Thanks for watching. This Husqvarna trimmer wasn't starting and after taking a good look at it new fuel lines and a good carb cleaning were needed.
I found it much easier to just replace the carburetor for $13 on Amazon comes pre adjusted and more importantly, comes with flat head screws for adjustment instead of the ridiculous EPA mandated recessed screws that require a special Pac-Man wrench. Best advice after two seasons, throw out the carburetor throw out the fuel lines throughout the spark plug and make sure to properly mix the oil exactly according to the recommendations. Don’t forget to grease the trimmer head once in a while.
thanks
Thank you so much. Followed this video the whole way, replaced the fuel lines, cleaned carb, replaced filter that had come off from line. Runs as good as new. And I have never once done anything with a small engine.
Great to hear!
Awesome video! Many youtubers explain one part of the process, but you've shown top to bottom how to take it apart, put it back together, the post-op tuning process, and why you're doing what you're doing.
Hey thanks for the comment I appreciate it.
Brilliant! Had the exact same problem. Renewed carb parts but never in a thousand years suspected that the carb needed readjustment. Found this video by chance, followed it, and bingo. One of the best.
Thank you Steve O for the comment I appreciate it
Watching and hearing your explanation of adjusting the fuel mixture screws and idle screw was extremely helpful.
Hearing that you cleaned what needed to be cleaned but not seeing it was a bit frustrating.
Overall though, a great video and very useful!
Thanks for the time and energy spent sharing your knowledge.
Thank you for the comment I appreciate it. I'll try and do better next time.
This is my EXACT brand trimmer head.
I bought a battery-powered unit but I think I will give a repair of the old one a shot.
Thank you for taking the time to do this video!
no problem and thank you John Bedell.
Helpful. I havethe 126LD that's run flawlessly the 7-8 years I've had it, but I've never replaced the spark plug or fuel filter and this afternoon finally started to give me problems. This will help.
2 things I would've liked to know more about:
You say clean the carb "whatever needs to be cleaned". Carbs are more complicated than that implies. I would've liked to see exactly what and how.
I also would've liked some commentary as you were tuning it, not after. Also mentioning the tools you used to do it.
But all in all very helpful. Thanks!
You are absolutely correct. However they car so complicated that you cannot possibly clean every orifice. Can what looks dirty, clear what holes you can reach and see but after that doesn't work just replace it
It's very satisfying when you have diagnosed and fixed something
Oh you know it. That's why I started doing this channel.
Thank you. This video helped me replace the carb, fuel lines and fuel filter on the same Husqvarna.
Thank you for the comment I appreciate it
Great video explaining each step and even showing how to adjust the idle and adjust to how to keep it running properly. No issues changing my carburetor following your video
Excellent. Thank you for the comment
Thanks for the much-needed help! You nailed it from beginning to end as I'm getting more trimming done with your help.
no problem and thanks
This has helped me a great deal, from what I have learned from this video is that my problem is the diaphragm. Thanks
yes it is most likely the problem
Thank you for another video, Home Garage. What you showed seemed like a minimal rebuild. I usually use the whole kit because an aged needle doesn't necessarily seal consistently even after blasting everything out with carb spray.
You are correct. I very rarely use the full kit to rebuild carbs. If I find a carb that needs a full rebuild I usually buy a new carb.
Thank you. This video helped me replace my fuel lines. Parts were about $20. You saved me a hundred or more!!
Glad it helped
Wonfully narrated with detailed information, excellent videography and sound audio mix.
Most importantly, a practical solution in less than 10 mins (YaaaaY)
Awesome work man.
Keep em coming.
Thank you for the comment I appreciate it
Well done. Including the post-installment tuning process was very helpful as mine performed exactly the same way after replacing the carb. Thank you!
You are welcome and thank you for the comment I appreciate it
Very good and informative video. The slant cut of the gas lines was a great explanation. I watched other videos and they didn’t explain that or why. Good explanation of the tuning too. All very helpful and complete.
Thank you Tracy Roberts for the comment I appreciate it.
I just wanted to say thanks for making this video. Everything that you said and had show worked for me, and now my trimmer runs like the first day I bought it. Thanks so much again.
No problem and thanks for the comment I appreciate it
The explanation of the H and L and I screws makes things clearer.... we can hear and see the results and why you did them.
I appreciate your comment. Thanks
The old ones used a regular driver now you have to buy a special carb adjusting tool . Thanks so much designers !
Thanks, helped me out! Knowing that it was ethanol chewing up the fuel line was a helpful detail. Ethanol free from now on!
Thank you matthwy1 for the comment I appreciate it
Try switching to premium gas
@@samuelvelez1643 i agree
Great video! I had all these issues and followed you step by step. Not only that but followed your tuning and now it runs better than in the past 2 years. Will definitely be checking out more videos of yours when i need to do my small motor fixes. Thant and be way more diligent about maintenance. Thanks again
Thank you Brett Buller for the comment I really appreciate it
Great video very helpful it really helped to know the reason for turning each screw
Thank you Jacob Popielarczyk for the comment I appreciate it
I am pretty sure this trimmer uses the same engine as my 223L model. I am amazed with how much power this engine has. It probably gets up to 12000 RPMs at full throttle
I definitely agree with you.
Just had to do a fuel line replace on my husqvarna weed eater. This definitely helped. Thank you.
Thank you nick stevens for the comment I appreciate it.
Exactly what's wrong with mine. Ordered some new gas line, will fix when I get home from my hitch
Thank you Ryan Frentz for the comment I appreciate it
excellent video demo on how to trouble shoot and tune a husky trimmer. Thanks
Thank you Eugene Milton for the comment I appreciate it
Very good video-nice to see the damage ethanol does
Thank you Dan Carr for the comment I appreciate it
I got two of these things for free need these running before the spring lol. Thanks so much. I need a new fuel tank aswell
Glad to help
Man, thanks for this vid. Haven't started yet but when I do I'll look for this vid as a guide. Also, showed me a couple more things I didn't know before. Appreciate it.
no problem Marian Dillingham
Nearly 9 minutes of excellent advice! My rule of thumb is if you touch the carb touch the exhaust. Those pesky spark arrestors will throw you in a tizzy if you know what I mean. Happy New Year brother.
Thanks a lot for the advice it's a great idea. You too Dave.
That’s what I do to. I get rid of the spark arrestors there useless and only get clogged up to be cleaned over and over. Now I don’t have to worry about it anymore and my machines run much better without them
You put the plastic fitting on the wrong line. Per Husqvarna, it's meant to be a coupling for the filtered line, and pulled up snug against the inside of the tank.
Thanks for the information
Your video is the best one on this weed eater and I greatly appreciate it but PLEASE keep the beginners in mind when making these videos. We need to be able to see EVERY STEP CLEARLY. WE CANNOT ASSUME WHAT YOU ARE SAYING !
I did not see you connect the wires and I have no idea what screw you turned to get better gas flow.
Maybe a series of BEGINNER videos could be in your future !
I did learn a lot more from your video than any of the others on the husqvarna weed eater. Thank you
thanks for the advice
Thanks very much. You saved me from buying a replacement.
You're welcome and thank you for the comment I appreciate it
Another one saved from a future meltdown. Thanks and Blessings!
absolutely
when you show how you turn the screws it would be help full if you turn machine so we can see what you are turning
Thanks David Slick for the comment.
Thank you for this great video. I still have a question. In a couple of other videos, what is shown is that when the fuel line is inserted into the tank, it is pulled through he tank, and the white connector is inserted into it. Then a segment of the fuel line is attached to the fuel filter. And this segment is in turn inserted into the white connector. Then the fuel line is pulled until the white connector is set in place inside the tank, and the fuel line is finally inserted into the carburetor. This is what I believe I saw in a couple of videos.
In your video, I understand that you do not insert any connector in the fuel line. As I see, you insert the fuel line into the tank, you pull it from inside the tank, and then you insert directly this fuel line into the fuel filter. And then you insert the fuel line into into the carburetor. And then, it seems that you insert the white connector to the return line only. So I am afraid that I end up being confused, not by your video, but by the fact that there seems to be two different procedures at work here and there. Could you clarify? Can we indeed entirely bypass the insertion of the white connector in the middle of the fuel line? I hope I was clear enough in my explanations. My apologies in advance if I got something wrong. This is the first time I am doing this repair to my Husqvarna 128L that I have owned and used it for about 7 or 8 years.
The white connector is completely optional. You really don't even need one at all. I usually the connector back on the way I find it but sometime I leave it out.
I think the connector to the line with the filter is simply to provide a length (reference length for replacement) at which when you pull it back into the tank, it will stop when the connector meets the inside hole of the tank; this way you get a good length so that the filter itself can lay at the bottom of the fuel tank.
I'm guessing the other line is just to drain excess fuel back to the tank from the carb?
Home Garage Did you pull the return line all the way up inside the tank until the white connector touched the top of the tank?
Had great performance from my Husqvarna weedwackers and riding mowers.
Thanks for the comment
This video was exactly what I was looking for. Thank you very much
No problem Pat Lee
Perfect video. My trimmer is running like a champ
Great to hear!
This is way easier to follow. People be doing to much on other how to videos.
thanks
Thanks for all the information and video
No problem and thanks for the comment I appreciate it
I have like to have seen the adjustments after you installed the new carburetor. All we seen was the screw driver adjusting, but didn't see where you adjusted .
sorry for the bad angle, should have had the camera on the other side of me.
Best presentation I've seen.
Glad you think so!
Great video. Thanks for the tips on completing this repair.
no problem
Thanks for sharing this video with us.
Thank you for the comment I appreciate it
Would like to find the lock hole to replace bump mechanism on a Husqvarna 128 LD string trimmer.
I'll have to take a look to find out.
Would be great to see a complete carb rebuild adjustment video.
Thank you Phil De Giudice for the comment. It's an idea however the times I've done that the cost for the whole rebuild kit is only a little cheaper than a whole carb. I usually just suggest buying the carb instead but if I find a carb that is really dirty I'll consider it. Thanks again.
Well I couldn't answer that honestly because I've never had a high-end trimmer like a Husqvarna or steel so I don't know when I get one I'll let you know thank you
Thank you for the comment
I was so Excited after I replace my gas line it started working for about 20 minutes and then the motor seized
That's terrible news
I had a Husqvarna what do you suggest I replace it with it would sometimes work with The gas lines being rotted it wasn’t actually that bad when it worked
@@106harlem I would buy another husqvarna they're very good. They only thing I would suggest changing is the fuel you're using. Buy the premixed stuff in cans at Walmart, lowes, home depot and places like that. Make sure its the can that says 40:1 on it. Your fuel line rot issues won't be an issue anymore.
Home Garage and I believe that’s what killed the last one it was in the garage when I moved down here and it was a pain to start and I never mix the fuel because I did not know you had to I’ll buy another one And this time I will take care of it because one it worked it did work good
@@106harlem excellent
if your 128LD had issues with bogging down when giving throttle, change the main gasket. you are welcome.
Sir . You did an awesome job on your video. Very easy to understand what your doing. I have a husqvarna 123L and plug not firing. Put new plug in and no charge. How can I check the coil to see if it's working correctly. Thank you for sharing your video. I will check out your channel. I love tinkering on small engines. I get alot of my projects from the local dumpster. Some are easy fixing or I will take 2 or 3 and make 1. Thank you sir . Hope to hear from ya about my 123L
thanks I appreciate that. you're going to have to take the plastics off to get to the coil. First try and figure out the air gap between the coil and the magnet on the flywheel. I would use feeler gauges but if you don't have some, try a standard business card. IF the card will easy slide between the magnet and coil, then loosen the bolts holding the coil and let the coil attach to the magnet with the carb between them. then tighten the screws for the coil, remove the card and put the plastics back on and then test for spark.
@@HomeGaragechannel I will try that. Thank you sir
@@tracyhanson8728 no problem
@@HomeGaragechannel . The gap was good . I took off the coil and sand papered the contacts on the coil . And where it bolts to the engine and I sand papered the flywheel. Re gaped with a business card. Put it all back together and the old man fired up. Thank you sir for your help. I have subscribed to to channel. I will check out what you got and can't wait to see what your working on next. Thank you sir for your help and time 👍👍
@@tracyhanson8728 excellent work and thanks for the subscription
Good video it really helped me to replace my filter and lines thanks
Thank you Steve Collins for the comment I appreciate it
This is gonna be good, I have to replace the lines and carb. Same model. Thanks!
Good luck!
@@HomeGaragechannel Thanks!!
Oh and also what is the difference from Inside house garage and home garage?
One was supposed to be diagnostic and the other repair, but the viewers hated that set up, so both do the same content now.
Where did you learn that trick on how to cut the fuel lines??? Wow, amazing! Stupendous! ........................
Thanks for the comment. I also subscribed to your channel.
Helpful info man. Keep it coming. Thanks.
Thank you Phil De Giudice for the comment I appreciate it.
EXCELLENT Video - Thanks for sharing!
No problem Roger Amadon
College level instructions. Thanks. Very professional.
Thanks
Is the fuel line failure due to Ethonal in the gas?
Thanks for the comment. Yes ethanol gas and prolonged exposure to the gas. If the trimmer were ran dry each time I'm sure it would have lasted longer.
Do you mean 'fuel line' to be the 'return line'? You begin calling the return line 'the fuel line', as to where to connect the internal connector. Top tube on carb goes to right of the two holes, which is the return. Bottom tube connects to the left which is the fuel line to carb, and it gets a filter, right?. Why does the return line get a connector?
Love your trouble starting it!! Been there, seen that bought the tee shirt!
Thanks for clarifying it. Yes it doesn't always start the way it should.
i wish u would had shown how to adjust the carb
Sorry about that. I did explain what I did at the end tho. The cover over the carb restricts what the camera can see which means the adjustment screws . Thanks for the comment.
Did u adjust two screws or one? It’s not easy to see. I have very similar starting problem
Decent video, but it would have been better to explain what you were doing with the adjustment screws while you were doing it.
You are absolutely right. Thanks for the comment
Honestly I’ve never seen anyone struggle so much to start a 128 and I own 4 of them.
Thanks for the comment.
I own this same model and mine has started and died this way since it was brand new. These things are a pain in the ASS! My husky mower starts on the first pull everytime but the trimmer sucks, I'll give this a try and see if I can get the same results.
@@presjohnpol excellent thank you for the comment
The H And L screw was out after he adjusted them it started to clear up and run
3:15 pull the fuel line up till it won't come up any further? Or is that the other line with the plastic attachment? Hope this "old" video is still active. Thank you.
Yes it's the turn line with the plastic attachment.
@@HomeGaragechannel Thank you.
@@Coconutpelau no problem
hi. i have a husqvarna trimmer that starts and runs well when i run it in 1/2 choke. as soon as i try to run it with no choke so can get full power it shuts down. how do i fix this?
Adjust the carb for more fuel. This video should show you how.
Great vid. If the little white fuel line fitting that mounts to the tank is missing, will it still work?
Thank you scott hillegass for the comment. Yes it will still work it's just that over time the line might harden and shrink. The line will have a chance to come loose.
Another You Tuber repair shop, says it is the other gas additives. Not ethanol, that messes up the rubber parts. He says use the premixed gas. Sort of high at $19 a gallon.
it's a matter of opinion, government says it's perfectly fine to use ethanol
@@HomeGaragechannel Government says a lot of things.
Does the little hose connectors on the fuel lines serve any other purpose like restricting the fuel flow so it doesn’t run too rich?
nope, it is not needed, I think it was used to help in the production process
For confirmation, the left line with filter connects to left side of carburetor, right? When I installed new carburetor, as soon as it runs for a minute it dies. Suggestions?
yes which ever line you have as the filter will go onto the brass port that's further away from the bulb. As for the stopping, have you tried adjusting the carb to deliver more fuel?
Okay I have the filter line installed correctly. This is a new carburetor, didn’t consider adjusting. Which screw to add more fuel and clockwise or counter clockwise, how much do I turn? Thanks for your comments
I love this channel keep up the good work👍🏼
Thanks! Will do!
You should have mentioned which is which on the carb hose connection.
yes you are right
How come you didn't change the primer/ purge bulb from the carburetor tho?
this video was shot many years ago, when I didn't have a ready supply of bulbs with me. If I had done the video today, I would have changed it.
@@HomeGaragechannel I realized that bro
Thanks for an excellent video!
Glad you liked it!
Huqsvarna is a good one 👌 love it ❤️❤️ super nice 👍👍

@@HomeGaragechannel cub cadet. Weed wacker.
@@theodoreathome is it a 4 cycle?
Where can you get the diaphragm for the carburetor that you changed out? Thank you
I buy them from Amazon. Thanks for the comment I appreciate it
Mine starts and runs rough, i adjusted the low fuel and high fuel adjustment, but it breaks at idle and doesnt want to accelerate. New fuel filter, and fuel lines. The prime is good no cracks and its soft. I guess just needs a carburetor cleaning. Would you recommend just to buy a new one? If so, where do you recommend? Not sure where to get gaskets to clean.
Absolutely. Try Ereplacementparts dot com. Put in your model number and make sure the serial number is in the range it shows for that model number. Have you looked at the spark arrestor screen on the muffler? It might be clogged.
@@HomeGaragechannel yeah i did the old school way and removed it completely. The cover is there, but no filter.
@@andref713 gotcha
@@HomeGaragechannel i believe i have heard you say something close to "the carburetors you can get are darn near worse then the original"...(cheap for a reason) I just wanted to know where to look into parts or new Carb...thanks for your replies.
@@andref713 they aftermarket carbs are not a good as the original but they still work tho
Isn't it a gasket that goes onto the carb before you put the air cover on? Thanks
I don't see One on the diagrams for it, but the gasket kits seem to have one in them. So yes there probably should be, but most times it glued to the back of the filter cover. So It was always there.
Hey man! Do you have a video on how to adjust the carburator from bottoming them out?
No I don't as I usually don't bottom them out. If I did though I would probably turn them out 1.5 turns and start tuning there.
@@HomeGaragechannel alright cool thanks bud! I'll give that a shot
@@chrisfahlbush2663 thank you
I am only trying to remove the carb to get easier access to the fuel lines to replace them. I have a 128c, but my carb does not come out at all (or not with gentle force. All videos I've seen make it seem like it just slips out. Any ideas?
sometimes the carb can get stuck, to the gasket, so you might have to use some force.
I have a husqvarna 343r Wacker it's leaking oil how can I fix it?
I've never worked on that model before so I'm not sure where to begin.
I just can’t disassemble carbs and gas tanks without cleaning the outside first just common sense to me.
great common sense
Which is the L screw, their are no markings on the cover.
The L screw closer to the engine.
cool fix
Thanks Diniece Dixon for the comment I really appreciate it.
What tool do I need for adjusting the air fuel? I know it's a Phillips for the idle. Thanks!
its the splined carb tool
Did you forget to install the fuel line connector on the intake fuel line? Of course you gonna have a leak, the connector is needed to avoid that….
Great job 👍
Thank you Alan Marshall for the comment.
How often does a kill switch fail? Have two of the 128 ld's. Both have a spark. new carbs, new fuel line fresh premix gas. Adjusted the cabs L& H 1 1/4 turns Neither one will even make a sound to start.
I would also perform a compression test.
@@HomeGaragechannel What should it read?
over 75 psi at least
Great video...very helpful
Thank you SnapperKC for the comment. I appreciate it.
Which line is the fuel line and where does it connect? Do I connect the fuel line (the one with the filer) to brass port closest to the bulb? Or further away from the bulb?
I apologize that I didn't make it clear. The fuel line that has the fuel filter goes to the brass port closer to the trimmer head. The return line that has no fuel filter on it goes to the brass port close to the primer bulb.
@@HomeGaragechannel Thank you so much! And thank you for the awesome video. I just finished repairing my 128DJX , and I think it's back on its feet.
@@timhassett7302 nice work. Thanks for the update I appreciate it
@@HomeGaragechannel One last question. The trimmer starts and runs, but will only stay running if I keep it in the half-choke position, and squeeze the throttle. What should I work on in order to get it back to normal where it idles normally and doesn't stall out?
@@timhassett7302 turn the idle screw clockwise about 2 full turns. You'll turn it back out later once you get it to idle. Then turn the fuel adjustment screw which is closer to the engine about 1/2 turn counterclockwise. If it idles then turn the idle screw to a speed your comfortable with.
How about cleaning off all the dirt around the outside of the carburetor
Sure why not.
Dirt makes it reliable
do one for the 129lk model
sure If I can find one.
awesome
thanks
What tool is used for this model adjusting the carb?
the "splined" carb tool
Hi. Why do you put he original Husky weed eater return line coupler back on? Cannot you just leave a cut fuel line? Not sure purpose of coupler.
I'm not sure what your asking about, can you give me a time stamp in the video?
@@HomeGaragechannel At minute 3:18 you cut the return fuel line clean with scissor and then insert the original splice / coupler to the end of the fuel line. Not sure what the purpose of that coupler is on the end of the return fuel line. Any idea?
I see, I did not do A very good job or showing or explaining what I did back then. So that plastic piece is a splice/coupling, and it's used on the return line, as a stopper, to keep the line from coming out of the tank. Once I cut the angle piece off, I installed the splice, I then pull the return line out of the tank till it stops. Good question.
Great video awesome job

Hello! I have this same trimmer which i just bought a new carb for. Even after buying this new carb, it still wont run. I know it does run though because i tried it with the old carb.
gotcha, depending on how the engine has worn over time, sometimes a new carb might need to be adjusted to work with that engine. Other than that, more than likely the engine is flooded from repeated attempts to start it.
@@HomeGaragechannel Thank you Home Garage. Ill try it and ill get back to you if it does not work
no problem
@@HomeGaragechannel hello again! I got the trimmer to run and idle. The only problem is when I rev it up all the way, when I let go of the trimmer, it dies. But when I give the trimmer more fuel by turning the L screw, it doesn't want to start at all.
you have to be very careful when making adjustment, especially if you don't know what the default settings were. you can damage the engine
Anytime you make a video you need to show everything you do. The H screw and L screw you adjust but do not show where they are located and which one is whoch
Thanks for the comment I appreciate it
How come older Husqvarna equipment has green caps while new equipment has gray caps?
I'm not sure. Probably just a visual indicator that you didn't buy an older model.
@@HomeGaragechannel my dad's 128ld is 5 years old and has a green cap. Mine is a few months old and has a gray cap
@@js_1995x I see. It's a strange change.
@@HomeGaragechannel It's a victim of the Green Movement. Plus a Weed whacker is supposed to kill the green green grass it is whacking. The gas cap is the opening into the soul of the machine to accomplish that task, and the end result is that no green remains in the aftermath of its destructive path. Only the cold, gray, color of death.
And so it is written.... LOL
Thank you Bill Hooper for the comment I appreciate it
Why didn't you show where the L screw was and how you adjust it?
thats a good question. at the time i filmed it my videos didn't focus on tuning carbs so this wasn't meant to be a tutorial. besides that you cannot see the screws with the filter base.
