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.
@@glennfarrar3107 I used a piece of plastic from a bleach container. Cut a strip, wrapped it around the ring, pulled tight by tabs I made. Just bending the ends of the plastic at approximately 90 degrees. Then you can keep pressure on it so it slides in. Oil it up real good. I like assembly lube.
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 😊
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.
Confirm your finding! I have to admit Echo is very well design and simple for maintenance. No wonder they sell millions of these trimmer around the world!
I didn't even remove the carb. Carb and exhaust still attached. The plug I pulled just so that I can test for resistance in the rotating assembly, make sure the bearings are good and I lubed it sufficiently.
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 👍

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.
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.
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.
Every one always wants the cheapest...reaserch the part based off your manual part numbers" sure you don't want to over spend on parts"...but you don't want to buy a part that could brake inside the head" and cause damage" That piston ring is the life of the 25.4cc Engine..Then the carburetor" if you don't have compression or lack there of" The until want run correctly" all because of the best known word to man ( Cheap )...Your Oil/ lubrication mix with 89% octane to produce your 50 to 1 Ratio" The screen inside the exhaust port" The gasket / Filter inside the housing for the carburetor" ..I know a few people that use the Pass/ SHC 266 For the last 10/15 yrs...And that trimmer sounds like a Yamaha dirt bike...Cool! ***🏆***
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?
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?
Hi Zeke, thanks for your question. The size of Torx screw may differ on individual leaf blowers. If you send us your model number, I may be able to help you find the right size!
@Joe Brone I got a T-27 bit and it won't even go into the T screw head. If your T-27 is worn, it may go into the T-25 screwhead. It may also bind up as the worn angle meets up with the splines in the T-25 screwhead. That may be why your T-27 fits a bit better.
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?
If all of your electrical components check out okay. It sounds like you may have fuel delivery problems. This would mean that you would either have to rebuild the carburetor, tune it up or replace it. We do have videos on these repairs on our TH-cam channel. Here are the links to them:th-cam.com/video/RfzzTilqwo0/w-d-xo.html th-cam.com/video/mnrVRaJgBbA/w-d-xo.html
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 ?
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??
Rebuilding the carburetor shouldn't have caused any of your problem. I've seen this happen when the repair person replaced the plug and the new plug has a longer electrode or if the needle valve is stuck open and fills the cylinder with gas.
Fix.com I know this is old but I have a trimmer that did what you said. Filled with gas and locked up. Right after I put a cheap replacement carb on. Is it better to rebuild the carbs? Can’t remember but believe I robbed a different carb off another one I had lying around afterwards and it runs fine. Would replacing piston ring get some power back possibly?
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 😊😊
Hi Lee, the technician did not replace the flywheel. He did however reset the gap between the ignition module and the flywheel magnets. This should be done when you remove the flywheel.
It was a cut taken from an actual flywheel replacement video. When he got to the part of installing the flywheel, they used a cut from a video of him actually replacing the flywheel. Go to 5:45 of this video and you'll see it is the exact same clip m.th-cam.com/video/2XxOJbh8XRQ/w-d-xo.html

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.
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
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.
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
I'm guessing the screws your talking about are the ones that that hold the Head onto the crankcase. Right? If so, does the piston seem bound up or like it's hitting the top of the Head. if it is bound up does tightening both screws equally help the issue?
Fix.com Fix.com I already thought about trying that but no combination seems to help. I can screw one really tight and no problem but the other makes the piston not move once it is barely tight. If I keep both screws loose the piston makes a knocking sound on every 2nd stroke and that only happens when the spark plug is fully screwed in. If the spark plug is unscrewed it doesn't knock. The gasket is in good shape so I don't know what can fix it.
If the piston and rod are the same lengths as the old one I wouldn't think that to be the problem. There's certainly and issue with the head room for the piston whether it's the rod and piston length or the length of the spark plug. You say once the plug is removed the knocking noise stops. Does the motor turn freely with the plug removed? If so I wonder if the length of the plug is to long causing it to hit the piston. Did the plug get replaced recently?
I found the problem. When i full secured the piston case the magneto would get pressed against the plastic spinning part causing it not to turn. Once I adjusted the magneto hiegth the noise stopped and it works now. The only problem is when I give it throttle its almost like its flooding itself and gas is getting ejected from the exhaust. I think somehow too much gas is getting into the space where combustion happens. It also shakes excessively.

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
It's actually not that difficult to replace. The ring can't be more than $10 and a new trimmer cost $200. With enough time and patience it is a doable repair. Of course you need to have the right tools to do this job.
Why is it always so easy for someone on TH-cam 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
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...
You always make these repairs so easy to understand. You make me look like a small engine expert to my family. Thank you.

It's actually not that difficult to replace. The ring can't be more than $10 and a new trimmer cost $200. With enough time and patience it is a doable repair. Of course you need to have the right tools to do this job.
My flywheel doesn’t pop off like that
You forget to add some oil in the crankshaft chamber 😏
Not needed it'll get oil from the gas/oil mix
I too like to use assembly lube. Even in a 2 stroke. Not a lot, just a thin coat.
Echo best 😂
Beats steal no bs valves to adjust and there lighter
Most of that is unnecessary for just pistion and head removal.
true
Why is it always so easy for someone on TH-cam 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

the piston head does NOT slide that easy over the piston ring. That is ridiculous
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...
