By far the best video on the internet for working on the 125B! Sadly it didn't fix my blower and it's now at a service shop down the road, but was great detail nonetheless.
Great video image quality! Thorough and logically sequenced instructions. Every possible pitfall anticipated and explained. Clear, non-jivey English! Thanks to emilybritton (below) for the lube suggestion ... a touch of petrolatum or silicone lube should work fine. My Husqvarna dealer has ordered the necessary carb and I will post again with the outcome. 2.5 acre yard in metro Atlanta ... arrgh!
I used to do the break down, ultrasonic cleaner, etc. Couple of hours spent on it. The carb kits today have all new stuff. New fuel lines too, where a lot of issues start with the cheap chicom fuel lines today that crack/suck air/leak. It is not cost effective to break down/soak/clean. Some even include the spline screwdriver to adjust the lo/hi settings.
One thing I learned real fast with yard gas power tools is NEVER use pump gas - the alcohol destroys the plastic. Best is bite the bullet and buy premixed fuel. Worth the cost. Super vid, BTW.
Yes, I agree. We have a non ethanol gas station here. Just about ten cents higher than ethanol laced gas and cash only. I have decided to go there from now on.
Thank you for this video. My sister-in-law had a landscaper leave a Husqvarna 125BV in her yard and it sat outside for two years and she had it in her garage for another three or four years. After seeing your video I bought a carb kit and replaced the carb. My first small engine repair. It runs like a charm.
Thank you for taking the time to leave such a nice comment. May I warn you that the cheap hoses may only last for a couple of seasons. I recommend the brand 'Tygon Tubing' that brand is used in industry.
That is the best video i have seen on the 125B model. I was only looking for a video on replacing the gas lines and it was clearer and explained better than ANY video I've seen. BTW you should add gas line replacement to your title, I bet it will get a ton more views. Thanks! Awsome video
Thank you very much for taking the time to leave such a nice comment and an excellent suggestion. I have found Weed Eaters to be the worst when it comes to a broken fuel line messing up the operation. Thank you again.
thanks for the video, this tutorial gave me the confidence to try the repair myself and I killed it in like 20 minutes with no problems. my blower is running stronger than ever now!
I watch a lot of you tube DIY vids, and this truly was one of the best step by step tutorials I’ve watched. Followed exactly and fixed my blower in no time. Amazon has the whole kit to include spark plug for less then $20. Again, thanks!
Hi. Great interactive video here. Yes, it does make a diff. Which side you connect at the bulb. One side sucks and then other begins to push. It is called priming the carb. Sending gas to the carb at the lower connection closest to choke lever. If you hook it up backward the bulb will not come back out if you press it in. In fact, I just had mine apart and it is the shorter connection on the bulb that goes to the top of carb which sucks gas into and through the carb. Thanks for mentioning this. Most people do not know which one side is which. Thanks for your video.
First off I LOVED your presentation and was literally in the process of buying everything to repair my 'never ever start' blower, when I ran across a comment from someone that said that the only thing wrong with their Husqvarna 125B was the vented gas cap was clogged (creating a vacuum in the tank) which prevented it from starting... Well 1/2 can of canned air later applied directly to the little hole on top of the cap and she's running like a champ now!!! 😉😉😉
Thanks for taking the time to make this. I have the exact same blower, swapped out my carb tonight with the help of this video and it's back to running again.
Excellently explained, best video I've seen on this! I had a very difficult time feeding the line through the rubber gas tank grommet. I found it very helpful to put a small amt of lubricant on the line. It slipped right through and made world of difference!
After being quoted around $82 to replace a carburetor with a $35 non-refundable deposit on my blower (still in warranty, but they don't warranty fuel related issues) I wish I had watched this before I even brought it down for repair (so much for warranty work). I already HAD a replacement carburetor that I bought when I bought the blower (I like to be prepared, but since it was still in warranty.....). I really appreciate your video, it was detailed and explained extremely well, thank you. I'll give it a shot this week.
@@A_Renaissance_Man Hi David, thanks for the reply and video. I picked up a cheapo blower while mine was in "limbo", so I've got that as a backup. I just have your video on my tablet, so I'll be using that in the garage when I do the carb install. I feel confident I'll be able to the install with your video there to guide me, plus I'll take pictures as I go as you had mentioned. Would this be close to changing a carburetor on a Husqvarna 128LD String Trimmer?
I used this video to investigate problems with my 125B and low and behold, the two screws you mentioned were loose, the ones that keep the air filter, carb from moving all over the place, I also had one broken engine mount and a broken mounting screw (different hole). I remember everything you said except the stupid blower fan nut. I turned it left to loosen versus right and damaged the nut threads. It looks like the threads on the shaft are usable, so I ordered another nut to replace. I hope it works. If I could get another season out of it, that would be great. Thank you for the great video.
David, thanks for taking the time to record, edit and post this. It is well done and very helpful. As another commentor mentioned, I just needed to replace the broken fuel lines but had run them to the wrong things, but I expect that your excellent video will guide me.

I was going to take my Husqvarna leaf blower into a service center to have it serviced but after watching your video I decided to try and do it myself. I ordered the new Husqvarna OEM carburetor from Amazon which cost $10 more than the generic brand but was worth it. Your video was so clear after watching it just once I tackled the job myself. There were a couple of instances where it turned out to be a bit more difficult to do than I thought it would be but I worked through it. All in all your video was very well done and gave me the confidence I could do it myself. Thanks for your effort in putting that out there for us DIYs. A five star video!
Your explanation and video was better than others I found. Thanks. I got the sons running again. I only needed more explanation on how the fuel lines were specifically replaced going into the fuel tank and the fuel pickup.
Thanks for the great video! I have the same leaf blower and had the same problem. I followed along with your instructions and it now runs like a champ! 🙏
Thanks...I have exactly the same problem with my 125B. It's 7 years old, so it gets a new carb and all the other parts you installed. Until this week...first use this year...it has worked flawlessly. So...it gets repaired. Great video.
Thanks for this video. I got way ahead of myself and disconnected the fuel lines without noting which lines attach to the upper and lower fuel line nipples. Naturally, I hooked that up in reverse order. Gaskets; I screwed that up too as it appears that the inner gasket should be sealing up vacuum alley. Needless to say, I have adjusted the fuel mixture on the high and low settings in and out. Close both and bring both out 2-1/2 turns as a starting point. A quarter turn to fine tune. However, I could be wrong. I can get the engine to start, but it leans out and dies. Miraculously, I did a head gasket job in a car last year, tuned r/c nitro engines for 30 years, but this, this has me so infuriated and on here. Thank you for this video to get my gaskets in order. I am sure dissembling for the third time is the charm 😜
I did this and it worked. My Husky 125b was sputtering all the time and dying until I replaced the carb. Like the author said, make sure the fuel lines don't get pinched behind the carburetor on re install. Got the OEM kit on Amazon and it worked fine. And PS, get the new fuel lines and primer bulb when you buy. Money well spent.
Great video, thanks. I got a little kit off amazon for $16...carb, spark plug, gaskets, bulb, extra filters and now running like new. Y'all may want to use the camera and take plenty of pics......like it says in the video.
Great video showing correct connection of gas line to each carburetor gas line connection point, in tank filter , primer bulb, and flow back gas line back to gas tank.
You have a most awesome video! I have a Craftsman blower which was made by Husqvarna- only difference it's yellow, not orange. Got a carb from Amazon for $14 and some change. The biggest pain? Realigning that dumb spark arrestor cover. Aside from that, your directions were precise, easy, and spot on. Thanks!
@@A_Renaissance_Man You're very welcome. Too bad some people throw away their 2 cycle yard machines when they stop running well. It's really an easy fix!
I opened your site, read a few reviews and downloaded the video to watch later. A few days later I opened the file and heard no sound. At almost 75 I get pissed easily. I said how could he get such rave reviews. Opened up your site and found out MY downloading sucks. And I agree the video was just great. And even better with sound. Must learn to calm down.
I was looking for a lightweight blower for my deck. ru-vid.comUgkxgioZQl3J5wPGAeDINzbieKbT5qomSEx3 There are some huge trees around my house and the leaves and pods drop all over my deck. Having to move furniture around to sweep has become too big a chore. This blower was the answer. It is light enough for this 70yr old lady and powerful enough to blow all the tree droppings off my rather large deck. Thank you B&D. Be aware the cord is not included. I use a 3 prong outdoor cord 25' cord for my 12' x 20' deck. The cord retainer works very well, but don't try to pass the plug through it. That is NOT how it works. You just have to loop the cord and it works great. One of my best purchases. Very happy.
Done - Blower works like it did when I bought it. Finally able to keep it running and actually run it full out. Before I couldn't go past the 2nd level if ya know what I mean. Again, thanks for the great video----my wife thinks I'm a mechanic now. LOL
For another $10-15 more you can get the genuine Husqvarna OEM carb on Amazon. It's worth every penny. Those sub $20 Chinesium carburetors are hit and miss...mostly miss. And then you have to adjust the daylights out of them and it's a constant battle every time you fire up your blower. The OEMs are mostly plug n play and they last.
Thanks David great one! I'm having trouble with the same blower but its the throttle trigger, it is stuck in high. In other words it won't pop back down to the return position, is there a spring or something on the carb that has failed or is it broken on the carb? Thanks if you have time to reply.
There's a plate on the carb (the one with the large two screws). Remove that plate, and in the dish with the hunk of debris, remove the debris, and clean it out with brake cleaner. Replace the "lid" and put the screws back in. Reinstall everything, and enjoy your "running like new" machine.
This video is a great help. Just one question on the bulb there are the two hose connections one is shorter one is longer which one goes to the carburetor and which one comes from the tank to the bulb?
Yea, I dodged that in the video. The short line on the Purge Bulb might be stamped 'in' if you can see the black-on-black writing. The long one is the out to the gas tank. The short one goes to the carburetor and the long Purge Bulb line goes to the fuel tank. You can test to make sure but remember this does not flood the carburetor, the Purge Bulb only removes air from the line.
Swapped out carb, fuel lines, plug and air filter. Ran great at first then after a while felt like it was losing power. Temperature was in the 40's when I did the test run not sure if thar has anything to do with it. Any ideas?
Mine just wore out. The rings were gone and the piston was scrubbing the cylinder walls. Of course the only to tell is by trying to look on the carburetor or muffler side to look for ware. Sounds like you might be experiencing the same thing.
Thank you! Excellent video. Does anybody know the risks of not having the grounding wire? I seem to have lost mine...will that prevent it from starting?
Aloha David- Thanks a bunch for sharing your knowledge and skills. Followed your video and was successful with my repair. The fuel lines on my blower were broken and seemed to be deteriorating/softening inside the fuel tank. Was wondering if that is due to the ethanol in the gas? Take Care & Be Safe!
Although that could contribute, the primary cause is age as the lines just become brittle over time. I have found that the location of line falure are typically at intersection where the line goes into the tank. I use high octane fuel as the chemical base is different from the lower grades. Also, ethanol free gas might also be available. Very high octane avation gas is also an option, but you should get four to six years out of a set of fuel lines no matter what fuel and oil combination you use.
Well ... Instead of a link, please search Amazon for Husqvarna 125B Leaf Blower Carburator and you will see 4 or 5 listings of the same model number. Amazingly, prices range from $12.99 to $30.99. Most are Prime if you have that. The one for $13.24 is the best but, the one for $18.99 also has two primers, two fuel filters, a spark plug, and a carb mix adustment screwdriver. Good Luck and thank you for trusting my response.
Great video David! I noticed that you said only buy Tygon tubing. What size! My 125b has 2 different sizes and it appears that you just used one size. What size do I need?
Looks like my go-to size is 3/16 OD x 3/32 ID. I recommend just measuring, a ruler is close enough. The OD is what is important. Only use Tygon 4040 otherwise you will replace them every other season.
@@A_Renaissance_Man thank David! I just bought that size and brand. I saw you used mostly a different size so it threw me off. That size is the same as another youtuber diagramed so that's the one I will use buddy. You have a subscriber 😊
I have the Husqvarna 125BVX ( same but with vacumn attachment) it is brand new, just got it, and it seems to be bogging down, losing power. Could it be the carburetor needs adjusting? Thanks
If you are lucky. Check out Steve's Small Engine Saloon on RU-vid for some good videos on making those adjustments. However, if it is brand new, take advantage of the warrenty. I know, that is a pain, but you can let the shop deal with it.
I haven't looked through the comments but on that primer bulb it does make a difference which lines hooked to which one by now you probably know that LOL
Actually it does make a difference. I did blow that detail off but, you need to make sure that the discharge goes back into the tank. The blub draws fuel out of the tank, through the carburetor, then into the bulb, and back into the tank.
I've been having issues with my 125B. I can get it to start but it runs for a few minutes before shutting off with no notice. Once it's off I can't get it started unless I wait 5 minutes or so. Any ideas? Carburetor so different?
Since you put a new carburetor on, could be the carburetor itself, mixed up fuel line placement to the carburetor or at the primer, loose carburetor attachment nuts, or misinstalled gasket. I have made plents of mistakes so I would pull it apart, look at everything and put it back together.
I have same model. I’ve had it for about 10 years. Never gave me s problem. Now though it will not idle. I’ve change fuel filter, air filter and spark plug. It will run and blow but I have to push the trigger. If I let go of the trigger it will idle for maybe 10 seconds and die. It will start back up but no idle. Suggestions??
Certainly sound like the Carburator needs to be replaced. The second suspect is a cracked or broken fuel line as they become very brittle over time. Good like in fixing your leaf blower.
Great video, thanks for explaining so clearly. Told today it will cost £140 to have mine professionally replaced, but having watched this I don't see why I can't replace it myself! Only thing I'm wondering - is there any real difference between OEM and cheaper parts on Amazon and risk of damage to machine, etc? Many thanks, James
Well James ... I have had pretty good luck with the cheap carburetors being sold on Amazon. Also, They only last two or three years so replacement is easier than repairing the hardened gaskets. May I highly recommend Tygon tubing and discourage you from using any tubing provided with the cheap carburetors. I also recommend using NGK spark plugs as they should last two or three years minimum. Another issue is that the piston cylinder will eventually wear out and then a replacement machine will have to be considered so why dump too many shillings into a machine that is wearing out with each use.
I ended up using the old grommet as the new one was definitely too large. When I replaced the carb and fuel lines on my Mantis tiller recently, I used a step drill and drilled out the hole in the tank to the diameter of the grommet.
