Chainsaw Bog Down - very frustrating! This video shows you some reasons and remedies, but more than anything else it gives you a firm understanding of what is happening inside the carburetor for this to happen. So if you have any of the popular brands such husqvarna chainsaw (such as the husqvarna 440, husqvarna 120 mark ii, or any other petrol gasoline powered saw), the Stihl Mini Chainsaw, Stihl Saw, Stihl MS 250, or any budget petrol chainsaw, then you will find some great advice here to help on the way. Bring the power back to your Power Chainsaw.
This principle works for most types of Chainsaw saws, and the following also helps with Chainsaw maintenance. So, whether you are using a Stihl Chainsaw, Husquvarna Chainsaw, basically, all types of Petrol Chainsaw are valid for this principle, as well as many types of or a 2 Stroke Engine. The Electric Chainsaw, of course, escapes this whole principle!
If, by the way, you are having problems with your Chainsaw Not Starting, then please do take look at my other video, where I help you get back you and running again if your Chainsaw Won't Start, or your Chainsaw Won't Stay Running. • Chainsaw WILL NOT STAR...
If you need a easy to follow video on Chainsaw Carb Tuning. So here I take you step by step should the Chainsaw Carburetor Adjustment be required: / watch

Hi guys I just wanted to Introduce to you my other Channel "Kirkman's Academy" - which i'm just getting started. It's a go-to channel for simple explanations for hard to grasp subjects such as physics, maths and chemistry etc. Here is the link: www.youtube.com/@kirkmansacademy/videos . Thank you so much for looking, and if these topics interest you then I hope to see you the there. Many thanks indeed. Craig 😊👍
This is quite possibly the single most valuable diagnostic video I have ever seen.
Wow. Thank you 👍👍👍
Agreed
Having worked on plant and small engines for years this truly imparts years of experience to those hungry to learn. Well done.
Hi Guys. I meant to mention in the video that the High Jet is usually NOT separate from the main Jet, as in the video I have shown them as separate. Usually, the High Jet adjustment Screw simply adjusts the amount of fuel that comes out of the main Jet itself. I have shown the Main Jet as separate in this video just to try and explain a principle of how Jets and their adjustment screws work. I hope this makes things clear rather than more complex. I'm really Sorry if it has. Also, another thing I should have mentioned is that the examples I have shown are mainly based around a lack of fuel getting to the engine as a cause of engine bog. Of course, too much fuel getting to the engine can also cause the engine to die as well. I will make a future video showing this. Again apologies for not mentioning this. I really appreciate you taking the time to look at my videos. Craig
Loved the video, Craig. You explain things very well!
Nice detailed video Craig explaining how these little carbs work
Have you made the video about running rich yet?
I'm more of a "Visual" type person, and your diagrams help take the mystery out of those tiny little carbs. Thanks!
Me to tinker.,
I've seen some good video's about small engine repairs but I must say this video is tops. I;m a retired Loco maintainer/Motor mechanic so I understand the detailed processes you have covered. Well done.
I have to agree his detailed explanations and diagrams are so clear and concise and not missing any critical information.. cheers to him for this ! this was a great help in my repairs of my homelite xl..
For sure I'm not totally ignorant to engines but I was trying to rebuild a poulan that had sit for 3 years in pieces... this guy taught me alot.
I have been in the small engine repair business for a few years. One can never get tired of watching these videos. This one is well done and one of the better by far videos out here on the net. This is a must watch video for any up comer in small engine repair. Thanks for this video.
Thank you very much! I really appreciate your kind and motivating feedback. Craig
Comprehensive, clear, informative and free of glitz and spin. First class!
Much appreciated! Thank you
You've put a lot of work into this. I wish this information was so readily available fifty years ago. Your information is greatly appreciated. Thank you.
I’ve watched a lot of chainsaw tuning videos, and this is by far the best. Most videos tackle the bogging issue from one possibility only like, “your chainsaw is bogging because your mixture screws need adjustment”. You cover all the possibilities and you do it quickly and concisely without wasting time. Basically as close to a perfect video as possible. Thanks so much for making it.
I am surprised to learn of the complexity of a small carburetor on a garden tool. It's a world inside a world and your videos are the most informative of all I have seen yet.
Thank you very much! 👍👍
The most information I have gathered to date from any class or video on the function of the mysterious little parts inside the carburetor of a chain saw. Well done!
Brilliant tuition! Really appreciate the rapid pace, synced diagrams and complete lack of stupid asides in the commentary.
Bravo.
Subbed and passed on.
Thank you for your kind words and feedback. I really do appreciate it. Craig 👍👍👍
Unbelievable content, I hope this is archived for eternity.
That was by far the best carb-chainsaw related explanation and in-depth video I’ve come across. Thank you. I’ll be passing this one onto a friend, who’s MS391 starts ok but just won’t keep running. No matter the fuel or how much he adjusts the jets.
I appreciate the fantastic tutorial on the chainsaw carburetor parts/mechanisms. This should help me diagnose the ills of this saw.
I'm so glad i came across your channel this year. I feel like i'm doing in class learning with a teacher right in front of me. Every video is very well explained that anyone can comprehend and also down to details like no other with lots of pictures/images and parts of what you're explaining. I love the fact that after watching a video i don't feel like second guessing myself. Thank you for taking the time to do this and share it. Excellent work, keep it up!

Best video content for small engine diagnostics that I have seen on CZcams. Thanks thanks thanks. 😊
You covered every possible scenario in a way that makes total sense! Thank you
Very glad I came across your Simplified yet Detailed description of carb problems and remedies therein.
This is by far the best video I've watched on this subject and I greatly appreciate the fact you took the time to make it.
Extremely well done my friend!
Man now every thing about fuel flow come to my sense, you even cover about carburetor. Thankyou good sir. It's the simplest way you could teach amateur to come to a good understanding about this
Excellent video, You have definitely solved all my chainsaw bogging problems. I know now that if my saw starts to bog down, find the nearest skip, and chuck it in, then buy myself a lovely new chainsaw. Problem sorted. LOL.
Bro this is likely best video on issues i ever saw.. and i have watched probably half a million no bs
Thank you so much 👍👍👍
You are extremely thorough, with great illustrations and a wonderful way of explaining things. Much more thorough than our tech teacher back in the 1970's. Thank you.
Thank you so much for your kind and encouraging feedback. I really appreciate it. Craig 👍👍👍
I saw a chainsaw for only $35 listed in an estate sale ad, so I bought it and all it needed was a bit of air/fuel adjustment. Thank you! I'm so happy. Amazing video. I found myself watching, even after I fixed my problem.
Wow, what a great find at the estate sale! It's always exciting to stumble upon a bargain, especially when it turns out to be something as useful as a chainsaw. It's fantastic to hear that all it needed was a simple adjustment to get it up and running smoothly again. There's something incredibly satisfying about being able to fix a problem and bring a piece of equipment back to life. I'm thrilled that the video was helpful to you, even after you'd solved your issue. It's wonderful to know that the content continues to be useful and engaging. Happy sawing, and may your chainsaw serve you well for many projects to come!
Craig
You are a great teacher. Thank you for explaining cause and effect in such a detailed way. It helps one to know both ends of a problem because it helps you to figure out other problems.
Well worth 17 minutes. I understand so much more about chainsaw carburetors now. I'm bookmarking this video for sure. Thanks.
Nice. A comprehensive checklist of common/easy to next level troubleshooting. This is a keeper.
Thank you for the thorough and complete walk through. I am an auto mechanic but I never really knew about 2 cycle motors or what problems exactly I am looking for with my chainsaw. This gives me pretty much all I ever needed to know.
Excellent video. I had a broken tube from the crank case to the top of the carb. ( Sort of a PCV system ). It was causing a severe lean condition. Replaced the tube and all is well. I had forgotten the 2 stroke intake procedure into the crankcase first to lube the engine. The excellent crankcase section of your video jogged my memory on 2 cyc operation. Thanks Ed.
Nice work! And thank you so much for the kind feedback. Craig
This was outstanding. The diagrams and animations helped me wrap my head around this tremendously. I know its not a quick easy thing to put together, so thanks for all this extra time put in.
A most excellent and thorough video. Here in the states ethanol in gasoline greatly decreases shelf life and increases clogging and corrosion in anything with a carburetor. Fortunately in many places non-ethanol can be found, though at a premium. I’ve started using the jug for my gasoline model airplanes for my saws and trimmers to keep things fresh. Model airplanes are generally fueled by a hand crank or electric pump which can be reversed to empty the tank when done. Doing this also seems to help with power tools when they won’t be used for a while.
Great explanation for troubleshooting and understanding some of the other possible issues besides the main ones like the spark arrestor. Very well done!
I work on small engines as a hobby. And you did one heck of a job explaining everything that could happen everything that could clog up and give you issues. I've had a lot of these issues in the past. Keep up the good videos and I'll keep watching. Very informationable if that's a word. Lol lol😂😂
You covered so many aspects that could cause bog down. Very thorough and explained well. Thank you!
Thank you for your nice feedback. I really appreciate it. Thanks again. Craig 👍👍
Excellent video! As a fellow mechanic (automotive & aircraft), you did a superb job of explaining the why and how. Good job!
hello there,i live in MADEIRA and watch your videos all the time ,keep them up, they are very helpful ,please don`t stop.and many thanks.
Another great video on the problems one can encounter with a 2 stroke chainsaw. Thanks for the information.
Best video I've ever seen on two-stroke carburetors
Wow! Excellent description. Now I have more knowledge than just adjust the high, low, idle screws. Thanks
Nice tutorial! The detailed and colored diagrams were really helpful for visualizing the process.
Best explanation of basic, small engine function I've ever seen! Thanks.
Thank you for your kind and motivating feedback. I really appreciate it. Craig 👍👍👍
I have this exact issue with my Husky 235 that i ment to use for light work around my garden, and this video gives me confidence to start troubleshooting. Never done any engine repairs before though..Very well explained. Thanks!
I want you to know that I really appreciate your lesson. Plus, your illustrations and explaining each element of a carb's function is great.
Thank you so much for your very kind and encouraging comment. i really appreciate it. Craig
Your tutorial is spot on and very explanatory..you do this so well TRS..Thankyou so much, what an expert you are... thanks again...
Best graphic diagrams I’ve ever seen. Also extremely good explanations for those diagrams.
Superb explanation and illustrations. Top marks! Thanks Craig
The best instructional videos on you tube bar none. Keep up the great work 👍🇦🇺
thanks for this comprehesive review of areas to check when experiencing bog down.
Learned a lot! Very thorough and I appreciated the diagrams.
Best small engine video that I have seen to date. Thank you from Canada.
Wow, thanks! I really appreciate your awesome feedback. Craig 👍👍👍
What a great video!
I have my dad's old 1973 Homelite and trying to get it running.
But, I know next to nothing about fixing them.
It cold starts pretty easily but only runs for less than a minute before shutting down.
This video gives me somewhere to start.
Thank you.
What a brilliant explanation I really admire all the work effort and years of experience upon which you base this. It has made my mind up to get an electric saw as I see all these problems and wonder how my saw ever worked.
Great video. I clean the exhaust screen quite regularly on my chains saws and weed eaters. Some models it's hard as the screen is part of the muffler and can't be taken out. Minature wire brushes work here if you can get to the screens. The worst one I have is on a craftsman weed eater engine (which triples as a pole saw and hedge trimmer). The screen was inaccessible, but after warranty period I modified the muffler just enough to be able to get to it with the brush.
Gas quality has gone down in recent years, and don't get me started on ethanol gas. I use a Fuel Stabilizer every time I get a new can of gas. :)
I change out fuel filters regularly, and change gas lines as needed also. Often solves the starved fuel problem.
This guy making this video is so knowledgeable, I do say, it be easy to believe he’s the engineer who designed and had it manufactured. What a pleasure to listen and learn from a true expert. BRAVO!!!
Video well done, too!
Wow, thanks! That’s some really nice feedback. Thank you so much. Craig
Excellent information and presentation.Thanks.
Brilliant comprehensive teaching 👏
Thanks. Clearer and more succinct than some helpful videos. My Huskvarna was working fine but failed to stop without choking. It also began to leak fuel. Took it to a dealer for a new stop switch and fuel line. They took it apart, cleaned the carb and bought a new fuel line but didn't fit it. I needed it back so they put all the bits in a box to let me fit it. It eventually started but bogs after a few seconds. Adjusting the idle screw made no difference. Will now try the multiple combinations of high, low and idle screws and report back in the Spring. It's lucky our cars aren't as complex!
These are the best repair videos I have ever seen
Wow, thank you. I really appreciate it. Craig
Well you have just confirmed what I've always said... And that is, it is amazing how such a small little engine in carburetor can be quite complicated! I did not realize there was approximately 100 different possibilities for why these small engines don't run well! Truly, one of the best and most thorough explanations for one of your engine would bog like that. My weed eater is currently doing this exact same thing. I may give a look at it to see if I can figure it out. Nicely done! Thanks for sharing!
Thank you so much for you feedback. Craig 👍👍
Excellent video.
My son almost had me convinced that I had burned the clutch out but I'm a little older, a little wiser, more patience.
Thank You for this valuable information.
Keep them coming 😃
A brilliant tutorial. Thank you Craig! I now have a lot of knowledge to try and sort out my Huskvarna Rancher 50 bogging down.
All Episodes -for 2-Stroke Carburetors Here. Thanks. Craig:

Best instructional videos on CZcams!👍👍👍 I have learned so so much from your videos! Thank you sir very much.
Thank you for you awesome feedback. I really appreciate it. Craig.
Excellent description
Thanks I learned a lot and my bush trimmer is working again. Will keep this in mind for the next time something breaks down.
Great video. I have three Homelite yard tools all with 20cc engines. They lasted for over 10-years before I started having carburetor problems. Several times I've replaced the carburetors with new ones from Amazon. But these new ones only lasted one to two years. I then started doing overhauls on the original carburetor with new gaskets, diaphragm, metering device, etc. Now it runs great with good throttle response but only for about 10-minutes until it warms up. Then I get the bog down. It comes on gradually and I first notice it due to delayed throttle response that eventually turns to the bog down happening at lower and lower rpm until stall. After it cools it runs again. On my string trimmer I replaced all the parts other than the valve as none of the kits have the correct length replacement. This includes the primer bulb, filter screen, metering diaphragm, metering spring, metering anvil, pivot shaft, gas cap, gas tank, gas tank pickup filter, gas lines, and carburetor to manifold gasket. And the gradually bog down to stall when warmed up still happens. Any ideas what might be the issue?
Have you completely excluded fuel venting malfunction? Crack open the fuel cap when symptoms start and if they go away, there's your problem. This is covered around the 2 minute mark and it may be the new fuel tank caps just aren't that good as the original ones. Just shooting in the dark.
Excellent teaching
Very clear and informative. Thank you.
Excellent tutorial. thanks for posting. cheers🤩
Bogging down was my problem I listed these points and checked through the whole system, After it started first go and snapped it into high rev with no drag Job done Thank you for passing on your knowledge
Awesome. Thank you for letting me know. 👍👍👍
Thank you for the spark arrestor tip! So helpful.
very helpful -I am having bogdown problems
Really detailed and comprehensive.
Good Morning from Idaho, U S A. Very extensive explanation. THANK YOU ! TAKE CARE..
