Chainsaw Won't Start - What To Look For & How To Fix - (Husqvarna Carburetor Cleaning)

- Diagnosing and Fixing a Chainsaw that will not start.
In this video I will walk you thru the step by step process you would take to diagnose why your chainsaw will not start so you can repair the problem. This particular chain saw was taken to a small engine repair shop and the mechanic was unable to get it running. I told him I would look at it for him and see if I could find something he may have missed. I was able to get this chainsaw running. You will see the steps I took to check what the problem could have been and how I fixed it. I returned it to him so he could sharpen the chain and install the brake (which he kept at his shop).
You will also learn how to diagnose, disassemble, clean and reassemble a 2 cycle engine carburetor. This is the most common reason 2-stroke engines stop running (especially ones that are not frequently used). You would use this same process in rebuilding your carburetor... just replace the parts shown in this video that come in the kit for your carburetor. Many homeowners throw good equipment away because of a clogged carburetor when it is a fairly simple fix.
Today's fuel quality is poor and if left in the carburetor over a period of time it will eventually clog the small ports in the 2 cycle carburetor.
Go with me through this step by step carburetor cleaning process and you will be on your way to using your weed trimmer, blower, hedge trimmer, chainsaw and other equipment, in not time!

I took the same saw to a repair shop a few years ago and they told me that I needed a new carb, $85 bucks later I was good for a while. But I didn't realize that the alcohol in gas will turn to varnish if you don't use it up. I am determined to fix this problem this time, as I also did with my lawn mower twice. Now I buy gas with no alcohol in it. Excellent video, Thanks
Straight to the point and no BS. Thank you!
Just a tip....While you have the carb apart, hold the diaphragm up to a bright light and see if it has a hole or a crack in it.
make sure it clicks too
Clear step-by-step troubleshooting and maintenance techniques. Excellent.
Many thanks!
Dump old gas and replace with fresh. Add a little Seafoam engine treatment to the fresh gas+oil, cycle primer bulb 5 times, pull cord 5 times with choke on, then let sit for 24 hrs and soak. Next day try to start again. Fixes itself 8/10 times in my experience if the diaphragm and fuel lines are good with no saw breakdown.
THANK YOU ❤
Ya it happened with me but after one start and one use when i turn switch off I won’t turn on i don’t know what’s problem
doesnt have a primer bulb
Purge bulb.....they don't have primers cuz they have a choke.
Wow straight forward instructions. You gave me the confidence to open mine up and get it running I have never committed myself to fix a small engine before.
Respectfully Sack
Glad to hear that! You can do it!
Simply super lesson for me. 30 year old Husky 51 with the same problem
Glad it helped!
266se runs great. but when i run it to long starting runing away on me. have to shut her down
I like your style of describing every step of your way on the projects. 👍🏻🇺🇸🇺🇸🇺🇸. Thank You.
Glad you like them!
What a delight to see a smoothly explained theory, tear-down, diagnosis, and rebuild. This is an excellent video beyond just showing how to repair because the instructor is clear to describe what he's doing along with suggestions. Thanks
When you're done playing, replace the diaphragm. It's ALWAYS the diaphragm. Change the diaphragm once a year regardless If you use the saw or not. The part cost less than $1.
Except for the starting fluid
Just sent the link and asked my grandson to follow it to get my chainsaw to fie again. Very clear instructions - thanks.
hope it helps and inspires him to get it fixed
Well done. I might try this on a gas string trimmer
You Sir are definitely a Master at your craft.
thanks...
Thank you very much now I can get out that polan saw and replace fuel lines and clean the carb with confidence
Note i did not finish watching the video. To see what the carbs problem was.
But thought id mention a trick everyone can try as soon as one doesn't want to stay running or even doesn't run top notch.
My husky did it yesterday. First start of the season was a no go. Readjust and i was off and cutting.
My Stihl trimmer does it to me atleast twice a year or more.
All you gotta do is run the needles down gently seated and usually the setting is 1 and 1/4 turns out on both high and low needles. It should start then. Then adjust from there. Lots of videos on that.
But anywho. It must be trash or varnish builds under the needle and seat and running it in clears it. Its worked more then 30 or.40 times in my life. If you took it to a shop they will tear it down and sell you a rebuild job every time. Um very seldom needed. Not on old stuff anyway. Most of this new stuff you either cant adjust or need a special splined tool for the job. They cant sell you.
But i ordered a full set yesterday for my stepfathers polan and lord noes what else. New Junk.
Look for needles you can adjust. Or dont buy it. Or you can simple toss the carb and buy a new chinese one for around 15 bucks. Your call.
Note echo blower a couple years ago i bought new had no screws. Ran to rich, no power so i returned it i was so mad.
I heard from my local shop Most or them came tuned to lean and burnt up.
Check your local pawn shops for the older stuff while you can still get it. Then learn to work on it. Tons of videos!
It’s also a good idea to check the spark arrestor to make sure it hasn’t become gummed up. A little mineral spirits and gentle application of heat with a small propane/mapp torch will clean it right up.
Same experience. Once you learn how to adjust the high/low you’re good to go more often than not.
thew splined tools avail from wish china 5 bucks the set landed. Another tip is screw idle well in so enigne will run as u tune. ie low jet adjust till it starts responding freely then back idle screw off. especially handy if youve pull jets out for cleaning. i run the carbs thru a small ultrasonic cleaner its amazing the crap petrol leaves behind in the galleries of carbs.
Great video. It revealed many mysteries. It also confirmed my thankfully infrequent response to starting troubles ... take the bloody thing to a good small engine mechanic and let them sort it out. That might have taken you about 30 minutes. It would have taken me a couple of hours and I doubt that I could have put the thing back together again even if I figured out how to take it apart. Cheers mate.
Great video, I watched your carb cleaning portion and cleaned my carb, put back together, also cleaned my spark plug, adjusted the spark plug screws and running like a champ again, hadn’t used it in about two years, cut down a tree that was next to the house after finished it
Way to go... and if you don't use it much be sure to drain fuel out of gas tank and run it out of Carb and she should start right up when you are needing to use it.
Also doesn't hurt to pour a little 2 cycle oil in the fuel tank and pull the start cord to get a little in the carb to keep it nice while in storage.
My Husqvarna 240 lost spark so I replaced the coil and plug. It still didn't start and started dumping fuel out the exhaust. I installed a new carb, filter and lines and set the H & L screws out 1 1/2 turns. Now I have fuel and spark and it still won't start.
Just what I need to know, very happy to see that and learn about it.
My fairly new Echo CS 490 wouldn't start, or even fire when I shot ether into the carb. I'd about given up when my wife found this video. (I had watched several others, to no avail). I cleaned the carb., and now it starts and runs like a champ. THANK YOU for posting this!
You are welcome and Way to go!
Good info guys. This video is details how to service the chainsaw carburetor.
Thank you!!!! Thorough instructions! I love it :)
Glad it was helpful!
That was a big help. Thank you so very much
Very good instructional video.
Thankyou.
Glad it was helpful!
It took a bit of searching to find a video that took me where I was trying to get to. Thanks for the help. Speaking from experience, be careful about soaking up too much carb and brake cleaner through your hands.
Tyecad what did it do to you?
If I may, first see if has fuel and fuel lines are good with filters and then go through all these tips as well to ensure you have good working equipment.
Good job...
Love your teaching
I have a makita saw that’s hard to start.same principle applies here. Thanks for the video
Well done and you have it explained exactly , thanks!

Very good buddy 👍😊👍 Thanks a lot
Too the Point, well explained. Great good!
Glad it was helpful!
That right there was my Stihl HS45. I have one that works like a charm, then a newer one that wouldn’t start no matter what I replaced.
I succumbed and brought it to a small-engine repair place. He said it was a malformation in one of my gaskets.
I’ll let you know if that truly solves the issue.
This video is very helpful for process in the event I may need it.
Thank you.
Sometimes something like that can be tricky to discover
"Helping you online" helped me on line so now I can try something off line. I have exactly the same issue with a Ryobi. If I get it going I'll shout back. Ta ever so!
Let us know how it goes and what was wrong and how you fixed it. You can do it!
Brilliant information put across so well, I have same issue, when opening up the carb to check diaphragms one was wet so reckon it was punctured, looking for a replacement right now?
Great Job!!
My experience also is the stone filters break down & causes the grit you see in the carburetor. Switch to a paper filter & this will prevent the trash in the carb. My number 1 tip to all.
Great Video, have a Rancher 450 that probably has same problem, hasn't been run in a couple years and assume it's all gummed up.
It doesn't take much to clog those tiny ports on those carburetors. In the future... if you drain the fuel and run it out of the carb before you store it for a month or longer you will save yourself from having to do this. Thanks for watching

Great Job and video!
Thanks!
I have a Husqvarna Rancher 455 sitting on storage for about 10 years. I have not tried to start but I´m sure it won´t . I do not have your skills to do this procedure and will have to replace the carburetor (Amazon $27) if it needs maintenance. Thanks for the nice class.
Very good video ..in detail
Glad it was helpful!
Great job
Very nice work
You made it. That's great.
Thank you so much for the video. It is fantastic! I have a chainsaw that's doing the same thing. I will try this and see if that works. It has only run 1 time then stop working! Thanks again for a great video!
Thanks for your feedback.
You can do it!... and always remember to empty the fuel out of the tank and run it out of the carburetor if you are not going to use it for a while... will save lots of headaches...
i have H 240 also. Never use ethanol gas and if it wont start open the gas cap then retighten. This Chainsaw design gets vapor locked easily.
Very good video…..thx

When you spray starting fluid in the carb you need to hold the throttle wide open so the fluid goes to the cylinder

No problem 👍

Glad to hear that
THANKSGIVING
Breaker points on this was burnt up! Just replaced then worked!
Hi Folks, don't forget to add gas stabilizer when storing your machine, it is often the source of problems. Also use the best gas you can find, you'll be glad you did. Those small engines are fairly simple to fix, just practice preventive mechanical measures and you will avoid most common issues.
Most 2 stroke oils have stabilizers in them already! At least the higher grade ones do
DO NOT store gas in any machine over winter! Run it dry, buy fresh non-ethanol gas when ready to use again-
Totall TRUTH. I’d rather do a little preventative action that not and deal with an issue that didn’t need to become a problem.
I make this same mistake almost every year, I plan on taking it out one last time before the snow falls but never get to it. Come spring I curse myself every time. For years, before I knew this truth, I had to take my saw in for repair every spring. "The definition of insanity is doing the same thing over and over again and expecting a different result."
Husqvarna gas has Stabilizer in it by default & can sit for up to 2 years without issue. Cost more but you can relax when stored during winter.
If i could give it two thumbs up I would. Thanks. Shame the carb is so difficult to get to.
Glad it helped
You should consider buying a carb. They are often cheaper than a rebuild kit. It was the case for my Husqvarna 445e.
No need to buy a carb or gasket set
Very seldom will need to need to replace a gasket
Even if you tear one and it’s all still there it will still seal ok
I’ve even made gaskets from cardboard boxes when working really old engines
Just make sure the keys are cleared all you need is cleaner of any band
Acid brush
A wire small enought to crear the jet
Shop towels to dry the cleaning Fluid
I replace the diaphragm as well as the small screen in the carb every year, as well as the fuel lines and starter cord. Time spent now prevents down times when the machine is needed.
Nice video I always put fresh gas.
Love your video keep up the good work. I just got a old chainsaw from somebody I'm going to see if I can get this one running. I gave you a thumbs up 👍🐟💯👋👋👋👋👋👋👋😁😁😁😁😁😁😁😁😁
Thanks 👍
Good job
Thanks
Good video looks like the culprit is clogging of the fuel in the carb
Thanks.
One thing you missed was to check and see if the fuel filter inside the tank was intact or letting junk go straight to the carb and plug the needle valve. That may have been the root cause of the plugged carb to start with and it will happen again soon if the fuel filter is missing.
bad oil is mostly the problem as it jells up
Will it be the same or similar process on an autotune carborator
Funny I have a home lite xl and a home lite super 2. Got the xL to run first pull yet the super 2 for some reason when you pull it if it does start it runs extremely high rpm smokes out the muffler then kills. After dying it will leak fuel out of the exhaust and sometimes make a slurping sound as if it’s trying to suck the fuel through an extremely small straw w a vacuum. Iv put a little sea foam in there adjusted my carburetor screws of course. Will try it again here shortly
Excellent
Thanks
