2 carb. installed on my Echo srm-225 (12 years old) paid 22.00 for carb. 1st issue bogging down, changed carb, 2nd issue a few years later , ran for a minute and stopped, changed carb....runs great again...for 22.00 $ for me just buy and change, not fooling with carb kit. Great video you posted for viewers !

Professionally done video with great information. I've grown tired of rebuilding little carbs. Replacements are so little more and so much more reliable. Thanks!

Fantastic! Thank you for the captions explaining the carb adjustment process. Best explanation I've seen yet on this process.

Just put in new carb & fuel lines..started 2nd pull. Great video!

My brothers and I used the handles of large serving spoons for taking off bicycle tyres so that the inner tubes didnt get pinched, the handle of a smaller spoon would work to put that grommet in without damaging it, great videos , love your attention to details and thoroughness

Great job. 5:30 The air filter rib installs parallel with the housing rib. These lines are also reflected on the outside of the cover.

Thanks to this excellent tutorial, my Echo SRM-230 runs like new after a quick carb change. Thanks!!

super helpful. started on first pull after installing the replacement carberator and kit. Thanks!!!!!

I took a Husqvarna stick edger and a Husqvarna string trimmer for carburetor work once. The replacement of the carburetor on the string trimmer was reasonably priced. The stick edger was "lost" and I never saw it again. Thanks to your videos and more time in retirement I try to do my own repairs now.

I have never seen a carb with the adjustment screws like that! Very interesting. I'll definitely keep an eye out for them. Great video!

You know me, I’ll repair it. Shop rates plus parts is almost always more than the value of the piece. Great video

I would rebuild first and try carb later...so far new carbs have not worked for me. This video is a very complete repair guide. Thx!

The info on the location of the adjustment screws 👍👍👍. Thanks for sharing.

Nice visual video with some interesting information. With regards to having petrol lawn tools serviced. I usually try to repair my tools myself, however, it depends on my availability of time. I have a good lawn care mechanic close by so he is a good fall back in case I get into difficulty. Thanks for sharing.

I have two new Echo carbs ordered and this helped me a lot.

I would replace it myself I just need to learn how and this video is very helpful for that thank for the great information. A full service of my whipper, mower and blower can be expensive!

Hey I do it myself. But also work in a small engine shop and have rebuilt or replaced hundreds of carbs. Excellent video Have a nice day

Had the same problem with mine. This video really helps.Thanks.

Indeed a very good value when it comes with extra parts

You are definitely right about running a little rich on the high speed needle. Too many people adjust for the highest rpm and as you said the engine will last longer if you richen it just a bit. Your advice is spot on as always. Wish you had merch so I could get an HG t shirt.

I did the exact same thing last week. I hadn't seen this video yet, but I agree it definitely runs better than it did 3 years ago with the new carb kit from Amazon.

Cheap replacement carbs are fantastic, I’ve used quite a few of them and have rarely had issues.

I pop out the fuel return line, insert the grommet and then reinsert the return fuel line. I find it’s easier to get the grommet in with two lines instead of three.

What a great video, I have that same exact model and I’m super satisfied with it 😎

Thanks for such a great detailed and complete video!

I found that a half inch socket large enough to cover the grommet but no so large it hits the fuel filler neck, was the easiest way to install the fuel grommet with the fuel lines. Learned the hard way by punching a hole in the new lines they are remarkably soft and easy puncture brand new.

I wish i would have seen this video first... I have an Echo SRM-225 that's been great for several years, but wasn't running at top form... so I bought the full carb kit and installed it. All good, but I did a few things incorrectly... first the replacement vent line from the kit is too long, so once it fits into the tank it's too low in the tank and bleeds gas instead of air. Fixed that. Made a gallon of 50:1 mix with fresh fuel, and it fired up nicely... however it just wouldn't stay at high RPM and wouldn't cut efficiently. So I did exactly what you described in your video... adjusted the high RPM screw and now it trims like a new unit. Glad you mention that the new unit doesn't have the brass cap; I'm surprised they're allowed to sell them without the cap... I thought that was an OSHA requirement in the US... guess not! Thanks so much for sharing; your the video/sound quality is fantastic, and most importantly you cover topics very well.

I have actually put a leaf blower carburetor from an echo backpack it has the primer on the bottom it works !!! Different style of carburetor but everything fits it wouldn’t run with the replacement carburetor it had 90 psi pressure but when I put the backpack blower it ran. Got that idea from KZfaq

Thanks for the great video. I would buy the part and do it my self.

Hi, especially on older two stokes I often times have problems with replacement carbs. I try to rebuild if possible. I love the replacement carbs for older Tecumseh's and Briggs motors. Never a problem.

Watched a few of your videos really good I have just pressed the sub button 👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻

i've been tinkering with my two wackers (one for grass, one for brush) trying to get them going again. Ordered replacement primer bulbs for each, because those were visibly cracked since last year. But just had no luck getting either to run for more than 15 seconds at a time, or being able to idle but dies when I hit the throttle. Finally decided to just get new carbs. I'll be putting those in this weekend.

I have and regularly use a Homelite ST 385 17” duel cut weed wacker. It was found on the side of the road in a free pile. I took it fully apart cleaned and serviced it and reassembled it. I now hate rust even more along with reverse threaded bolts and spaner clutches. But any way it works great, full choke is useless as it causes it to die but it has a start assist that holders the throttle at about 10% until you touch the throttle handle. I also run it with a fuel mix of 32 to 1.

Brilliant video, thank you so much. I've watched a few videos on the topic but yours is the first that showed how to adjust the H screw in real time with the sound of the motor.

I will always try to fix it first. I bought a replacement on amazon the entire package was 18.00 an free shipping get beat that deal. It was running a little slow but you showed bt how to fix that Thanks .

Being stubborn I bought carb parts from my Sthil dealer for my MS250 chainsaw. That was easy to do. Unfortunately it still didn't work. Eventually I gave up and ordered a kit on Amazon. A lot of parts came with it which I din't use. Works like a charm now.

i would try to fix and or buy another carburetor and go from there. Thanks for the video.

I have way too many of these gas powered trimmers but maybe now that I've watched your video I can get some of them working again. Pretty sure it'll be the spark arrester since I run them with a bit more oil than necessary. I do this because I've had one throw the piston at 50:1. Thanks for the info. New Sub.

Purchased three "full carb kits" from Amazon to fix three different lawnmowers and every single one of them run BETTER than ever. Cost around 18 bucks each. Include fuel line, spark plug, multiple primer bulbs and filters. Repair shop wanted 60 for their carb. Took me all of 10 minutes.

I have the the exact Echo. I took the carb apart for cleaning and dropped an internal part in the bottomless depths of the garage, so I bought the Amazon carb and also found it to be just as good, if not better for the same tunability reasons. My Echo SRM 225 has been a very reliable and quality weedeater for many years now.

Great vid man keep it up I just watched your other vid on other channel

Thank you great video. I will replace my carburetor

I did all this twice over 5 years before it lost compression. It was a good tool overall.

On one of my trimmers, I cleaned my carb at the start of the season to get it running good. On another, I ordered a new pull-cord assembly for it because the old one broke and I have not installed it yet. Since I have two running trimmers, it is hard to take the time to work on the third. Last season I had to replace the diaphragm on the one I just cleaned this year. I will probably need to replace it next year. Not afraid of working on these things and I do appreciate the videos to show us tips.

Nice clear explanation and you have a new subscriber 👍

Intro never gets old

Great video!!! Keep up the good work!

I'd get a kit or a new carb. I also had to replace the grommet on my Echo when the alcohol started flowing. Been fine ever since and I re-did the fuel lines then too. Thanks nd Blessings

Wow great idea with the exhaust

I had that problem with my blower. Bought an aftermarket an it works great

I’ve worked on 2-cycles for decades, and they’re fun to fix and maintain. I’ve got two SRM 2100 units (one’s trash-picked btw, so that one’s free and the other one was a gift from a friend) and they’re OLD!😂 Just bought carby rebuild kits for both (made sure carby type before ordering diaphragm and metering parts) because of constantly stalling after idle. But yeah, much easier to slap in a new carby than tryin’ ta save an old carby, especially when the old parts pool drys up. Oh yeah, I’m big on stocking up on spare parts like carby and fuel line grommet kits.

I suggest getting the tool kit. It will help u so much.

Great information! Thanks for sharing.

Awesome job sir, thank you for a wonderful video, very informative

Like tuning a guitar. Nice work ..As usual. Thanks for making these vids.

I would definitely repalce it myself great video

Exalent instructions on this process and would save time and money over taking it to a shop. But it would be helpful if you listed the part number of the kit ad I like the idea of adjusting the carb to the motor that may have some hours on it.🖒

Very good thanks. Will have a go next time.

Gray job replying to comments! So many channels don't and it can be really annoying.

I have a trimmer an a old leaf blower replaced fuel lines on both but still running crappie , bought new carbs for both on eBay, $10.00 each ,now they run like new!!

Good video. I have an Echo ES-210 Blower that I am struggling with right now. Rebuilt the carb with OEM parts. Replaced the fuel lines and filter. Fresh air filter as well. It starts cold easily but struggles to get to full power. It takes a few seconds. It idles smoothly but won't stay running. It will shut down. The idle is smooth but it seems starved for fuel. It is the OEM/original carb and old. It is pinned so it might be easier to replace that to try and drill out and adjust. I switched to non-ethanol premix and it runs smoothly when running on this fuel. I am thinking that something may wrong with the carb that wasn't fixed in the rebuild. I am checking the spark arrestor next.

Use carbs off amazon and ebay all the time, for the most part they have worked well and are an excellent value.

I was working on an old 1962 wheelhorse 702 and the carb was giving me problems, bought one on ebay slapped it on with a couple of slight modifactions for the cables it runs like new. Replacing the carb is way easier than working on the old one

I own a small engine repair shop and i am an authorized dealer for many brands - when it comes to carburetors, it is always best to spend the extra $ on the correct OEM or Original carburetor, for 2 cycle equipment it's going to be either Zama, Walbro or Ruixing (rux-ing) the cheap aftermarket carb's are NOT jetted or adjusted properly and will cause performance issues i see it every day cheap aftermarket carbs causing a no start problem, new OEM carburetor solves the problem, And if your equipment happens to be under a manufacturer warranty most are 2-5 years and you work on the equipment yourself instead of taking it to an authorized service dealer - you will void the warranty 100%. also on Echo equipment if you use anything besides an NGK spark plug you will loose up to 1,000 RPM and suffer performance issues.

Time is money don't mess about just change the carb good after market ones out there

Echo should have taken a page from Shindaiwa the company they now own. The professional (commercial) Shindaiwa trimmers made yrs ago used TK round slide carburetors vs Walboro rotary. Those round slide carburetors were built to last and have better acceleration. I have a C-27 and a s270 with a handle conversion, both have had the exact same TK carbs on them for 30 yrs and still run great. They have only been rebuilt with new gaskets and diaphragms a few times over that 30 yrs.

Just found your channel. Excellent editing! Very clear on what steps to follow visually and verbally. Subscribed. Thanks! J

Echo, well worth the repair. Those grommets are pesky. I had to remove one and reinstall to get to the fuel filter.

Excellent video!!!

I always use NGK spark plugs, cheap ones are not worth it! I recently got a new line trimmer it was running fine, then it just stopped, barely even 30min use, i replaced the spark plug with a used but good NGK it started up, no more problems.

I did this same job on the same trimmer about a month ago. It was easy to do and it runs good now. I am going to recheck the high speed adjustment. Not sure if I set it to run a little rich,

It would be nice to see a before and after as far as performance

Thanks! Was wondering where the L screw was hiding!

I advocate replacing the carburetor over rebuilding. Time to actually rebuild plus parts works out about the same as just replacing. They all need to be adjusted after either. One point to make, I have more customers "flood" their small engines by actuating the throttle trigger when attempting to start. LEAVE THE THROTTLE ALONE TILL ITS RUNNING!!!! I tell people to count to 5-10 before revving the engine. Great video! Keep them coming!

I would definately fix it myself.

I replace them. I am comfortable with adjusting carbs though. I'd suggest anyone who wants to do this start with a cheap or mid range weedeater, and work your way up to the expensive and a lot of the time more complicated stuff when you get into top end equipment.

Great video, thank you. I have a Shindaiwa T20 weed eater and have not been able to find a replacement carberator. Would you have a suggestion where I may be able to find one? I have checked Amazon and Ebay with no luck. Thank you.

Excellent job, I have had very good luck with the aftermarket carbs for the most part. If you are mechanical try to replace it. If not take it to a good shop that won't rip you off and try to sell you a new machine. Most small engines are usually repairable unless it was run with no oil. Was you throttle wide open or did it have some more throw available. Thanks for the video.

Had same problem, its cheaper to order fuel tank all set up Could not find replacement lines anywhere locally

Good video I have had the same problem older Weedwhacker messing with the carburetor and didn’t get the results ordered a new one off eBay haven’t put it on yet but I’m hoping at work as good as this one

I have a John Deere, I replaced the carburetor but I needed a coil but couldn’t find one here in the US all over seas and they wanted around 100.00 , can buy new one with a extra 100

Always adjust the low speed first. The low speed is too lean so your high speed screw has to be adjusted alot richer to compensate for the lean low speed screw. If it high idles and don't drop right to an idle it is too lean which you can hear. Once the low is set then adjust the high screw just to the point of getting rid of the miss wide open throttle. Re check the low and high adjustments a second time. Then let set overnight and see how it starts the next day cold. Might need a slight tweek again.

What are the adjustment on the high and low 2turns out on the iow. And how many on the high 2 or 3 turns. What are the adjustment

Great video..

I run a small engine shop. I can't tell you how many of these aftermarket carburetors I have installed. I tell my customers the same thing: It's a lot cheaper for me to replace this bad carburetor that it is for me to clean/rebuild the bad carburetor. Occasionally, you run in to carburetors that aren't any good. But every time that has happened, the seller is more than willing to refund/replace.

Nice job!, Thanks!

Well, for no more than a new one costs, I have just bought new ones. You can install a new one and have it running before you can take an old one apart and clean it. Years ago it was a pain in the butt to do this but now with amazon and other companies readily available its just cost effective.

I have the same model same problem, removed carb ,cleaned, adjusted. It starts fine,idles fine acceleration to full throttle snappy response problem is it boggs at mid throttle all the time ,I have to run it at full throttle to get the mowing done.exhaust outlet looks clean no black carbon build up.if spark arrestor was carbon up how would it go to full throttle with snappy response? That is the only item I didn't check.

I usually replace mine. I find it so much easier. I do keep the old carbs just in case, so it may be interesting to open them up and see if I can figure out what was wrong with them. Questions I have though, is I always try to get OEM Stihl / Zama parts and pay more for them. I just have this mistrust of Chinese knockoffs. Always wonder if this is an issue. I also wish there was a good adjustment guide out there. I kinda struggle with it.

Love your videos

Does your unit spit some gas from the exhaust? Mine does a bit and I wonder if I adjust the screw on the carb will reduce the fuel coming out from the exhaust when operating?

So the metering diagram for the fuel is already installed in the carburetor when you get it?

i just had the exact same model in for our tool tech to get running and he and i did everything in the book to get it to start but nothing and he said the carb should be replaced even though we/he rebuilt it and it had spark and was getting gas and everything was clean it just would not start

Perfect instructions except one thing. One should always tune in a Carburetor on a trimmer with the trimmer head full of line and the line bumped out to it's farthest. Other than that. Your video was excellent sir!

you should always run with the choke on the second stop for around a minute or so before you switch to the third position. then it wont bog on you like it did and i would never make adjustments until it is fully warmed up and the extra gas has burned off...which is why you let it run in choke 2.

There is usually a pocket in the housing cover that the breather cap stays.

This trimmer has a catalytic converter. You don't want the fuel mixture to be rich. That will result in more unburnt fuel in the exhaust, which will cause the catalytic converter to run hotter, and burn out prematurely. A rich fuel mixture used to be good for keeping exhaust temps down. Not any more.

I bought an aftermarket carb for my SRM2100. It didn’t work. The adjustment screws did not work properly. A new Zuma carb worked perfectly, but cost $$$$$.

Always easier to just buy the Amazon kit. I have used many of these myself. They almost always require fine tuning but they usually work pretty good. I do not EVER use the china spark plug they send. I have gotten them in many different states. lots of times the gap is completely closed. It would be easy to gap the plug but I would rather spend a few $$ on a good high quality name brand plug. I most always use NGK.

Hello, I need your help. I got older briggs and straton lawn mower out of the trash. I changed the key and cleaned it, put new oil in it. But sometimes it is hard to start and when it starts it overheats in 1 minute and runs kinda bad. It doesnt have throttle and when it runs it is on idle. ? The spring doesnt have much tension. I am really annoyed that I put a lot of time into it but it keeps beating on me. Thank you for help.
