Thanks much appreciated this is the best video I have found yet on this subject lots of searching and everyone has videos telling you the same old shit about the plug and where it's at but nobody shows how to tune it people know the plug trick cause everyone and there brother has made videos on it like it's some top secret and there ain't 1,000 other attention seekers videos on it.thanks again for the much needed and helpful video
Thanks for the kudos. Glad I could help.
Cuantas vueltas le tengo que dar al tornillo para ajustarlo ayuda por favor
@@BearsWorkshop how many turns does the adjusting screw take please ..
I thought you can adjust the carburetor with just the brass piece just by removing the black plastic plug?
I found an Echo GT 225 in the neighborhood trash. Looked brand new. Got it running, pretty good, but the high end was lousy. Saw this video and adjusted via it. Runs great for the price. $0.00 Thank you!
Thanks for this detailed explanation. My new (year old) Echo 266 trimmer had never run well and I had no idea where this adjustment screw was. So despite your fine CYA advice to leave it the hell alone, I made the adjustment after throwing the little brass jobber-do away. I am writing from the cell which had been reserved for a politician, but my trimmer now runs great! I hear it outside the prison wall, trimming away like a champ.
Sorry to hear of your incarceration but having a trimmer that is running properly is definitely the upside. Please understand that cells can be shared and you might shortly have company. Please subscribe if you haven't already as I will be making a video on how to legally break out of prison.
Thank you for showing me that there IS a PLUG! I thought that I was just without any ability to make it more fuel efficient! I think you just helped lower the carbon footprint AND kept millions of carburetors out of the landfills!!!
🌎✌🏼
Thank you much kind sir!! our weed eater was doing the bogging down thing...it wouldn't stay running... so my boyfriend bought a replacement carburetor and it still did the same thing... he came in all defeated and frustrated... We did one Google search & found your video and watched it ... took it back apart and removed the little brass piece that was preventing our success and now it works like a champ thank you very much! Some heroes don't wear capes! :-)
Glad we could help.
My Echo GT-225 had been bogging down over last year and this year it would simply cut out (shut off) when applying throttle. This saved me a trip and #'s for repair. Thank you so much. I ended up drilling the plug in the core then was able to pry the outer circle of it out very easily.
Thanks for sharing. I am glad this helped you out.
I had to drill my brass plug out too, it was not easy getting the brass plug out, but it sure did help out a lot
I bought a new carb because mine was doing same thing. New carb still ran off, THEN I found out there was a hidden adjustment...lol
Was the exhaust port clogged?
@@ThisTimeTheWorld If you're asking me, no. I followed this video step by step but the brass plug did not come out as easily as in this video. I had to drill it out. Good luck with your fix
This is the best explanation on this area. Thank you.
Definitely the best, no bs, thorough video Ive seen. No wasted time, straight and to the point. I subscribed. Many thanks.
Thank you. Appreciate it.
Finally First video I watch someone showing how adjust a echo carburetor step by step, thanks for the video. Others just told you instructions, congratulations....
Cool, thanks!
Damn EPA and their brass plugs. Once I drilled it out, adjustment made my blower run like a clock. Thanks for the video, well done
3 year old Echo 266 weed whacker randomly bogged down after cleaning the carb day prior. This is the first thing I tried and it runs better than it ever has. I had to drill the brass piece out. Thank you sir
FYI before you do that, check your exhaust screen to see if it is plugged but this video was WONDERFUL. (I love learning)
Thank you thank you so much.
Your step by step clip help a lot. My weed eater was not starting at all. After I was done following your clip, was off to weed eating.
Gracious sinyor
I am about to install a new carburetor on my Echo weed eater. This video is quite helpful with the installation of the kit.
Clear instructions and great camera work to see the details of how to do it. Great work and very helpful! Thank you!
Glad it was helpful!
This was much appreciated and worked fantastic. I had just replaced the fuel lines and pump and couldn’t figure out for the life of me what was going on. Your comment about the weather (it’s been well over 100 in Texas) and how that piece needed to come out was spot on. Just knocked out the yard and much thanks!
Awesome information for us DIY r's left in the world. Its too bad Dads don't work on lawn mowers anymore or pass Vidal mechanical knowledge anymore. Thanks Bear.. God bless you
Thanks 👍
I just did the same thing to my neighbor's Echo string trimmer Saturday. It had barely any power and needed the carb passages cleaned out anyway from sitting for 2 years with ethanol gas. After the clean out It still needed the main jet adjusted richer. I adjusted the needle out until it was too rich and was not running clean, then back in until it ran strong. Happy neighbor. I've done this to my Echo edger, Stihl Chain saw and leaf blower. thanks for the video.
Nice work!
Thank you for this video. I’ve never adjusted any sort of carburetor and this was easier then I thought. I appreciate it
Installed a new carb and it kept bogging down under throttle. This fixed it. Thanks!
I mean it does way in the manual if your above a certain elevation you might have to pay someone to tune your carb lol...
I have a 12 year old GT225 and just recently have throttle issues, cleaned out exhaust and replaced carburetor but was still having the same issue. Your advice made the difference for a smooth and steady run even at full throttle. Thanks a million! Saved me some serious $$$ and hopefully have thus Echo going for another 12 years. (🤞🏼) Blessings
Hey everyone, let me know in the comments if this video has been helpful to you.
Helpful but what about the low end screw on the throttle arm?
@@cliffordvancooney99 Are you referring to the idle adjustment screw?
Bear's Workshop thanks man great vid
My echo idles fine and goes to full throttle, but it bogs at 1/4-1/2 throttle. I’m stumped. I’m probably going to just buy a new carb.
I was getting ready to buy a new carb because mine wouldn't run off of choke. This fix made mine like new again. Thanks man great video!
No problem, thanks for watching!
I fixed mine this morning
Thanks friend. I just bought 3 of these and 2 are all choked out. I’m sending this to shop mechanic
Fantastic video awesome thank you so much for actually getting to the point and not taking forever to make the point There are so many videos online are such a waste of time this one is not thank you very much for sending this out to us it's nice to know that there is some sanity left in the world on how to just get shit done😅
This video is exactly what I need. I will do this first thing tomorrow! THANKS!!
Best video about adjusting the Echo carb.
Thank you!
Agree, earned a like a subscribe here
Thank you. I had to drill out the brass cap. This saved me so much trouble. Thought I was going to have to buy a new trimmer, or at least a new carburetor.
by far the best explanation and presentation on how to adjust the echo. Thank you for sharing your knowledge.
Thank you. Appreciate your comment.
Bear. This was the BEST Video on the adjustment and fine tune up of the carburetor on TH-cam. If someone can’t follow your Excellent instructions then they need to just take it to the shop. I never touched my carb before and I did it in 15 mins. Thanks Again Bear.
Thank you Steve!
Wow!
Just yesterday I was looking for a adjuster on my echo....
I knew there had to b a way to adjust my throttle!!!
Thank a million bro!
Glad I could help.
The best 👌 straight forward video I have yet to view.
for those having trouble getting the cap out, I used a very small drill bit to pop a hole in the plastic cap inside the small brass piece. After i broke through, it all popped out with the bit
Excellent instruction. Thank you very much.
Glad it was helpful!
I'm a diesel mechanic that is a very impressive Saw shop I love the cubby shelf
Very helpful straight forward video. Thanks.
Thank you.
That adjustment screw is for high speed only. There is another similarly plugged adjusting screw (on many models) down inside the center of the plastic plate that rotates when squeezing the trigger and it allows adjustment of the low speed mixture. As this video is 4 years old, I suspect no one will read this.
Yes someone read it😂. You just solved my problem after days of searching. Thank you.
Great job. Mine is running like new now.
Thanks a lot. Now I can do myself.
'Don't mess with the emissions' I may or may not have laughed out loud.
This actually made it burn cleaner and pollute less - - and FAR less than scrapping the trimmer and buying a new one.
Love the TEE
Thanks! Very informative.
Glad I could help!
THANK YOU FOR YOUR VALUABLE INFO.
Little trick use a phillips screw as a easy out and pry out. Also I use a digital rpm gauge to get max power taught us that at echo class I went to years ago.
Excellent tutorial. Thanks!
Awesome video! Helps much appreciated.
Brilliant explanation and demo. Thank you!
helpful as always and easy to follow, thank you
Glad to hear. Thank you!

Off to the races. 🏁 "gentlemen, turn on your engines" 🏁 LOL...thanks. I have an Echo blower that needs an adjustment, probably same engine & carb. 👍 Very Helpful
Glad to help!

Thanks Bear !
I'll probably be doing this, I watched a few videos, yours had the best step by step instructions. I have an Echo GT-225 and the stupid thing has never run right. This year she won't stay running, being over 8 years old I ordered a replacement carb with other components to get her back up and running. Knowing the way they adjust the carbs from default it is a guarantee you'll need to adjust it.
I hope you ordered an oem carb. The cheap $15 ones on amazon and eBay are junk.
Bear's Workshop Yeah that’s pretty much what I ordered. I guess I’ll need to try cleaning mine then.
I’ve ordered them in the past to try them with the thought that the other parts that come with them will make it worth it if the carb doesn’t work. Most often the carb doesn’t work. The oem is worth it. Try ereplacements.com or partstree.com for the right stuff.
Bear's Workshop Thank you sir! I’ll probably give it a try, and definitely try to clean my original carb out if that’s the case before ordering a new oem carb then. The only reason I did was it had great reviews, and for the price I said what the hell
Excellent video, thanks for not adding a bunch of cute BS and getting down to brass tax.earned a follower for certain.
Much appreciated!
Very nice video man!!!!!
Appreciate it!
Great video lots of help 👍👍👍👍👍
Glad to hear it!
Thanks buddy
Thanks, I learned something new about Echo. My machine is 4 years old. After a new carb., fuel lines , spark plug and fresh fuel mix . I cannot get it to rev up like it should.
I had the bogging down problem with SRM-225. Would start, idle, and die when I pulled the throttle. I saw a few other videos before this, but I think this video was the best description of the process.
My carb is running rich now and we’re back to slice ‘n’ dicing speeds without boggy death.
FWIW-I’m not a fan of fast-forward work because I like to see every step, but that’s how I learn. Maybe you could post zoomed regular-speed videos in a playlist for beginners as an accoutrement(you already have the content, why not offer variety for different audiences?).
I will reply with the results of field trials of my carb adjustment after I go hack down the jungle that has grown while my trimmer has been out of commission.
Thanks Bear!
If it's time to replace anything carb related, I offer this suggestion: I ordered this replacement kit for my PAS225 on Amazon and decided to switch out the carb even though the problem was a rotten gas tank grommet where the tubes go in. The replacement carb features an adjustment screw where the brass 'blocker' used to be on the factory part. It even includes an adjustment tool (screwdriver): Mannial RB-K93 Carburetor SRM225 Parts Tune Up Kit fit Echo Trimmer I was able to switch out the entire carburetor in about the same time it would take to remove the brass plug.
Those $17 carbs on Amazon and Ebay are junk. I have bough ta few thinking that if the carb didn't work. I would have a new filter, gaskets, fuel filters bubbles and such. So no real loss. I only buy the OEM ones now. The point of taking out the brass plug is to adjust the carb. Once the plug is off it is really easy to adjust at anytime after that. We have these carbs on about 15 different tools. So adjusting them would make more sense.
Good video indeed.i aprechiate it..gonna try it 2moro with my echo blower..cheers m8..stay safe..good luck 😁👍
excellent video, thanks!
Good video and good information
Great!
THANK YOU FOR THE VIDEO NICE...
Great video thank you!
Good Video. When you open it up to remove the brass plug, the Carb. Screen is there too and should be cleaned. That also might be why the machine isn't running right.
Well done video, I have an echo gas blower, wasn't running changed carburetor, I need to do more investigating
Yeah mine I only bought last yr mind you I use it like three to four times a week and it's not running good all of a sudden its bogging out ,so I'm gonna try that thx for the 411on that .
I hope it helps.
Sweet!
Good video, you should have told them about the hidden high speed adjustment screw on top in the center of the barrel shaft nut. It's needed to maximize tuning
Wasn't that the screw he was adjusting? Isn't the high speed screw typically adjusted with the engine under load like he demonstrated or was that just a mistype and you meant the hidden "low" speed adjustment screw that's set while engine idles? Cuz now I'm a bit confused.
@@KB-ie7jr there are 2 hidden screws on that carburetor
@@brianpulliam47 well how about you tell us Mr. Pulliam.
That's the low speed adjustment. Not the high speed
One video indicated finding the sweet spot by going back and forth between both screws a few times, listening/adjusting as you go, as in this video, so both adjustments are optimal, in accord with Pulliam's Law.
I didn't remove the brass piece on my echo srm210, however there was a plastic camp on the inside of that piece of grass that I had to remove when I replaced the carburetor diaphragms and I can see the screw in there that's how I tuned mine. Also on my low speed needle valve on the top of the carburetor there was a black plastic cap in there as well that I had to remove and I've been able to retune my carburetor does brass piece on the back on my high speed needle valve really need that brass piece to be gone
Is this a run on sentence or what?
We just going to ignore the low adjustment?
Great Video. Do you by any chance know what Echo's recommended RPM' is at full throttle and idle? Thanks Again
Any tips for getting that cap out? I’ve used pliers, screw drivers, and a drill bit… no dice
Do you answer questions about this trimmer? If you do, I replace the carburetor. I thought I had the gas line connected wrong, so I reversed the 2 hoses, but some problem. No gas to the carb
I have an echo 8010 leaf blower and it ran before I changed the carburetor but was very rough, then I bought a carburetor that wasn’t lemon and now I can’t get it to start without starting fluid and it will barely run for a few seconds and die. I put new fuel lines and filter and I made sure the lines were on correctly. It seems like the fuel mixture is off but I don’t know for sure because I can’t get it to run long enough to tell. I heard that rule of thumb is turn it 11/4 turn counter clockwise to get started. Anything you can tell me would be much appreciated
Chinese aftermarket, Zama type, I have two identical for echo trimmer, neither carb will tune in and run as the original. So I have been trying to figure out why. Opened all for a look at each of the metering system. Found that both aftermarket had a different needle fulcrum arm setting compared to the factory OEM. OEM was set level to the height of the metering gasket, both aftermarket were above the gasket at different setting each. The aftermarket both ran extremely rich even after turning the main jet needle all the way closed. Then attempted to close the low speed idle needle to see if that would reduce the fuel as the two jets are the fuel entry points. I was able to make it idle by turning the set screw for opening the barrel more and closing the needle to some point of equilibrium. Then fine tuned the high speed main jet at wide open to get its best run out. End result was still not optimum. The high end would momentarily switch between a smooth high rpm then drop back to a to rich stumble lower rpm. These switches lasting only around a second each.
The second aftermarket I attempted setting the meter arm at a position slightly lower than body level hoping that this would reduce the amount of fuel. Well it did just that but then could not get enough fuel for idle and no matter the idle speed set it would die. So I set it back to level with the body and it functioned as the first one after setting the needles. My conclusion is the fuel passages, needle closure points are just to large, on the main, compared to a high quality factory Zama.
This is really good to know as this indicates WHY I'm facing my hopeless situation. A leg up on mechanics is always welcome.
What about adjusting both high and low? Will this work on an Echo SRM-3020 weed trimmer?
This is probably a long shot but I live in hope! I have problems with my hedge trimmer carb. I cannot find anyway of adjusting the carb. It’s a German motor and the carb is a SK-C26LE/SA. Can you help me? Have you ever heard of it?🤣
If boggs down under load, does that mean too rich? Have an echo long arm tree saw
Thanks for the info
Any time!
Do they have those plugs on jet airliners also?
I’m trying to adjust my arm 266 and have two adjusting screws, one below the purge bubble and one on top. I have tried everything I know and still can’t adjust. Should I adjust the idle screw.
Good video but you didn't show where to put the screwdriver into.
It looked like you were putting it between the fuel lines but not sure.
I have a old echo pb200 blower.i purchased a carb offline.it has access to both the high and low speed screws.when I attempt to adjust the low speed screw.where it seems it should be set the blower starts smoking like it's running to rich.so then I lean it out some.what I noticed is I'm able to start the blower with no choke.the primer bulb seems to be functioning the way it should.it also will run with the choke on when the engine is hot.what iam doing wrong?thanks
I found this solution a year or 2 ago because my weedwacker kept dying when reved up but didn't want to "alter" my equipment too much... after replacing pretty much everything else short of the carb it's self I finally went and got that plug out (had to drill the damn thing out >.
That brass piece is a limiter that stops the screw from backing out to make it high speed run richer! If you need to wind the screw in as was shown to make run lean then it was a big waste of time removing the brass limiter! Now for the low speed screw it's screw is in the center of the barrel where the throttle cable connects!
How.do I adjust the low speed screw and how do I know where to position the throttle cable?
@@jamesbronze7135 Mentions all this bs and no reply. Wtf🤷♂️🤷♂️
Clean the exhaust screen too, if you have one! Also I suggest using alkylate fuel only.
I'm working on a SRM.210 and it will start with some carb cleaner but won't stay running stalls ans dies
Wonderful video. Thank you sir. Sad they instal “safe guards” when in fact a poorly turned engine outputs MORE emissions than an “in tune” engine. Okay added power, better fuel consumption, longer life out of your motor. It’s just good sense. But this is the throw away mindset we live in now days. Spend couple hundred bucks, throw it away in 3 years and buy a new one. NAHHH. Or fix it and keep that sucker running as long as possible!!
Thanks so much Bear. The old school carbs had a low speed screw (not the idle screw) as well as a high speed one. Do modern echo carbs not have it any more? Great video and I really appreciate you giving up your time to help us all , cheers, Simon, Devon, UK.
As far as I can tell the newer stuff does not have the high and low. Just the one. There maybe Echo that might but is not on any of the equipment that we run. Hope this video helped you out.
The low speed is under the throttle cable screw....seen it in other video... it also has a brass plug
I’ve watched this twice now Bear and now I’m getting asked how did I get that thing running so well? Thank you Thank you and Thank you again. A lot of folks have asked about 2nd screw, the one on top of throttle body- I understand that has nothing to do with throttle adjustment- any idea what it does adjust?
essentially it just holds the throttle open... you can put it all the way back and just hold the throttle part open yourself and it's the exact same thing.
king james488 I would disagree. If you turn it clockwise it lengthens itself and then restricts the amount of fuel that come out if the main orifice and opposite if turned counterclockwise. Definitely changes the idle and wot operation. There is a delicate balance between the throttle set screw, the main and the low speed adjustments.
@@magicone9327 "restricts the amount of fuel that come out of the main orifice"... ya, your describing what the throttle does.
@@kingjames4886 The screw that he’s talking about “on top of the throttle body” is the low speed needle not the throttle stop/idle adjustment screw you’re talking about. It is also on top of the carb but off to the side.
@@kingjames4886 That’s the high speed needle. The low speed is under a plug inside the middle of the rotating assembly on the top.
Echo has a tool to remove the brass "plug" thing without disassembling anything. And it's simply a 2.5mm left hand threaded tip with a handle. That brass cover has a female left hand threaded socket. It's really easy.
Why buy some expensive tool from Echo for a one-time use?? Barry's way is so simple, and even other vids show easy ways of getting brass plug out without removing any other parts.
How many hidden adjustment screws are they
My GT 225 is a couple years old and has always started easily and has run great. This year, it ran rough and was hard to start. Almost like it was not getting fuel (the bulb would not fill). I disassembled the carb, cleaned the clunk and fuel lines and it ran better but often bogged down after a short while. Sounds like I need a carb adjustment, as well. Do you agree? Should I be looking at something else. I'll give your advice a try before I buy a new carb.
Adjust the carb first. Then also check compression.
Just curious why didn't you just use a small screwdriver to turn it without taking anything off? It just seems to me there was a lot of needless disassembly. I just learned of this and adjusted it without taking anything off
