- CHAINSAW dies BOGS when throttling -12 Reasons Why!
An Enlightening Explanation of Diaphragm & Gasket Fitting positioning FOR GREATER KNOWLEDGE
A chainsaw can stall or die when throttled due to various issues. Here are the common reasons why this might occur:
Air-Fuel Mixture: An incorrect air-fuel mixture can lead to stalling. If the mixture is too lean (more air, less fuel) or too rich (more fuel, less air), it can affect engine operation.
Clogged Air Filter: A dirty or clogged air filter restricts the airflow to the engine, resulting in inadequate combustion and stalling.
Fuel Filter Issues: A clogged or dirty fuel filter can limit the flow of fuel to the carburetor, causing power loss and stalling.
Spark Plug Problems: A fouled or worn-out spark plug can lead to poor ignition, misfires, and engine stall.
Fuel Quality: Stale or contaminated fuel can cause starting and running problems, including stalling.
Carburetor Troubles: Issues with the carburetor, such as a malfunctioning float, stuck needle valve, or clogged jets, can result in stalling when throttled.
Exhaust Blockage: A blocked exhaust, often due to carbon deposits or debris, can restrict the flow of exhaust gases and affect engine performance.
Ignition System Issues: Problems with the ignition coil, spark plug wire, or ignition module can disrupt the spark, causing the engine to stall.
Throttle Linkage Problems: Misadjusted or damaged throttle linkage can lead to poor throttle response and engine stall.
Compression Loss: A loss of compression due to issues like worn piston rings, damaged cylinder walls, or a blown head gasket can result in poor engine performance and stalling.
Vacuum Leaks: Leaks in the engine's vacuum system, like a cracked or disconnected vacuum hose, can disrupt the air-fuel mixture and lead to stalling.
Idle Adjustment: Incorrect idle speed settings can cause stalling when transitioning from idle to throttle.
Overheating: Engine overheating, often due to a lack of proper cooling or air circulation, can lead to damage and stalling.
Dirty or Worn Carburetor Parts: Accumulated dirt or wear in carburetor components like diaphragms, jets, or gaskets can affect fuel delivery and engine performance.
Muffler Problems: A damaged or malfunctioning muffler can lead to restricted exhaust flow and poor engine operation.
Fuel Line Issues: Cracked or deteriorated fuel lines can result in fuel delivery problems, causing stalling.
Oil-to-Gas Ratio: Incorrect oil-to-gas ratio in the fuel mix for two-stroke chainsaws can affect combustion and result in stalling.
Intake Manifold Leaks: Leaks in the intake manifold gasket or boot can disrupt the air-fuel mixture, causing stalling.
Fuel Vent Issues: Problems with the fuel tank's venting system can create a vacuum in the tank, limiting fuel flow and causing stalling.
Inadequate Chain Lubrication: Chainsaw chain lubrication issues can lead to increased resistance and affect engine performance when cutting.
Identifying and addressing these issues is crucial for maintaining a chainsaw's performance, preventing stalling, and ensuring safe operation. Proper maintenance and troubleshooting are essential for resolving these problems.
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!

I am a visual learner. This is amazing. This is so easy to understand. This was all like a kindergartner attempting calculus for me. It seems so simple now. The problems, the solutions, the diagrams as a visual aid. Thanks for this 🙏🏼
you do a great job showing and teaching this !! you are about the only one on any subject that explans everything !! thank you for taking the time to help us all !!!
Thank you so much for your motivating comment, really do appreciate it. Thanks again
After having watched hundreds and hundreds of videos on similar subject matter I can't sing enough praises for yours. Granted it is a bit long but absolutely necessary to achieve the exceptional clarity you provide. Anyone who won't watch the whole thing doesn't deserve the knowledge you attempt to share. I'm a civil engineer and a professional instructor in several technical areas. At no time have I seen anyone with your ability to simplify and elucidate on such a major issue that has dozens of causes. I consider myself privileged to partake of your instruction. On the whole of my internet experience I have subscribed to only a few sites. I have learned as much on providing instruction as I have in content here. I shall add you to my very few favored providers of instruction. Thank you for your efforts in this regard. Sincerely, Kenneth E. Weldon, PE>
Wow. If ever I had positive feedback then this is the day I had it. Thank you so much for taking the time to leave this feedback, it keeps me motivated to continue. Many thanks again. Craig
Excellent in depth educational informational video. Thankyou, appreciated from Australia. 👌
Hi.
Thank you.
This is one of the most comprehensive, easily understood tutorials on 2 stroke engines I have every seen. I am no expert but this raises my awareness of the beauty of engineering and the methodical approach to solving issues. Thank you for the time you have invested in this. Regards Willie
I found a mounting strut loose on a Briggs & Stratton single cylinder. Tightened the stud, and fixed the air leak. Thanks for the tutorial. Well worth the watch.
Thank you so much for the nice feedback. I really appreciate it. Craig
I have a zenoha 26cc. When engine goes to full throttle it drops to half power. Any ideas
Understanding the concepts and principles of operation is probably ten times better for me than all of the "how-to" videos I've come across so far. I've already gone through the carburetor five times, and even replaced the two diaphragms, after this video, I went through it once more, for all of the little things I neglected to check, and decided the problem wasn't there. The Stihl MS 310 isn't quite the same as this, but the principles are the same. I made it my plan, to go through this list, one item at a time, and the most likely culprits first. The next most likely seemed to be the fuel line, and although it looked fine, a little bit of air pressure revealed it to be broken. Problem solved! In a matter of about one hour, a problem I've been chasing for two weeks, now (about six years, of you count the time it's been sitting because of this problem). This will help in my neighborhood, after the destruction wrought on us, here in Florida, by Hurricane Matthew. Thanks for this brilliant and comprehensive video.
Robert Mertens I have a Stihl MS 210c chainsaw and found it's problem to be a cracked "dry-rotted" fuel line with a tiny hole in it. I suspected that was the problem for a good while but couldn't confirm it til I just happened to have the air filter cover off and noticed fuel spraying out of the fuel line.
Whatever the case may be, my friend...stay inquisitive and always do your research. UA-cam is a TREMENDOUS tool for learning. Use UA-cam for all it's worth!!
Lawnmower shops don't want to deal w/these lil 2 stroke engines. They all use Zaymmer Carb's almost. I just learned tonight about the "SPARK ARRESTOR" that completely cloggs up & cause the engine to idel but not run i.e. no where for the burned fuel to get out cause bog down. I've never seen a lawnmower man speak of that. But I would bet a dollar thats whats wrong w/my Ryobi I bought a new Carb for my Pouland after trying 2 battery powered trimmers one only had one line 20v Lithium so I tried a 40v two line trimmer it was DOA batteries wouldn't charge. So I knew there be someone like this gentleman that covers this on a school level instruction very good resource for sure.
Watchman4u If you're having problems with your spark arrestor clogging up, you may be putting too much oil in the gas. If the tool in question is a Stihl chainsaw, then it probably wants 50:1. Too much oil can cause other problems with carbon buildup. My old Ryobi trimmer called for 32:1 and it stopped running because the ring got stuck in its groove and it lost compression. The truth is that you never need any more than 50:1 but the carburetor will have to be adjusted to use that ratio properly. Adding more oil to the gas will lean out the air/fuel mixture while decreasing the oil will richen the mixture. If your carb requires a special tool to adjust the screws, just cut a groove in them with a hacksaw. Be careful to not cut too deep. You can find detailed instructions on how to tune a 2 cycle carb on the internet too. I hope this helps.
I'm from Puerto Rico and your English is so clear and easy to understand. You never know how much you had helped me. I had seen lot of your videos. God bless you a lot. Thanks.
This video without doubt contains the know-how of an expert and it is also fantastically well put together. Thanks.
Wow. Thank you so much for your very positive feedback. I really do appreciate it. Many thanks indeed!
This is one of the best, if not the best how to video I have every seen. I am sure it took alot of time to create and that it is free to the viewer is a real blessing. One question, if your barrel seal or crankcase seal is leaking, would you see any oil or fuel residue? Thank you for your effort and congratulations for the quality of this video.
Why don't we use the concept of carburettor to make a fine taste orange juice mixer straight to our mouth? Just a joke. The 'breather hole' is a key word. The another key word, 'fuel starvation'. Thanks for the detail explaination.
I just bought a brand new ryobi backpack blower and homelite weedwacker and they both bog down...very frustrating ☹️😡😤
thanks so much, I recently rebuilt my poulan saw carb and am having trouble. It dies when releasing the gas and takes constant on/off throttle engagement to keep it going, after a minute or two it goes full throttle without any bogging down. I'm adjusting the l and h screw and hope that'll solve my problems. Thanks again!
Bill Dauterive, brilliant, I hope you can sort it very soon. It sounds like it's lean of fuel and you are right to try the L and H screws first. Good luck 👍
No just clean your spark arrester. Remove the screen from your muffler cinch it in a vise. Get a propane torch and heat the spark arrester screen till its red hot and wire brush the burnt carbon off. And reinstall. It should start up and run well.
Great video best I've ever seen just curious do you have any videos on natural gas systems specifically a two cylinder generac whole house generator.Or any general information.
Barry Drake hi, thank you for your post, leave it with me and I will see if I can supply some information. Thanks again, Craig
I have one more reason for a bogging and slow revving two stroke. Stuck piston ring!
The symptom is caused because the crankcase pressure/vacuum pulsation will be weakened when the air leaks past the piston ring on both up and down stroke. This will weaken the engine performance slightly but more important cause fuel starvation at full throttle speed. An engine in this condition will most certainly bind from the lean condition if not fixed immediately and that will cause damage that ain't worth repairing even for the DIY guy.
Btw. If you found this to be a useful tip please click the thumbs up. I have experienced this with 3 different weed wackers so i bet it is a fairly common problem.
Formula400Pontiac, yes I agree. There are many causes
of bog down, much more than what I have listed. The ones i included are just my experience of some of the most popular ones . Thanks
What a superb teacher you are ! Thank you for taking the time and effort !!
By the time I watched 2 or three out of 12 all seemed elementary My question has to do with spark & ignition. Will a weak coil cause failing of steady acceleration or even no acceleration from idle state. ???j
As a plant engineer for 35 year thank you from everyone .
Many thanks for spending the time to put this video together. After watching it i now feel confident in servicing my Weber Carb with new diaphragm and gaskets and re-setting the high and low needles in my 2 stroke aero engine. Thankyou!!
Dear Sir,I don't know how much thanks to say in here to you. But after I watched this video that I understand completely the concept of the carburetor in a small engine. Also I had a Echo back pack blower that was given me a hard time to start. The problem was found in the metering diaphragm. Replaced new diaphragm and I'm back to the business. Thanks so much for your time to explained and work thru every single steps. Please keep posting. You were a big helped a lot of us out here.Regards, Mino Haong
My carb doesn't even have a mixture screw. Damn it!
Hi. I love the videos, but I have one question about this one. I was under the impression that the gas cap needs to provide a tight seal at all times, and the "breathing" by the tank was facilitated through the return line coming from the primer bulb. Am I missing something? It this carb different from the 2-cycle carbs that I'm accustomed to? Thanks.
I think you're right for many engines
Fantastic explanation and model. I just always wonder why it's called a metering diaphragm and metering needle when it seems like it's really the low speed and high speed needles that are doing the metering.
Lotta time into these drawings! Appreciate the attention to detail!
Out of all the mechanical (car, power tool, moto) videos I've seen these are by far the best. Really great carb explanation. I've struggled with tuning/repairing carbs but at least now I have a much better understanding. Thank you for the time and information.
Good video bit i might add that restricted exhaust due to carbon build up in a muffer, exhaust ports or a restricted screen in the out let of the muffler can act pretty much the same way
Thank you for sharing your knowledge, I never own a weed cutter before but after 1/2 a day of usage it bogg down. after watching your video, I was able to get it working again....
MANY THX...
very well spend hr to lern something very important when you own a 2cycle engine, thx a lot
Absolutely excellent tutorial. Very easy to understand, now all I've got to do is work out why my saw idles, accelerates a bit, bogs down then picks up to full power. I'm thinking I've got a bit of dirt somewhere. Thankyou for explaining so comprehensively but in layman's terms.
Awesome Video. You answered so many of my questions that I have had for so many years. Thanks so Much
Excellent! The stiff diaphragm valve gave me an "ah-ha" moment for a strimmer I have. Great video, thanks for taking the time to put it together.
Excellent Excellent Excellent explanation !!!!! By far absolutely the best display and explanation on UA-cam for 2 stroke Carburetor discussions.
You by far should be quite proud of your work and generosity to share knowledge.
Well done SIR - THEREPAIRSPECIALIST - Thank YOU THANK YOU.
You have taken an amateur with serious curiosity & desire - and have made me closer to a professional.
I commented on one of your early videos with recommendation to include the diaphragm understanding for/with the H & L adjustments.
You have outdone yourself and everyone on YouTude with an absolutely brilliant outstanding solid understandable discussion/illustration/display.
Me Hat is off to you - THANK YOU TO THEREPAIRSPECIALIST
If there were more people like you in this world - it would be a wonderful place for all to grow peacefully enjoy.
Thank YOU - ALAN
Great video The only thing I would add to the discussion is primer bulbs can crack and cause an air leak and bogging. Eventually difficult cold starting as well from a bad primer bulb
Hello, I have a trimmer with single bolt carburetor and it doesn't work with choke off. With choke on it runs perfectly even warm in all speeds. Trimmer is new (cheap) and I suspect that mixture is too lean. Any suggestions what and how should I try to adjust?
Hi. I actually already have a video here on youtube that may help with your issue. You can find it here: ua-cam.com/video/yabdpL3aqiI/v-deo.html . Thanks
this is excellent. hope you dont mind but ive been showing your vids to students.
Thanks for taking the time to put these together.
Me too :-)
Great video. The carburetor remains a mystery to many people who own small engines. Thanks for taking the time to be so thorough and patient during your explaining it all.
Hands down the best explanation on the internet ever. Believe me I've been through lots trying to get my equipment working properly. You're mention of the tightness of the long bolt and screws holding everything together preventing air leaks is gold . I overlooked that focusing on the obvious. Excellent work sir. many thanks from sunny California
This.
Hi these Videos are great
dont forget about blocked exhaust ,,this will make your engine bog and power loss Cheers!
Thank you for taking time in making this video, very useful keep up the great work. God bless. 🙏🕉
You are very welcome. I appreciate your comment and contribution. Craig 👍
I’ve had issues with air lock on my zero turn, due to fuel cap not venting. Actually took the cap off one side and swapped with the other side, to diagnose it. Took the cap apart and the check valve inside was fine. Cleaned the cap, and didn’t have another issue.
Fantastic! Thanks for sharing. Craig
Low is adjusted for quick trigger response, and the high is adjusted for high speed power. I always adjusted the high to rev at its highest speed, and then opened it slighty more, to provide extra lubrication into the engine, but not so much to lose power. This prolonged the life of the engine. ( I fell timber, in my younger days, and always re-kitted my own equipment carborators.)
Awesome thank you for linking this video for me. I appreciate you sir. Thank you for sharing your skills knowledge and experience
Thank again for your great feedback. Craig
Good video. Just to note, the Lo speed screw is longer in length compared to Hi speed. Very helpful. Do you have a link to the 2nd video you mentioned? Thanks.
IF WE/I ONLY HAD TEACHERS TO LIKE YOU SIR, WHEN GROWING UP IN THE SLUMS OF AMERICA DURING THE SIXTIES....JUST TO THINK !!!
Thank you for your great feedback. Craig
Wow impressive. The most comprehensive video in the subject in all internet. ¡gracias por compartir!
Thank you very much for your nice feedback. I really appreciate it. Craig 👍
I've started lots of cars with 20 year old fuel

matthew griffiths, wow, thank you so much for your motivating comment
I’ve put up with my saw bogging down for over a year had it
to the experts and no better watched this video and now it runs as sweet as a
new one thank you
red stag, brilliant, I'm really pleased it helped. Thank you for letting me know. 😊👍
Great video. Very informative and very well presented. Thanks for sharing your wealth of knowledge. 👌
You did not stress enough one of the most common problems of fuel lines from tank to carb. These lines become hardened and brittle and develop cracks or become loose at the point of the fuel line connection point. It is one of the most common problems.
Mainly because of modern forecourt petrol and the check valve damage it causes, as well...
It's fatal to carb type fuel systems.
I've spent a few days now, ordering, buying and fitting (all were necessary parts) - purge bulb, fuel lines, gaskets, full Walbro carb repair kit, in-tank filter, doing carb cleaning, tank cleaning, fuel cap relief valve...
And it still won't run more than a minute or so.
Turns out the check valve seat was corroded, thus preventing correct fuel uptake, and this is non repairable. (Although I am going to try grinding off the damage - nothing to lose, now).
Now I only use Aspen alkylate premix, it lasts years too.
Knowing what I know now, would've bought a new carb straight off.
Awful stuff, this modern petrol.
I'm new to small engines,got it,thank you.
It is abundantly clear to me that you spent considerable time creating and assembling this very thorough presentation. I appreciate you very much sir. Thank you for sharing your skills knowledge and experience
Wow. That was some amazing feedback. Thank you. I really appreciate it. Craig
Hi i am from Brazil and found it very interesting this video, I live on a small farm and use a lot of mowing. Right now my mowing does not have acceleration and became very clear to me how the carburetor works.
Thank you very much for this video. This helps one know how the different components work together. I will be watching your other videos.
Excellent explanations and illustrations. A great overall educational video. Well done!
my engine bogs with a rapid throttle then it runs fine. only under a load.
Open your low jet a 1/4- 1/2turn and try it. I have a small engine shop and run into that a lot.
IAM A PARAMOTOR PILOT AND IAM HAVING ISSUES WITH ROUGH RNNING OF MY PARAMOTOR. WATCHING THIS VIDEO HAS HELPED. ALOT.AND ILL BE CHECKING EVERYTHING OUT THIS WEEKEND.THANK YOU. ;0) PARTS BROUGHT FROM UKPPG KNOWLEDGE IS ALL I SEEK
it was the cap! Many thanks.
thanks
I suddenly feel confident about my relationship with my chainsaw :)
My tired brain lacks the words to express how helpful this video is, right now, but still.
The clarity of explanation..... the quality of illustration....
You, Sir, are a god damned hero of the garage tinker/diy-repair/lay person world. I take my hat off and bow to the effort you took and your awe inspiring success at this task you took upon yourself.
Excellent video, well presented. Thank you
I'm impressed by your video explanations. I've watched several and appreciate your thorough presentations when compared with others on UA-cam. I'm still confused about exactly how the throttle fits into the process. I've managed to get my Husqvarna 128ld to finally idle without choke or half -choke, but as soon as I try throttle to achieve a working RPM, it bogs and dies. I've tried to logic things out based on your explanations, but no dice. I can't absolutely identify what you're calling a "tick-over screw". Is that perhaps a British pronunciation difference versus Texan/US term? Husqvarna has an odd, fine-threaded screw with a tapered point that I can't identify its function.
After watching your video listing reasons for blogging down, I've eliminated most causes as the carb, spark plug, fuel line and fuel filter are all brand new. Now that it idles without choke I'm confident that fuel itself isn't the culprit. I know you don't usually get into brand specifics, but what do I do at this point? Also, I'm not quite sure how to look for your reply, but in any case, I appreciate your videos. We'll done!

Say, maybe you could do one on why a 2 stroke engine all of a sudden starts smoking like crazy.
Your video has been the best I’ve seen explaining how a two stroke engine works! Thank you for passing your knowledge!
am mower mechanic i want to lean more on line
I have an Old 2 stroke Mantis. The manual is useless. Watching your video is like manna from heaven; wonderfully explained. I wish that I could buy you a pint!
Thank you man, you saved me 200 Euro, my brushcutter was bogging down all the time, and I was about to spend 200 Euro on a new one, then I saw this video, guess what?, the petrol was 6 months old, bought petrol today, problem solved
Samy Nasr. Brilliant, I'm really pleased to hear. Thank you for your positive feedback
Excellent - Yet another reason why I just have a new carburettor fitted !
Thank you for great educational material, beautifully explained through simple diagrams. I'll be looking at your other videos.
Best engine troubleshooting video i've seen so far. Thanks a lot sir
Thanks for the very helpful video.
I failed to notice it was over an hour long, which was just as well as I may have missed what was so helpful!
I was inspired to fix a poorly pole chainsaw. Now works sweetly.
I was cleaning my father's mower carb when a child but never had a clue what was happening... Now 50 years later it is clearer.
Then fixed an electric mower, electric scarifier and finally my troublesome old Honda powered 4 stroke mower. Using some of your principles, and others ideas.
Then cut the grass!
Other folks comments cause no little levity and so glad you were polite even with some provocation.
Thanks again for your efforts. Keep up the good work.
Fuel tank cap was my issue, thanks
Thank-You very much for your great 'detailed' video & your time.
Ya man I subscribed on ALL my channels and I'm going to blast this channel in a VERY GOOD WAY in as many videos as I think of. JUST AMAZING REPAIR SPECIALISTS everyone needs to land this so saws and trinkets so getting blown up
Wow what a video! The small engine genius! Thank you Sir! So GENEROUS of you!
mbibace, thank you so much for your amazing feedback. I
really do appreciate it
Amazing video!!!
Thank you for your nice feedback. I really appreciate it. Craig 👍
Thanks TheRepairSpecialist. I have a stihl FS220 trimmer and MS170 chainsaw which I've learned to use but never managed to sort out the problems when the machines cannot start or get bogged down. This video provides a step by step overview of what to look for if the engine bogs down and I am going to make use of the knowledge -- thanks very much. Would you also have a video if the engine doesn't want to start? Imagine and this is merely a "crash course" haha....thumbs UP!!!
Fantastic! thank you for your positive feedback. I will look into your request on the vid as well. I'm a little busy at the moment with another projects and will see if i can produce something after. I really appreciate your feedback.
A professor! This should be on a CD and used in all small engine tech schools. A fantastic visual and clear explanations and descriptions.
Derek Charette your a prick
Hi I have a question.so I set my screws at 1 turn.on my H I had to turn clockwise for more rpm.why do I have to turn counter clockwise to restrict such high rpm.wont it damage engine?
No, higher idle as a result of a lean condition will not maximize optimal power curve and will ultimately cause deprivation of lubrication
Hi Craig
Thanks for the video by far the best on two stroke bogging down problems on the net great animation
cheers Shaun
shaun craggs
Great video indeed. Thank you very much.
Thank you for taking the time to give me positive feedback. I really do appreciate it, and it helps keep me motivated to continue making these videos. Thanks again, Craig.
Truly best teaching. Thanks a lot !!!
Thank you so much. I really appreciate it. Craig 👍
Great video
thank you for your positive feedback. I really do appreciate it.
TheRepairSpecialist .
great vid explained so that anyone can understand thank you sir
Great video, thank you .
Good video but two things you should have mentioned are that some carburetors use floats instead of diaphragms and that old fuel can also gum up the orifices inside. This is especially true if the fuel is left to sit inside the carburetor between use. The engine should always be run out of fuel before storage. Even if just a few weeks. Lastly, it is a good idea to periodically remove the high and low speed screws and fuel line then spray carb cleaner into the carburetor to dissolve any gum that might be building up.
Roy Riederer, thank you for your valued feedback. Your points of course are both extremely true and valid. I didn't add them points to this particular vid because I had a plan to add them to another vid dedicated to this important subject. I do have it on my agenda to include all of this info in detail. Thanks again
Its a good practice to remove the carb before cleaning to avoid damaging the engine.
Hate to be back watching this vid again, but so thankful it exists. Love TheRepairSpecialist channel!!!
Well TY. First off I guess I never understood a 2cyl. carb & it's workings. I also didn't know how it took in fuel. You made me feel like a dummy, but the education will save me a lot in tools. Since every time I can't figure something out. I throw whatever is in my hands.. hahahhaa.. I can not thank you enough..Kudos dude... :o)>
Al Iasm, thank you for your positive feedback.
Thank you, helped me fix my weed wacker
This video should go viral. Good info.
Thank you for your kind words
Great teaching, thanks so much! Have to understand how a machine is supposed to work before we can diagnose it.
Roberto Santiago Rodriguez. Brilliant I’m pleased it was of use to you. Thank you for your comment 😃
