- You will learn how to properly adjust your carburetor, which is the main cause of your problem, when the engine BOGS Down when throttling up, engine Won't Start, Won't Idle or Rough Idle problems and more.
Many people run their weed eaters / string trimmers, blowers, chainsaws, hedge trimmers and other 2-cycle engines with the carburetor out of adjustment. It is very easy to adjust your carburetor and doing so will remedy many of the common problems people have.
Also, during winter months or when the equipment is not in use for a period of time... be sure to drain the fuel from the tank and run the fuel out of the carburetor to prevent the carburetor from gumming up.
Many people have asked how I got the slots in the adjustment screws... Click on the linked video at the end of this one to learn how!

Super annoying how the manufacturer doesn't slot those adjuster heads. Instead you need a dumb specialty tool.
I never comment. But Dude, you videos are excellent. No fluff. Straight to the point. And your camera usage is spot on. Perfectly framed shots. To include great close ups on intricate items. Never shake or off camera shots. Nice job!
Thanks
Simple, educational, & well illustrated. I definitely learned something!👍
Glad it was helpful!
Thank you so much for a straight forward video. Never thought of grinding a groove in it until I found your video, so thanks again!
This helped me a lot ,finally got my echo gt2000 running right again. Thank you!!!! 🙏🏽
I love your idea of cutting the screw to be able to adjust the carb
Your videos are just what I have been searching for to try to get my 2 cycle engines running correctly. From the rebuild and clean right to the proper way to adjust the carburetor. Thank You Very much.
Great to hear!
Thank you so much for taking the time, and explaining everything. I love being able to fix things myself.
Thanks for the video I have a same machine and this start on but smoke too much What can be ? I put new spark plug Clean mix oil gas mix from Lowes 40:1 This a New carburetor New fuel lines too Somebody helpme Or can be for the carburetor adjustment ? Let me know please
Without more information... it sounds like your oil / fuel mixture is too rich (too much oil in the gas). Check your owners manual to make sure you have the proper mixture. also look at the container your 2 cycle oil comes in and it will tell you how much oil to mix with your gas to achieve the mix your weed trimmer requires.
I like to run my 2 cycle engines a little rich which helps lubricate the engine better... but you don't want it too rich or you may foul the spark plug and gum up the exhaust screen.
You are awesome, I got my Dremel out, cut a slot and adjusted as described. Mine wouldn't idle and died when I used the throttle, after adjusted running better than it ever did even new.
The main thing I needed to know was the initial settings of the carburetor, which is start with both Low & Hi screws all the way in and down, then back out the Low1/4 turn and the Hi 1-1/2 turns to start with, then go from there. I had no manual and have relied on a local small engines shop and internet. You brought out some good points, including the adjustment notch cut all the way across to use a screwdriver and setting idle for no movement and the string line out to normal length for the load before making the final adjustments.
Good vid, I use a wire connector for turning the adjustment screws with needle nose Pliers
These 2 strokes are a complete pain in the butt. I have a FLYMO. Starts revs great. Then it won’t idle, stops and then very difficult, sometime impossible to restart. Leave for a couple of days. Starts/ revs great again ?..
This is my problem and I just put the carb in, I am 99% sure it’s the wacky adjustment you need to adjust the carb properly in that tiny window of time it will run
Floats in the carb get gummed up if you run tank empty and leave it residual oil in fuel dries and gums everything up and you have to clean it or new carb
U are the Goat. For Fathers day 2021 my wife just brought me a new Craftsman weedeater from Lowes($135). Fresh out the box the first time using it would brog down and I was getting upset and was going to take it back. After looking at your video it was a simple fix. U helped me save time and money. Thank sir. God bless u and be safe in mist of this Pandemic.
Thank you and God Bless you too!
Thanks for the video, this worked on a new weedeater that ran find last year when it was new, however it was hard to get it to run without leaving the choke half on this year until I seen this video and now its back to the way it should run. Thanks again, save me money from having to take it in to the repair shop.
Troy Bilt is for homeowners use. It’s not use for commercial . I always buy commercial equipment it does have problem sometimes. I use 91 octane premium unleaded non ethanol gas for my equipment
Thanks for the tips! Got my secondhand bought trimmer running, probably better than new.
I have a new craftsman 25 CC Weedwhacker that looks similar to yours except mine also has a electric start shaft hole in the casing where you can put your drill on it to start it if you buy the optional drill adapter, anyways I find the motor on these red Craftsmans are sluggish, when you hit the throttle,they’re not very reactive even after you tune them to the perfect spot. My older green craftsman Weedwhacker was a lot more reactive, when I bought the new red one I noticed it immediately, any thoughts?
Awesome video! Thank you so much! We need more people who are just straight to the point. Some videos I watch people talk about other stuff for three or four minutes before ever getting into it. This is how a PRO makes a video. I have to say that you are a pro!
Thanks
That's a Troy Bilt TB80 EC trimmer....
Thanks for sharing. Great info. @ 5.28 min of the video, you were adjusting a vertical screw. Was that for throttle movement? which screw was that? Hi/Low initial setting info is great help. What should be the initial setting for the idle screw. Mine is all the way in. Is it ok?
Yes… I was adjusting the idle screw. On a string trimmer you want to adjust it to where the head or string is not turning at idle but almost. There is no particular number of turns for an idle adjustment screw. On a chainsaw you set the idle so that the chain is not turning but almost. Hope that helps
I have a Ryobi with similar jets but high speed start lever no instead of choke. Runs great won't even come close to idle dies immediately. I cleaned screen under primer bulb too.
Thank you so much for this video! I've found others that told me that's what I needed to adjust, but none of them explained which was which and that you needed to be in the middle of bogging down between clockwise and counter-clockwise! Now I can use my trimmer without having to "jump" the throttle lower and higher to prevent it from bogging out.
Hi Have you ever removed those screws completely out and do you know that on the troybilt that those screws are different lengths? Well I need to know which length is the L and which is the H. If you did not notice which one came from where.
91 octane premium unleaded non ethanol should be fine for any equipment you can get that from Stewart’s shop
Thanks for the help, my wife's co-worker gave me Craftsman weed eater and it didn't stay running unless u played with the choke. I watched ur video and used the hacksaw across the adjustment screws to use a screw driver to make the adjustments and in less than five minutes it was running like a champ!! Awesome video ur the Greatest
Mine uses a Single D carb adjustment tool. Easy enough to find.
That was very helpful
If anyone lives near a Menards. They sell the tools for carburetor adjustment.
My weedwacker carb,the the adjustment screws was turn , need specs On carburetor video
Thanks so much for your video. I looked all over the internet on what the factory settings were... And you covered it within the last 2 minutes of your video. A turn and a half. Thank you great video.
Thank you. Your video and another similar to it saved me from having to get a new string trimmer, at least for this year.
Keep up the good work.
Glad I could help
Did this now spit black sludge everywhere.
This was very helpful. I was getting ready to buy another one. Thank you,!
what do you say when the weedeater is making metal clanking sound?
excellent videos and audios of your repairs, you should be an instructor at a school , I like a challenge that people think is a waist of time repairing a good tool that needs some repair, unfortunately i wish i was able to repair a broken heart or a broken marriage and or relationship with the same success !! merci, gracias, thank you please have a nice safe day wearing your safety glasses and ear muffs, je t'aime ma cherie, je mennuie toujours, drive safe and buckle up so you can cut more grass
You are right… A broken heart is much more challenging to heal or fix but… God can heal a broken heart and mend wounds. I will pray for you…
Sir sorry to bother you. I have craftsman weedeater that is less than 2 months old. The last time I was using it it just up and started acting like it was out of fuel and stalled. Started it and it will idle for a few minutes and die or if you give it gas just hesitates then dies. Any suggestions would be greatly appreciated. Local repair shop wants $40 hr with 2 hour minimum just to adjust a carburator. Figured if I could fix i could skip the hassle of a return.
sounds like your carburetor needs adjusting. Did you try to adjust the carburetor?... if you turn the Low side screw just a bit one way or the other you may be able to correct your problem... be careful to note where it is currently set so you don't make things worse though. Could also be a bad coil?... but unlikely since it is brand new?.
Hard to help you further than my video without being there. Maybe you have a friend who knows a little that could look at it with you... otherwise you may come out ahead just exchanging it and getting a fresh start.
Sounds like it's still struggling not hitting power band.
How did you cut the screw grooves? I'm having difficulty finding that video. Thank you!
You can buy a whole set of carburetor adjustment tools online for around $15 but if you want to cut the grooves here is the video where I did that…
th-cam.com/video/vRSRANWAnWY/w-d-xo.html
You ROCK, Brother - It runs better than it ever has!!!
Thank You SO MUCH!!!
Glad to hear
The setting to have the instant throttle response was very helpful!
Glad to hear it helped you
Exellent video, thank you. Just the info I was looking for. Part of my job in the Army was small engine repair and maintenance but weed eaters are a breed of there own lol. Just replaced a carb and coil on my remington rustler and wanted to double check. You explained everything to a "T". Well done!
Thanks for your feedback and glad it was a help
Thx in going to do this. I'll use the drimmel to create the slots.
I usually tell people to go online and spend $7 for the set of small engine adjustment tools but I can't argue with results, good show. 😁
That cut straight across is genius, because they require the special shaped Pac Man tool which are available on Amazon
That is really stupid how walscam made those so you have to buy their toolkit I don't ever go in a walmart anymore they are all junk and garbage and the food is from a sewage treatment plant
I learned a lot from this, thank you. Of the 4 YT videos I've watched on this issue, you had extra information about the carb settings and the factory setting that I found very valuable. You went the extra mile that differentiated your video from the pack! O:-)
Glad I could help
My string trimmer has a high idle on half choke...i guess its running lean or maybe i didnt prime it enough? Its intermittent though...sometimes i can get it to run perfect
If you have to run it on half choke that means you’re not getting enough fuel. Could be a stiff metering diaphragm or dirty carburetor
I got my tool kit on ebay. Search ebay for: 6/8/10Pcs Adjustment Tool Kit Tune-up Adjusting Tool for Common 2 Cycle Engine. Don't saw slots into your adjusting screws. with this kit, you will be able to adjust any two stroke carburetor.
Low is ALWAYS next to the engine if inline of airflow..
god I love my dremel! thanks for the vid, runs like a champ again!
Great to hear!
Guy said remove the screen in the muffler I couldn't so drilled a hole in it to let out more pressure and cleaned the plug and dried it real good now thing is dead wont start how did this happen, any help tnx
That should not have affected your engine from starting unless the spark plug got damaged while cleaning. You may have another issue… Check and see if you have spark and The engine is getting fuel
what weedeater is that? i have a tb 22ec with a straight shaft and from what seems like the same head your trimmer has, i ordered a new string guard and the string is no where near hitting the cutter..its like the blade for cutting the string is no down far enough as the string skips directly under it about half an inch or so...
It is a Troy Bilt
Just did this to my Troy Bilt TB22 which was making me angry because it would only run with the choke between fully closed and half open. I'll never understand why they don't slot those mixture screws. Well she runs Great now, so hopefully I'll get years of service out of it. Great Video BTW!!! Thanks
I’ve got a Craftsman weed eater that always ran fine and it started bogging down and even quitting when you give it gas. I didn’t have the adjuster tools (mine is the circle with a flat part) so I ordered those. Only $20 for a set. Ended up tweaking mine a bit and it runs a lot better than it was. I can use it again. I had already took the carb apart and cleaned it out. Diaphragm and gaskets were fine so I didn’t replace them yet. Thanks for this video, I’ll make sure it’s fine tuned now that I know what I’m doing 🤣
Thank you so much for this video. My TB trimmer ran great for the first year, then had to leave the choke on most of the way and throttle it to keep it running for the last 8 years. Finally got to the point I couldn't keep it running. Went through the carb tonight and cleaned out every passage and still couldn't keep it running. Used my Dremel to cut slots, opened up both screws a bit, and runs like new. Thanks again and cheers.
Good to hear and glad I could help!
After 3 hours of cleaning the carb 3 times, because those stupid adjustment screws are made so you need the special tool. I cut the grove with a hacksaw which took 20 seconds and turned it 1/2 turn and it runs better than new. Really tic's me off they make it so you cannot set your own screws without that special tool .
New here I have this trimmer Yard machines Y2500 Won't start I replaced new Carburetor
Your weed trimmer needs a few things to run. The greatest of these and most common problems are No Spark or No Fuel. I would check those first. If you want some helpful tips check out this video...
th-cam.com/video/qsSWMye9r0M/w-d-xo.html
@@helpinguonline according to my friend maybe low compression thats why not to start
My bogging down was caused by a faulty primer bulb. It looks fine and full of gas but after a few trigger pulls it would bog down. I guess the one0way valve in the bulb was not functioning. The new one instantly fixed it. Always try the cheap and easy stuff first.
I have a cub cudet whacker.it turns over in the 2nd stage then I switch it to the 3rd stage you run it in.it idols fine but then i give it gas and it just cuts out.please help if you can.
I think I understand what you are saying / asking. The "stages" you are talking about are the choke on... the choke partially on and I assume the 3rd stage would be the choke in the off position. If you are having problems with throttling up when the choke is off... that means the engine is not getting enough fuel.
Try turning the "Low Side" adjustment screw (the one closest to the engine typically) counter clockwise a 1/8 to a 1/4 turn and see if that helps.
First start this year with fresh gas & my Ryobi brush cutter kept bogging down when trying to rev plus idle was poor.Was going to order a new carb so checked out you tube first. Was not sure what adustments were available on the carb Stripped & cleaned the carb plus cut the slots in the adjustment screws .Thanks for pointing out the high & low adjustments.Running better than ever now
You. Shouldn't have done that. You should have purchased the carburetor tools to adjust them.
🤦♂️
Thanks so much you have the only video that actually makes sense, I did just this and got my machine working perfectly before this I was about to throw the thing in the garbage. Thank You Man!!!!!!!!!!!
Some of the new machines don't have clutches. So you will experience direct drive on your string line. I also highly suggest using premium fuel, it will save you starting problems.
Bogging down etc like in the title. Can’t adjust if it doesn’t stay running long enough to adjust.
you may have to run it at higher rpm's to get started and once you get the adjustment close it should stay running
Excellent. Thank you. I'm on this . . . .
a complete set of adjustment tools are CHEAP ... I dont recomend CUTTING on your carb. screw!
I'm not getting gas to it I've put new filter and lines and cleaned the carburetor it's still not getting gas
Are the gaskets all ok?... Is the diaphragm in good condition (not torn or brittle)? Make sure there are no air leaks around the carb too (nothing loose and gaskets in good shape). Is the primer bulb in good shape, fuel lines good and connected correctly to the carburetor (make sure you didn't reverse the lines when you re-assembled the carb)?...
cant warm it up if it only starts and dies. but ok if it ran i wouldnt be waistin sunlight watching vids jus sayin
If you can't get it started or it starts and dies... you can try to make a small adjustment to the low side adjustment screw. I would turn it a 1/4 turn counter clockwise (which will give it more fuel) and see if it will start and run. If not try turning it a 1/4 turn the other direction (clockwise) to see if that helps to get it running. Once you get it running...even a little bit you can make the fine tuning adjustments as I describe in this video.
If you can't get it running you may have another problem... clogged fuel filter, clogged air filter, gummed up carb (very common if you left it over the winter with gas in it... the gas settles and separates and clogs up the carb), broken fuel line... etc.
You can watch this video for help with getting it started if adjusting the screws doesn't work and it is not getting fuel.

Hope that helps
What if it doesn’t come on; is there a reset button
Thanks dawg absolutely amazing video brotha
No problem 👍
You never turned off the choke to setting 1. You did all adjustments on full choke. Biggest problem on these trimmers is that after all adjustments they cut out as soon as you set the choke setting to run mode, that is, standard operation. Please clarify and show how your trimmer runs on setting one. This is missing in your video.
On that weed eater #1 is full choke, #2 is 1/2 choke and #3 is no choke. If you have to run your machine on full choke it is probably because your carburetor needs cleaning, fuel filter is clogged or you have a clogged air filter... you are not getting enough fuel.
Be sure to always empty the fuel out of the tank and run it out of the carb when not using for a while to prevent gumming up your carb.
I already replaced new carb., new fuel filter, fresh ethanol free gas. Will clean fuel filter. It did not appear to be too dirty. Tried to locate spark arrestor screen on this BT22EC model. Not easy to get to muffler - needs almost total breakdown of outer front and back housing. Not sure if there is a spark arrestor screen on this model ? I will try and adjust carb. again. Thanks.
I was able to grind the notches into the 2 carb adjustments with a Drimel tool
Nice work!
thanks for the great ,easy to understand ,and i feel the correct way to adjust the wacker and blower carbs.the tip on cutting the slots is good,myself i bought the pac man style screwdrivers ,they are better in that they stay on the adjustment screws way better when the engines running.just buy them on eBay,from china they are cheap,only it takes a month to get them.
I’ve probably thrown out a dozen of weed eaters over the years not realizing that the carburetor needed to be adjusted I’m really glad I figured this out a few years ago.
Perfect explanation good job Thanks
Glad it was helpful!
This absolutely worked for me. I used a tiny saw to make the cuts across the top of the screws. This machine has been/is so frustrating. Not nearly so much now. Thanks again.
Solid video. Thank you for being informative and explaining things clearly. Some of the information you shared in this video is going to help me get my other 2-cycle equipment running again.
Glad it was helpful!
So much information in a short video. Awesome video. My troy built runs like shit right now. I'll try this.
I'm so glad I finished this video. Because at the very end, you help me with my problem.
Were do you find that adjusting tool. You were using.
There are kits available everywhere online for most every make and model included
Thanks a heep for both your videos. I cut my carburator adjustment slot as you showed and can now adjust the mix. My son found this trimmer (Yard Machine Y2500) in the garbage and would not start up at all. Needed a new bulb and spark plug plus a good carb cleaning. Everything else is pristine condition. Now works great. Thanks again.
Glad I could help
Is it the same method for a 4cycle. My leaf blower is straight gas
Depending on the carburetor… You may have just one air fuel adjustment screw… Or possibly none at all. I will have a video coming out in the next few weeks of a four cycle weedeater that I repaired. It had one adjustment screw on the carburetor and also add a limiter cap over that one screw that I had to remove.
What if I can't get the trimmer to start to warm up? It is starting to install that's all it does
If I understand your question correctly... your trimmer is starting but then it stalls. If that is the case I would adjust the low side fuel adjustment screw just a 1/4 turn one way and try it and see if it will run enough to adjust...if not try the other way. If you have already done that and your adjustment screws are off you may have to start over and screw them all the way in then out 1-1/2 turns and adjust from there.
You could also have another problem... bad coil, fuel line or filter problem... etc.
I have the very same trimmer but it won't idle, therefore adjusting these two screws while the engine is running is impossible.
it sounds like your trimmer will run but not idle. I would try adjusting the hi side while it is running full throttle and once that is set leave that screw alone. Let the rpm's come down with your throttle as low as you can (while keeping it running) and adjust the low side screw. when you turn it one way or the other the idle should get better if that is your problem. If that doesn't help you may have to replace your fuel filter, clean your carburetor or you may have a cracked fuel line...etc. I have videos on how to do those things if you need further help.
hope that helps
@@helpinguonline I already replaced all the fuel line and fuel filter. I also took the carb off, apart, sprayed every orifice with solvent, checked the diaphragm, it all looks like new. This tool has under five hours of run time. Will not idle.
Thanks, you’re video was really helpful
Glad to hear I could help you
Thank you so much for this quick and easy tutorial 😁
Yep cause there cheap made. It happens all the time so it won't happen if you get a Toro or echo or stihl
Low is always facing the engine
Thank you very much that was very very good explaining
The H screw on the Stihl FS450, has no difference all the way in or out at max throttle.
May need a carb cleaning...
th-cam.com/video/MtggiZf_x-4/w-d-xo.html
@@helpinguonline I already did a cleaning, looked nice inside though.
My H2520 would not go full throttle the first time I fired it up this year, which would only be the second season I've had it. I at first thought it was due to hastily using SAE30 motor oil to mix the fuel last year instead of 2-cycle. It ran fine with that, but I figured the higher ash content may have gummed up the filter after sitting all winter, so I planned on buying a new filter and spark plug in hopes of getting it back to normal. Instead, I performed the procedure on this video, using a Dremel tool with cut-off wheel to make the notches, and dare I say it actually runs better than when it was new!
Glad to hear that
Please show me how to turn it on 2:15
Finally got my Murray to idle. 1 and a half turns on each screw did the trick.
So what did you use to make your screwdriver slots?
th-cam.com/video/vRSRANWAnWY/w-d-xo.html
... or you can buy carb adjustment kits for around $10 to $15 now
I have a craftsman 31CC which is similar. The light blue lever I think adjust the choke. How is that adjusted. My trimmer will not run in position 3 and runs best halfway between position 1 and 2.
That means that your carburetor is not getting enough fuel and to make it run you are having to limit the amount of air your carburetor is getting. If you left fuel in your trimmer over the winter the carburetor may need cleaning (the fuel will separate and gum up your carb). You can watch my other video, that is linked at the end of this one, on how to take apart and clean the carb. th-cam.com/video/vRSRANWAnWY/w-d-xo.html
You can also check for a clogged fuel filter, cracked fuel line, loose carburetor, etc. Something is limiting the amount of Gas it is getting... most often a clog or dirty carb.
have you ever heard of a tachometer
Very helpful! Right on point and easy to understand! Thanks you!
"Cut a slot in them", son of a gun!
I knew I needed to adjust the carb, but didn't have the special tool for it, I was ready to throw this thing out tomorrow so I figured I'd screw around with it, if I kill it so be it.
I just watched your video... I feel like an idiot. "cut a slot in the screw heads", son of a gun!
I didn't have to take them out of the carburetor, I just got the Dremel out and slice right through the housing and adjusted them with a screwdriver. it's working like brand new, thank you sir.
Way to go!
That was a good idea to cut a groove in those fuel adjustment screws makes it easier to adjust
THANK YOU!! I had a trimmer that would stall if I let it idle and wouldn't run fast enough. I disassembled everything thinking it was the carb or a clogged muffler.
I cut the adjustment screws with a dremel and had it running perfectly in 30 seconds.
Way to go! Glad it helped.
