how too. I recently purchased a used Husqvarna 235e and it wouldn't stay running after a few cuts I received a ton of advice from friends, but none of it was consistent. The only common ground and cheapest fix was the carb adjustment. At first I was waaaay intimidated by doing this. From what I have heard it is easy to mess this up and have a hard time readjusting it, so I never thought I myself would feel comfortable doing so. Unfortunately, I had few people that sounded like thet knew what they were actually doing. I watched this video and felt confident and compelled to attempt to adjust it myself. Well long story shorter, it worked! It idled and ran fine untill high engine speeds, I simply turned the h screw one quarter turn counterclockwise to increase the fuel delivery at high engine speeds and it fixed the issue! I understand a little bit more and feel way more comfortable with two stroke engines and how to adjust their carburetors. Thank you for that!

Yes, I would tune L and H settings myself. My chainsaw is older than yours so I would see about replacing the metering diaphragm, even if I got it running okay. Thanks for the tip!

Yes I tune all of my own small engines but I've learned a lot from watching your videos

I'm having this issue with 2 brand new 120s. Thank you so much for the tutorial.🙏

I will definitely do this myself. Super helpful video. Mine stalls when chain brake is applied.

Yes after this video I would test this on my own saw. One thing you should say. That if you open the high end too much. You can and may blow the saw. If you have to open the high end that much rebuild the carb and save your self blowing the motor. This was a really helpful video. Thanks

Thank you for this informative video which explained the various aspects of throttle idle speed (chain moving), low and high speed settings. I have a Husqvarna 240 and it did that cutting out/dying thing day one right from the store. I did manage to get the carb adjusted myself and got it to work properly. Just wish I would have found your video several years ago! lol. Great job explaining everything and good camera work with everything in focus and not shaky or jumping around like in other videos. I saved this link for future reference.

Great job on the diagnosis

Nice and informative video. My near brand new Craftsman 18" that has ran for years now and then, but I would bet not a whole gallon of fuel has been through it yet. It looks very similar to this one. Last time I used it, I completely forgot to run it dry after pouring out any fuel in the tank like I usually do. Yes, dummy me. I know better, but still it happens. I needed it the other day for a small tree and found I could push the prime button several times, choke it, and it would crank up and run fine at high speed for several seconds, then die. You could prime it again and same thing would happen. Big bummer.. None of the lawn equipment repairs shops here say they will even try to repair a Craftsman. They say to just trash it and go buy a new Stihl for $189 plus tax, but they are 2" less on the bar cut. I just hate to throw away a very new chain saw just because it won't suck fuel out of the tank.... Their has to be something I can do to try and fix it. A friend said maybe the fuel line got clogged or has a small air leak that keeps engine from drawing fuel from its tank. A simple fix with new fuel line might work?? I'm not a DYI or mechanic on a lot of things except a computer network or PC I can fix most anything. Lawn equipment? Not so much. But why throw it away and not try something is my thinking? What do I have to lose by trying? Nothing but a little time. Since it runs fine on primer fuel, it still could be carb. adjustments needed like you did in this video. Maybe not. What you think is the best thing to check first and then later if that doesn't work? Joined your KZfaq channel. I expect you will have many tips and DYI stuff for me in the future. Thanks for doing those. You can comment here or send directly to my email at dgrubb001@gmail.com.

I'm going to give it a go myself as this video has given me the confidence that this Is exactly what my saw needs. Hope my metering diaphragm isn't caput!!!

I have a Stihl 026, which is basically the same as the newer MS260, and a Husqvarna 61. I have adjusted the carbs several times due to weather conditions, starting problems, etc. Your video was very informative! However, if the metering diaphragm on the carb is hardening why not just replace it, along with the carb rebuild kit. It's an easy task on most saws.They aren't very expensive. And, from my experience, once the diaphragms start to harden, the problem only gets worse. And sometimes you get a decent Chinese replacement carb, and sometimes you don't... The aftermarket carbs work better on larger 4 stroke engines. I've had much better luck with them on 5hp motors, like lawnmowers (particularly Honda lawnmowers, and pressure washers). These small chainsaw carbs are so finicky, the aftermarket carbs tend to be more trouble than they're worth, imo. One more helpful tip for your video: USE ONLY ethanol free fuel and good 2cycle oil on small engines!!! And ALWAYS run small engines dry before you put them up, unless you're going to use it again within a week of storing it (like lawnmowers, and weedeaters, during the summer, etc).. Otherwise, you made a great, Informative video!! Especially for those who are afraid of adjusting a carb!!! Kudos!!! Gave you a thumbs up, and subscribed.

Your video is what I was looking for..thanks lots of information in it...I'll look at it several times and attempt to adjust mine...metering diaphram...diagram... might have to replace that...thanks so much for making the video

I feel very comfortable doing in myself now thanks to you. 👍

Very helpful. Husqvarna T435. First, it did not work. I cleaned the muffler. It was very quite blocked, spark arrester and all. After reinstall, I adjusted again. Works fine. Thanks.

Excellent visual presentation demonstrating diagnostic process, solution process and results.

Great video, my Dad and I had the exact same issue and dialed in the fuel… Saw works great again… Thanks for sharing!!!

That’s the exact saw I need to tune up. but I think I will rebuild the carb first. Thanks for the tips.

Thanks for the help I just got a brand new Husqvarna saw this morning. Mixed the gas with good quality 2 stroke oil so I knew it wasn't that. I had chain oil and the chain wasn't too tight. It started pretty easy. I warmed it up then shut it off and walked into the woods then it kept cutting out when idling. It slightly annoys me that the manufacturer would allow a brand new saw to be tuned wrong because not everyone has mechanic experience. But yeah the video was really helpful thank you.

I am going to have another look at my chainsaw and have a go at this. Thanks!

Hot damn, thanks.. been trying too figure out why it wont stay running 😕, you hit the nail on the head point blank my Brother... thank you sooo very much, i now have a working chainstick again..

wow that was awesome i kinda new how but now i know how alot better than i did because how you went step by step better than other stuff i have read or watched thank you

Very good video, tried it and help my chain saw improve performance. Thank You.

Well done. I like to do what I can myself. Not every tech is savvy and sometimes you're better off at least trying to fix the problems yourself. At the very least it's good to have some basic knowledge of how your machines work.

excellent! Thank you! I'll look for your video on replacing diaphragm too!

Great instructional and I will definitely make my own adjustments. Thank you! 👍🏻

It must be a small world, as I have the exact same model chainsaw which I just put a new carb on and it does exactly the same thing as this one did when you started, so I really appreciate this video and Ill try this out and hopefully it will work out good. Thanks-

Not sure if this was said elsewhere in the comments but I wanted to suggest that you really cannot say that the fuel had too little oil in it based on color these days. Today there are various oil manufacturers that make different colored oils (stihl and echo are two that come to mind) as well as all the pre-mixed fuels being different colors. Not saying you are wrong. But I would think it is pretty unlikely someone would know the oil content UNLESS they knew what oil (or premade fuel) the customer used and had enough experience with that specific combo to judge color. Thanks for the video. It was a good watch.

Thank you. This is helpful. I was unaware of the high-speed mixture adjustment. Mine seems to work fine for about 20-30 minutes cutting and idling but then bogs out like you showed in your cut part of the video. After this I cannot get the saw to start at all. It starts the next time I choose to try the saw from fully cold beginning the cycle again. I have changed the plug figuring it fouled but it doesn't change the cycle. I was considering a possible ignition issue since I cannot see the spark with the plug removed but grounded. I will try these adjustments though. I did buy this new about 3 years ago and maybe have 10 hours on it.

just bought the 440 off a friend for $50, it wont stay running. Gonna try all this stuff and hopefully I can get her up and running! Liked and subscribed.

Exactly what i needed. didn't want to bring it back to the shop again. Now if i can figure out why my bar nuts keep loosening in the cut and fix that i'd be solid

Good info. Thank you. my 435 is doing something similar to this but it could be anytime before it shuts off. I could cut up almost a whole tree before it shuts off or I could be a few cuts in and it would shut off. Will try fiddling with the carb a little to see if it helps.

Very good explanation and demonstration. Thanks.

Great video. Clear instructions and video. Thank you.

Thanks for this information, i got the 120 Mk 2 and the chain keeps spinning. So now after watching this vid i got the correct answer i need to tune mine.

Fantastic, just what I needed to know, thanks mate👍

Great video. Going to try it now. Mine has exactly the same symptoms

Very helpful. Off to try and adjust the H counterclockwise 1/4 of a turn...

I personally would make my own adjustments. of course I do most of my own work on things unless it's too much beyond my own ability then I may need to seek out someone else to do it. Thanks for this great video!

Thanks this should save me a trip to the shop.

Thanks so much! Very helpful! I was about to give up on my chainsaw before i saw this :-D

Excellent and most helpful; thank you!!

Nice video, way more to the point than most of them.

I dont knownif its just me but this is the best video I have seen on this.

Thanks for the info, I'll defo give it ago when needed.

Thanks for the tutorial. Bringing my Wild Thing (no jokes plz😉)back to life after a couple years of inactivity. First, was changing all rotten fuel lines. Next was through cleaning of entire machine and a general very close inspection. My first attempts at running would last from 3-5 seconds. Looked for your vid and fully expect good results tomorrow. Thanks again.

Thank you, clear and concise.

I will do this first thing tomorow . Good video man !!

Great video i'd try almos everyting to fix my echo cs 400 chainsaw ti'll i watch this it'd works for me the only thing i'd remove the limiter caps on the carb. Thanks my friend you save my chainsaw.....

Best video I have seen on tuning your carb! I bought a new carb recently for my 235e and when i start it runs for a second; if i try and push the trigger it dies. I think i will play around with the gas at low speed first to see if i can keep it going. Do new carbs come tuned or do you have to tune them yourself?

Thanks! low idle was my problem.

Great video, thanks !!

@INSIDE HOUSE GARAGE Hey buddy, just found your channel and subscribed because your way of working/thinking is so much better (and better explained) than all the other chainsaw and small engine channels on KZfaq 😁👍 The reason I clicked on this video is because I have a 15yr old Stihl MS230 that's done the work of 3 pro-grade saws over those years, but last Summer I worked it really, really hard (a 4'-5' diameter willow had fallen over/into a creek at my Dad's place during the covid lockdown and I couldn't work, so I needed to do something just to stay (semi...) sane...) and it just hasn't been "right" since then... So it'll fire on full-choke, then cut-out, which is 100% normal for a Stihl. Then when I'd flip it to the 1/2-choke position and pull the starter it would always fire and run at fast-idle with the chain running relatively slowly until I blipped the throttle to cancel the choke, and then settle to idling with the chain stationary, like it should do. But now once it fires on full-choke and dies, when I set it to 1/2-choke and pull the starter it runs for maybe 2 seconds and dies again... Opening the throttle makes it die, leaving the throttle alone makes it die, and it seems to be not getting enough fuel to run for any longer than that? I've stripped and thoroughly cleaned every part of the carb twice, and the diaphragms appear to be just fine (still very flexible, no hardening, leaking or cracking), the jet is 100% clear, I put a new fuel filter in the tank in case it was blocked, blew-through the fuel-line with my compressor to clear it, but it still won't run... I've re-set the carb to the factory settings and tried tuning it (following the video on Steve's Small Engine Saloon) which is what led me to your channel, via Donyboy's video on the same topic, and here I am... Now I realise that you can't magically help from what I've told you above, but would really appreciate some of your wisdom and advice please? -I'm in the UK, and all the pump gasoline here is either 10% Ethanol (Regular) or 5% Ethanol (Super), and the pre-mix fuel here is just crazy-expensive (like the same price per litre as Jim Beam whiskey 😳), but the Stihl Super-Duper Ultra High Performance 50:1 2-Stroke Oil (the blue stuff) that I use (with 5% Ethanol Super gasoline) claims to work 100% effectively with all European gasolines up to 20% Ethanol, according to the sticker on the bottle, and Stihl UK say that I need to take my saw to my local Stihl Dealer "to be tuned", which will take 2-4 weeks and cost me the same as buying a new saw, so I'm not gonna do that... Do you think it's the fuel that's the problem (rotting pipes or diaphragms in ways that can't be seen by the naked eye), or do I have a crank-case leak or something like that? Or is it just that the saw is so old now that I need to remove the limiters from the carb-adjustment screws and start the set-up again from scratch, using my digital 2-Stroke tacho so I don't blow it up? I've just got a Zema carb rebuild kit (it's a Zema carb) in the mail that I'm going to install today so that might solve the problem, but like I said I've stripped the carb twice in the last week and everything looks just-fine, and I've been working with 2-Stroke engines on-and-off for 30 years since I was 18 and never been beaten by one yet, until now.... So... Any advice would be massively appreciated 🙂, and please keep making your excellent videos because like I said above, I'm REALLY impressed with your work 😁👍

I accidentally left my (less than a year old) Husqvarna outside over night a couple months ago...well, it rained really heavy that night... Yesterday was the first time I've used it since then... And yes, she didn't want to stay running after some cuts... Thought maybe she got some water in the fuel...but then also noticed that it was basically out of bar oil.. I will revisit this video soon if after replacing fluids doesn't solve my problem. Great video by the way!

Great video mate.

Nice carburettor tunning

Exactly my symptoms. My 372xp runs great in idol, but as soon as you put it on wood, it dies after or during that initial cut... I'll have to let you know if this fixes it. (Somewhere in the garage is hiding that kit of Husky carburetor tools!) Appreciate the video!!!

Thanks , it helped me tune mine.

Good show. I'll be back to follow your steps when I attack my sick saw

Not gonna lie I dont usually like or subscribe but ur videal really help me thanks soooooo muchhhh

very well explained. thx. i feel confident to try now. thx

Very informative, thanks.

Awesome video!
