You always make these repairs so easy to understand. You make me look like a small engine expert to my family. Thank you.

I really like how detailed your video was. But in my opinion, if you’re only aiming for the piston ring, just take off spark plug wire, the top cover, the intake (leave intake off to the side with wires and hoses still connected) and you should be able to pull the head right off with the coil and exhaust still on. Switch out the ring, lube, and reverse. No need to separate the engine from the assembly. But that’s just how I do it.

7:41 it’s like a baby piston got born when it slid out lol

While a well made and thorough video. Aside from draining all the fuel for safety and less mess, I found you only need to remove the plastic shield, unscrew the carb and leave it hanging. Pop off the spark plug wire, then the 2 screws to remove the cylinder to have access to the piston. I don't even remove the muffler or spark plug.

Thank you so much for such a detailed explanation. I followed your steps nd was able to repair my brush cutter by muself...luckily, parts were available at my local store. God bless you guys 😊

That lil piston is so cute man 🥺

What a great video. Clear and professional. Step by step. Thanks!

Replacing a piston ring on an Echo weedeater involves several steps. Keep in mind that it's a detailed process, and if you're not comfortable with small engine repair, it's advisable to seek professional help. Here's a general guide: Safety first: Ensure the weedeater is turned off, and disconnect the spark plug to prevent accidental starts. Disassembly: Remove the engine cover, spark plug, and muffler. This will give you access to the cylinder. Remove the cylinder: Loosen and remove the bolts securing the cylinder to the engine. Gently lift the cylinder away, exposing the piston. Remove the old piston ring: Carefully take out the old piston ring. You may need to use a small pick or screwdriver to help lift it out. Clean the piston and cylinder: Wipe the piston and cylinder clean from any debris or carbon buildup. Make sure both surfaces are smooth. Install the new piston ring: Carefully slide the new piston ring onto the piston. Pay attention to the orientation specified by the manufacturer. Check and lubricate: Ensure all parts are securely fastened. Add a small amount of 2-stroke engine oil to the cylinder and piston to lubricate them. Reassemble: Put the cylinder back in place and secure it with the bolts. Reattach the engine cover, spark plug, and muffler. Test: Reconnect the spark plug, start the weedeater, and check for proper operation. Listen for any unusual sounds or vibrations. If you're unsure or uncomfortable with any step, it's recommended to consult the user manual for your specific model or seek assistance from a professional technician.

Thanks. Excellent and clear instruction video. There is no need to torque the cylinder screws down? Subscribed.

what is the ohm spec tolerance of the coil? What is the piston ring tolerance up to the point where crank pulse is too weak to push and pull fuel from the carb? And, will not replacing the head gasket , if it has visible wear just at the bolt holes, after pulling the head lower the crank pressure such that hard starting or no starting occurs?

So much easier than the Troy bilt I worked on. Had to pretty much disassemble the entire thing to fix the pull rope. I just use it for the pole saw and have an echo trimmer. I’ll be buying another echo when the time comes. Or going electric.

You forget to clean the piston.. I'm always clean the piston head and groove.. Next time use a piston groove cleaner... And clean the cylinder as well.. Good job 👍

Where can I get a gasket for 125l husqvarna weedeater not carb gasket

Thank so much for your nice details video

Thank you so so much I've been trying to take the clutch off for too long now

I am restoring a old weedeater right now and the engine is actually in really good shape, i thought about putting a new set of rings, when i went to price them they wanted 35 dollars for them,lol, not gonna happen, they should be 15 dollars for the pair if that, im trying to find alternative or maybe a different brand, no rush at all on it,just a little fun project.

Nicely done, sir. (I just wish that you'd started the engine at the end of the video.)

Well done and not a waste of time Thank You’ll

Why the hell would you remove the flywheel and starter pawl to change a piston ring? On that note, if you're not changing the cylinder, you don't even need to take anything off. Just undo the two head bolts and remove everything at once. Also you didn't torque the head bolts upon reassembly nor mention that this needs to be done. Seems like a vital piece of information that was missed. For anyone who wants to know, Echo's spec for these bolts are 60-85in/lb.

Is it a workable solution to just do the ring without changing the piston head? Struggling to find our Kawasaki piston…

I have problem with my srm 210 a lot of smoke comes out changing the ring will solve the problem thanks for. the video

installed new ring and cylinder gasket and still only pulls 45psi for pas 225. the ring takes a bit of effort to seat, about like whats in the video... but maybe the upper portion of head is egged?

It must be nice to be able to remain so called during this process. I'd be throwing wrenches and sockets at walls probably

Need help with an issue inhave with my husqvarna trimmer 128ld. I changed the cylinder and piston, i also calibrate the magnets in the flywheel, I have a conpression of 100psi, new spark plug(sparks good), new carb, new fuel lines. It wont start. Any ideas?

*let's get started*

Great video !!!! Thank you 😎

Can you please give me the number off the piston ring so I can get one and thanks 👍 for your help

At first I ws scared to open the piston section of the engine ... as i needed to change the seal, replace gaskets, clean the pistonhead and engine head where spark plug sits... my brush cutter lost its compression and switched off itself. But now its running like new 😊😊

Either I missed it or , you didn't clean the piston gap where the new ring goes ? Was it already clean ? No carbon fouling ? Why take it all apart if your not going to replace the crankcase seals ? You can gap the magneto with the crankcase still bolted to the clutch cover and you didn't check yhe exhaust screen for carbon fouling ? Not being a smart butt or anything just curious ? Also why remove the carburetor at all ?

Very clear and helpful. Thanks

Thanks! I wonder one thing about the piston-ring. Does it have to be loosen 100% or 80% to work properly? Is it also a scratch-mark where on the piston where the ring can not move pass left or right of the scratch-mark with the opening of the piston ring, does it stop circulate at the piston at the scratch-mark? How can you see if the piston-ring is bad or wornout?

Can u tell me what piston rings I need for a srm-210 echo. Or the cheapest replacement for the machine

Does anyone know how much will it cost to put a new cylinder and piston kit on my echo 225 weed eater...parts n labor .. thank you .. Ezequiel

What size ur piston and piston ring

Nice work m8

You did show how to remove the broken part of the shaft.

possible update trimmer echo 16 cc cilinder to 22 cc or 30 cc ??

Will an srm 225 piston fit in an srm 210?

sowhat happens when the piston will notline upand go backin chamber correctly without forcing it. Im upthe creek

I have one I want to fix it

Thanks for sharing. Look easy take all apart. I won’t be able to put everything back. I leave it to the professional OR buy a new one cheaper than get it repair. Lol.

I followed all the steps and it still won't start. Getting good spark, used a in line spark tester. My compression gauge is reading 30, but I don't think it is correct. I put my finger over the spark plug hole and felt like it was enough to push my finger off. I tried starter fluid also and couldn't get it to start. Could a plugged exhaust cause it not to start? I may need to take it apart and see if I assembled it wrong. I am just worried about putting to much money into it , because it will be cheaper to replace. It is an Echo SRM-210 over 10 years old. Any suggestions?

Good presentation 😊👍

You don't have to detach the engine from the frame only for a piston ring replacement. With the plier that's how you break a clutch and a recoil paul ratchet. There's pistons stops and and tools to do that without risk. This is a job that takes just 15 min.

hola soy omar de argentina kisiera q me ayuden a ajustar la cadena d la motocierra por q lo ajusto qeda vien ajustada y loego lo pogo a travajar se desajusta toda o se ajusta demaciado q me kita potencia ala makina prove d todas manera y n me da resultado si se puede m esplica en español gracias amigo

I have a Kawasaki brush cutter and I replaced the piston and rings and did not have to remove the clutch or the cover why was that necessary in this video

Thank You.

need help got a Titan-TTL530GBC it as a spark compression is good and replaced the carb fuel lines but it will not fire up only thing i can see if when you look through exhaust side piston as scratch's on it please help thanks

Good morning good morning sir help how to fix corporate

whats going on when you feel the piston hitting the spark plug . Remove the spark plug and it then it pull smooth this happen after cleaning the carb after it would only run in full choke??

Good video!

You don't have to take everything apart to do the job.

I think I’ll just buy a new weed eater. Thanks.

Good vid, keep it up

Replacing the piston ring makes a great video but my experience is that the trimmer still will not run. Whatever destroyed the first piston ring also destroyed the piston and the cylinder and replacing the ring will not fix the problem.. Give the trimmer a big heave and get a new one.

Great video, very detailed. Thanks!

Excellent video, j have that exact trimmer, lol. Not a repair for the faint of heart though. Just curious, what type of screwdrivers did you use. I know the screws are not normal Philips. Thanks!

I think it we're supposed to go straight to the cylinder

Why did you put a new flywheel on it?

Is the carb isolator there to prevent the carburetor from getting too hot?

Damn I might as well buy a new edger my goodness

My flywheel doesn’t pop off like that

How much does torque spec matter with these small engines?

Awesome video! What size Torx are they?

Can someone please give some advice. I replaced the piston but when I put the screws back in to the case the piston doesn't move anymore. It only happens once I tighten one of the screws. What am I doing wrong and how can I fix it

How do you source gaskets?

How the fuck can you put the cylinder back with so ease and I'm fucking struggling here about to throw the whole damn thing to the floor because the damn cylinder doesn't want to go in

Take a shot every time he says “now remove”

Echo best 😂

At this point just buy a new trimmer 😂

Most of that is unnecessary for just pistion and head removal.

You forget to add some oil in the crankshaft chamber 😏

Why is it always so easy for someone on KZfaq to do things? But when I go to try to do it exactly the way you show it in the video it ain't happening dog

15:32 Deez nuts

The WWS special

roshan

simple no way....I would not try doing this...I'd rather buy a new one lol

Yeah, ummmm...I dunno about using a razor blade to scrape _ANY_ gasket sealing surface. Being too aggressive or having a slip-up could easily scratch the soft aluminum and pretty much render the entire repair effort pointless. Bad crankcase seals on a two-stroke are a _bitch_ to diagnose. Better to use a plastic scraper...

My shindaiwa t242 weed whip has 2 piston rings one right under the other separated by an 1/8"gap

Deez nutz 😂
