Hands down best video on this subject on the entire internet.

Awesome thanks! I used a small screw to thread into the plug and pull it out. First time in 10 years this thing has run properly!

After being in the barn and forgotten for about 6 years, I was pulling my hair out trying to figure this out. After I found this video, and drilled the cap out, 1-1/4 turns to the left and it’s running like a sewing machine 🙌

Thank you ...the guy at my shop adjusted mine Infront of me...he a great small engine mechanic but is too fast for my eyes! This is all I need and you sir I thank!

Your video was EXACTLY what I needed to get a friend's weed eater running right! Thanks Soo much!

I thought i had a dud carby out of the box. She's running sweet now. Thanks you

OUTSTANDING!! Thank you, sir. Exactly what I was looking for! Bravo

That tool to take the plug out is great. I used a pick to get it out yesterday 😂 took a while, basically broke it piece by piece. Eventually i was able to pull it

Great video! Easy instructions and clearly explained without wasting time.

the little brass nut was smashed on mine and the little plug thing you pulled out with that tool I had to break it up and dig it out with a precision screwdriver set, but I got to the little flat head adjustment and it works enough to trim my yard, great tutorial, now I can just get new fuel / air filters and a new spark plug and I should be like new.

Just wanted to say thank you very much for the video. I put an amazon generic carb on mine and could not even get it to start. Out of the numerous videos a watched not one of them mentioned the low speed mixture screw that you did. On this carb there were no caps blocking either screw but both were turned in all the way. Thank god I got the kit that had the screwdriver included. What I also noticed is they leave it up to you to shorten the return line? hose. Both nipples on the new carb are the same size so its easy to get them mixed up so it won't run at half tank and also the vent hose will push fuel out whole time. Now it actually runs to good and cuts as good at idle as it did at full throttle. Too funny. Thanks again . Now I don't have to throw it across the yard again until it need another carb.

Brought my Nadine out(SRM-210) on a job today and did some purpose field service adjustments like you did, worked like a charm. Now I'l selling all my Ryobi stuff and going back to gas.

I hated my weedeater until you came along .. thank you

You just saved me a massive headache and of course money 💰 That was a great explanation to my issue. Thanks!!!!

Out of all the videos I researched on KZfaq, this was the one that solved my problem (just one of many but still grateful). I had run the gamut of advice from, ‘tear your carb apart’ to ‘don’t buy an Echo’. Having just done a carb replacement, I knew there was something missing from the equation. The high throttle adjustment was the answer. FYI there were no caps on the new carburetor. Thanks again.

Awesome! I looked all over for that adjustment screw.

I didn’t know that type of carb can be adjusted, thank you!

Best video I have seen yet. Thank you sir.

Best adjustment video I’ve watched so far. Great job!

hey dude thanks a ton for the vid! got my 225 couple days ago. ran 2 tanks of gas through and opened up the restrictor plate... after it was spitting like yours, knew i had to find the high adjustment to rich it up. i gave up looking and utubed it.... and your vid popped up! few others out there, but yours is simple, fast and to the point. trimmer runs like a billy goat with the munchies now! checked out your channel. ive modded my husky and 2 echo chainsaws as well. if i need anymore help ill hit you up 1st... sub'd and thumbs up!!!

Awesome sir, was fixing to add it to the junk. Thanks

Interesting video, going to get that tool you showed to pull the cap. Thanks! 👍👍. Subscribed

Outstanding! My GT225 always 4 stroked mostly. I had just replaced the carburetor as part of a tuneup kit ($13.50 included carb, spark plug, gaskets, fuel lines, & fuel bulbs) & couldn’t find mixture screws. Found this great vid and the ‘ol Echo runs better than new. Aftermarket carb didn’t even have the limiter caps - score!

She hit the sweet spot I can’t wait to do this. My echo been running hella rich and my filter is soaked in gas after like 2 months. Hope this fixes my problem

Best video yet on high/low adjustment thanks bud..

I liked where you had it right before you leaned it out that last little bit. I like to hear just a touch of 4 stroke every 2-3 seconds just to be sure I'm not at all lean. Great video for sure!

Just bought a new carb for an old pas 225 and it starts and idle pretty nice but when i go full throttle it seems to not rev high as it should. going to try this tomorrow and hope it fixes the problem.. thanks for the education brother!!!!

nicely done! ive watched other videos where they use a screw to pull the set screw cap off. i just backed the set screw out and it pushed the cover out.

If your Echo with this type of carb bogs down at full throttle. You need to unscrew and remove the high mixture needle. There is a hole in the tip of the needle that will clog. Use a single wire strand to open up the passage. On mind, I turn the needle vale all the way closed the one turn open to start. Then adjust to a smooth speed. There is also a low mixture screw on top of the carb that will need to be adjusted, mine is about 6-7 turns open.

Thanks for the tuning tip sir.

Great video . Very informative. I do small engine repair and these new 2 cycle zama carbs had me fooled. I didn't know they could be adjusted. I saw a couple other videos and then yours was very informative on the adjustment. What I think the issue is with the 2014 SRM225 I'm working on is the age and compression at 8ipsi. I ordered a new replacement carburetor and I'll see if it runs after that. It just won't ifle right or work at high rpm.

Thank you for your video it was very helpful 😊

Fantastic vid

Can you show us how you tune the L screw?

Thank you so much Awesome how you fine tune the carburetor

Thank you very helpful didn't know this very helpful information did not know that my goodness thank you

Thanks, nice description,

MOST EXCELLENT VIDEO THANKS.

That was excellent-Thank you

Good job jimmy👍good video

The spark screen filter on mine was clean but removed it anyway

Great video thank you. Question where do I buy this special tool to remove caps I can’t find it nowhere .

My srm 225 is new , ran 3 tanks of gas figuring it needed broke in but yeah mine did the same sputtering at max throttle , took that plug out and adjusted till I hit the spot where the engine was going back and forth from sputtering to smooth … tweaked it another 1/16 turn to lean where the engine was mostly smooth, tested in tall grass and it did have a bit more power…. Oh and when I adjusted carb I bumped the line head to get max line out to kinda put a load on the motor

What is the settings on the screws

Man!!!! Great video thank you…

can u tell me exactly what model screw drivers i need ....

Great video! I have this same unit. Where is the low adjustment located?

Fantastic!!!!

Can you use the same cap removing tool to remove a cap from a echo pb-250 (blower)?

Sounds good. Did the echo have a muffler mod?

I have an echo SRM 255. When I go full throttle it barely spins, almost like there is no power and will almost die down and turn off. This is my first weed Wacker, I bought it new a month ago. I will try messing with the screws, but I'm hoping this is the issue. Any other tips?

My SRM 225 runs wide open and If I squeeze the throttle it doesn’t rev. Can you please tell me what I need to do? Thank you.

What would you adjust if it won't start after hot unless you put on choke pull once then take off choke starts right up?

Great video and explanation. I have this same weed eater and have a question: After like 10-20 cord pulls on cold start, the tool fakes like it’s gonna idle, then dies. I can pull it a few more times and it’ll idle maybe for longer then dies. I then open the choke more and hold on the throttle to hopefully get it to catch and just run from there for however long I can get it to run. Do you know what I can do to make it run better? I wouldn’t know If I’d need to adjust the high or low settings of the carb screws shown in video. Would really appreciate a reply on this!

100% excellent video

Paper clip, heat the end to red hot. Put into cap let completely cool. Remove cap.

Nice!

Having a hard time getting the low end cap out. Might have missed and squished it. Any advice getting it out.

I did this to mind. It worked for about 10mins then doesn't so I tuen alittle more it only works for 10 min. The muffler is no dirty. What can it be?

That’s the one we have

Hello… Does that 2.5 MM Echo tool also removed the brass part of the plug too? Or does it only remove the black plastic piece of the plug?

My SRM 3020 Echo trimer doesn’t have a slotted screws. What is the proper tool needed for making the adjustments? Thanks

Great video forsure!!!

New filter, plug, carb. Now my trimmer starts. But at high idle it slowly loses power. The spark arrester philip heads are rounded so ill have to remove them this weekend. What else could it be?

I have a gt225 which looks exactly like the one your working on. The thing leaks gas, especially when the weather warms up. I’m thinking it’s a venting issue. I have replaced the grommet, and all 3 lines as well as the fuel filter. It’s sitting level on my bench but still leaks fuel. The vent is new as well. It’s screaming vent issue but would appreciate your wisdom. Also, where do you get that echo tool? Thank you for your time!!!

Can you use the tool on the low side cap also? Where did you buy the tool?

I thought these usually came running too lean per EPA?

Where did you get that echo tool

Could I replace the solid echo triggers with the flared triggers that these have? I hate the solid ones

This might be a stupid question? I just bought an Echo srm225 brand new, mine sounds like the one in the video before you adjusted it, my question, will it hurt the engine if run like that? Or should it be adjusted? Also in all my old trimmer i ran 40:1 can fuel. With this trimmer i bought the echo 50:1 can fuel. Will it be ok running 50:1 echo can fuel?

I just did that with the puller you have but do you half to put the plug back in it’s on a echo blower 255 ln if so how do you put it back

Where did you get that tool from ?

Weird, my 225 has a Zama butterfly carb but had EPA limiters. After tuning my Stihl saw the same way I did my brand new 225. Both are absolute animals now

What fuel goes in ? 50 to 1?

Let me ask you can you burn the engine if its running liner

When you adjusted it, is it feeding more or less fuel?

Hello where do you get the tool from ?

I have a new carb, plug, air and fuel filter. When I replaced all these, weed-eater ran like new. A couple use and now it dies when I press the trigger. (GT-225). I checked the spark arrester and it was clear. Not sure what else to check

thank you so much that dang cap caused me hell.

My guy!

👏🏼👏🏼👏🏼👏🏼

Does counter clockwise richen it?

What about echo 2620 I only see one screw on top?

Very good, but remember to clean exhaust port and muffler before testing carb settings. Fuel variations such as gas quality or ethanol content or oil amount per gallon can affect fuel-air needs.

didn't have an echo plug remover... just drilled it out.

Great help to me today. Thank you!

Question my srm225 starts up fine but no power. If i take off the air filter it goes to full power. Will these screws fix that problem?

The low screw does not turn. I removed the cap and found the small slotted screw but it just does not turn.

Will that cause it to flood ?

Looks like you're turning it to the right... Clockwise.... What if we have it turned all the way to the right ????

Really informative video, it needs more volume though

Awesome ta

Mine runs now but does not rev, adjusting the screw does nothing for mine

Mine keeps flooding and I recently installed a new carburetor

So a drill bit will get the cap off when you break through you will know it! Nevermind that tool.

Where is the low rmp adjustment screw

Am ibthe only one that doesn't have a 91075 puller in my pocket at all time?

carry that screwdriver in your pocket every time mine viberates loose. have to ajust it

Thank good I found this video I was about to throw it out owners manual doesn’t tell you shit🤬

Mine dies when I got full throttle 🤷🏻‍♂️
