Parents gave me a little curved shaft homelite trimmer in 1999 for my birthday. Thing was around $69 and I still have it today. I've done a few things to it including a new piston because it started losing compression. I've used the hell out of it through the years. It's real easy to just toss something and go buy a new one which is what most people that use these things for homeowner use do. There is huge satisfaction in taking what you have or what is seen by someone else as garbage and making it run. Same satisfaction applies to working on guns.
My parents taught me not to do dumb things, such as not pitting oil in 2-stroke fuel. and buying parts that will total more than the cost of an entire new unit. I need the spool, a pull starter, a fuel tank grommet, and a carb overhaul kit for my POS Toro power head. I am tired of screwing with it everytime I go to use it. Been using a drill motor to start it
@@Freekniggers Small machinery is very fickle,lawnmowers,weedeaters, tillers, snowblowers, you name it,they require a lot of maintenance which 90% of people dont want to or forget to do,the first thing they do wrong is use ethanol in them, thats a bad mistake. Last year i overhauled my mower and here i am preaching about maintenance and i forgot to oil my air filter and one summer of mowing burned the engine up, when i took the carb apart here recently it was full of dirt and of course the engine was shot,big gouge on piston and cylinder. To use your expression, "they are junk", they are ALL like that, thats why most push mowers are a buck and half because they know most people are not going to maintain them, 2 summers and in the trash they go, then the new models come out with whatever is trendy at the moment,cupholders,usb ports,lol but it still the same delicate machine.
THANKS Brian!! We like doing projects like this one where we can help people save money on a repair and show that it's not as complicated as people might think to work on some of these 2 cycle engines.
*sarcastic* Thank you for showing how you put the casing in the cylinder back, really helpful Here I am trying to put the cylinder back and boom, you edit and skip that part jumping to the casing already in place. Thank you
When you're stuck inside in a shop all day long it's nice to be able to work outside on some small jobs when ya can. What part were you wanting to see?
@@EshlemaniaTV all.. removal of piston and push back on or in? Since I didn't see it, I can't explain it correct . Newbie but I only need to see it and do it .
Great job... just finished rebuilding mine. Not a new cylinder or piston but gaskets and fuel lines etc.. looked very familiar. Was shocked to find out a new coil is $80!
Between this video and Andrew Camarata's video of him working on his chainsaws, I am much more comfortable doing these types of repairs & replacements.
I'm glad they used gas.. cuz I never knew what the whole gas to oil ratio was meant for! so now I know to create a smooth motion for the piston. instead of just dryness makes it so it's just a bit smooth and lubed. otherwise it's just piston rubbing (friction) against the metal its housed in essentially. good video should be a tutorial for households who use lawn equipment. I have a pas 225 trimmer myself just got a new carb and gas lines today that's why I'm soaking up these videos gonna spend some time on it over the weekend it shuld b ez. Thanks man keep smashing some videos our way there super good!
These cylinders have a bit of a taper at the bottom so all I had to do was get the piston started and then push the piston ring into the groove with my fingertips as the piston slid into the cylinder.
I can’t find it anywhere but what’s to low of compression for the srm225. Mines running for a bit then shuts off and won’t fire back up for awhile. I tested compression and it says 60psi. That seems low
60 PSI is WAYYYYYYY too low. Most people will say that about 100 PSI is the low limit for the majority of 2 stroke equipment, but I usually look for at least 120 - 125 PSI.
Captions with torx size and nut size would be helpful. Government should mandate every gas tank have mixture in two languages on the side of the gas tank easy to do. EPA is always concerned about emissions. That would go a long way to keep it running correctly. just got a new Husqvarna 130l The instruction book says 2 1/2 ounces to 1 gallon of gasoline. But it ships with 2.6 ounces go figure. Every one of my two cycle yard tools, chainsaw, pole, trimmer, weed trimmer, etc. have A slightly different mixture, not critical, but if you want to control the emissions, it should be the same as they tested it.
I know you made this video some years ago, but I have a question. If there is scarring on the piston and/or cylinder wall will that cause compression problems. I have the same model: it starts, it revs, and can run the entire time I hold the throttle open. But as soon as I release the throttle it dies. I pulled the cylinder off and there is scarring on the piston. Will changing the piston fix the issue of not idling
I just did my 1st ever port job on one of these motors. Honestly not much difference but it was fun super fun. I also cut a chunk of the piston off on the intake side (window) just to see if it would still run. Damm thing still runs as good as ever lol
Every newer echo ive ever used or known anyone else to use has the same problems. The fuel doesnt flow properly at any angle other than level. The engines lose conpression after around a year if not sooner. The carburetor needs adjustment after a few months and you have to dig out a brass plug they put over the adjustment screw to cost you more money and time. And you might as well pull out the spark arrestor screen soon as you get it.
I have not experienced a single one of those problems with my echo stuff. My first echo was a 355T chainsaw I got as a "throw away" until I could get the "good" (more expensive) stihl top handle. What ended up happening is a lot more echo equipment coming home. That saw sees constant use. Runs like a champ 3 years later. No problems with the brush cutters or blowers either.
had 3 echo trimmers used the 1st for 9 years some one wanted it worse than me so i gave it to them its still running 10 yrs later the second died after 11yrs for incorrect oil mix not my fault third is still rolling along on its 7th year and none have had any card rebuilds or adjustments so i would say if maintained the echo is a goooood product in the string trimmer area and i have 1 saw and backpack blower and the only prob ive had was hardening of the fuel lines and replacing them they are good to go love my stihl saws but the echo weed eaters have outlived all the stihl string trimmers and their self feed heads are excellent
Am I seeing things... or am I the only one who noticed that the base gasket has just has three holes to let the air fuel mixture into the transfer ports instead of a cutout the size of the crankcase and transfer ports.....
Retail price is $239.99 for an SRM-225i (Model in video). Parts to fix this trimmer cost me about $75. So that's just over 1/3 of the price of a new SRM-225i. If this was a GT225 that retails for $149.99, then yeah just buy a new one.
40:1 or go home. Rather have a lil more oil than 50:1 as much as i beat on my srm-225. Midswell do a little porting with the cylinder off. Im surprised it didnt eat the con rod and crank with no oil. I always cover the cylinder and piston in 2 stroke oil on new rebuilds. That hole on the insulator is the pulse port.. fuck that up it ant gonna run for long. Wot on the first start isnt smart.. heat cycles and varied rpm for the first tank.
Be me: start having issues with SRM 225 spitting gas out the muffler while trying to start weed eater. Decide to start tackling shit head on. Start removing shit-ton of bolts, taking off fuel lines (which one went where again?...meh, I'll figure it out later). Remove old carburetor, replace with new one (thinking this is part of the issue)...remove cylinder housing, clean it thoroughly...clean piston and piston ring with wire brush thoroughly...clean screen on muffler thoroughly, put it all back together: won't start. Start taking everything apart, backtracking all potentials "oopsies" thinking I didn't put something back together right. Take off gas tank, empty it, thoroughly clean it, fill it with brand new gas mixture, put everything back together a second time: NOTHING. Remove new carburetor, replace old one. NOTHING. RAGE FIT THIS PIECE OF F*#@ING SHIT! F it, I'll buy a new one in the morning. One more thing before I do: I'll watch THIS video. 13:22 comes along regarding fuel lines and realize: I REVERSED THE EFFING FUEL LINES TO THE CARB. Go outside (10 at night) switch fuel lines, starts up like magic. FML...thumbs up and thank you (for making me realize I'm retarded)
Adrian Gonzalez izback the recoil Is much easier to pull than the average trimmer. There is the i30 which is the standard recoil then the i75 which is 75 percent easier to pull than a standard recoil.

Attempting my first small engine cylinder replacement and appreciate this video guidance
These engines are a blast to work on. i literally replaced rings on one of these during a smoke break at work. Boss couldn't believe it lol.
There's not a whole lot to them. And everything is pretty easy to get to on them.
@@EshlemaniaTV yeah too bad they are junk.

replaced rings during a smoke break. That could be manipulated in many ways. What was smoking? Did they break their habit?
Don't smoke! Keep fixing small engines, though🙂
Thanks for pointing out the machine screw on one side, hope I remember that when I do a rebuild.
Great job , very clean work, well done.
You guys sure do a great job,keep up the good work guys.

Since there is only 1 piston ring it should be possible to use a hose clamp to compress the ring.
Yeah, he skipped several steps. Coil set up
Another one-handed RUclips video. Everything I wanted to see was skipped over. I loved your professional workbench.

Great job... just finished rebuilding mine. Not a new cylinder or piston but gaskets and fuel lines etc.. looked very familiar. Was shocked to find out a new coil is $80!
Echo ignition coils have a limited lifetime warranty on them. Always good to ask the dealer about that when you have an ignition module issue.
Awesome video. What amazes me is you didn’t even get your hands dirty lol.
This was a fairly new machine, so not many dirty parts on it.
Great video! Thanks
Wow brother amazing explanation you help so much
Great video, very detailed. would like to see a similar job on a Shindiawa C350. thanks watching from Trinidad

Thanks for the great feedback. The PAS-225 uses this same engine. The PAS-225 is a really popular model in our area.
Great video
Thanks!
awesome video :)
THANKS Chris!
Should oil the piston before installing
Damn straight. Any 2 stroke rebuild its the bible to coat everything in 2 cycle oil.
The echo 225 line of equipment the average compression on them that I seen is 80psi and they run great. As long as the piston isn't scoured.
I have the same Milwaukee impact driver I use it for my small engines very good tool make sure you use quality Allen sockets
Good call!
Nice!
Thanks!
Same trimmer I have. Got it for free.
Nice video, but it would have been nice to see how the piston was inserted into the cylinder head
These cylinders have a bit of a taper at the bottom so all I had to do was get the piston started and then push the piston ring into the groove with my fingertips as the piston slid into the cylinder.
Does the clutch just twist off (unscrew).? Counter clockwise? Dont want to break it lol
I can’t find it anywhere but what’s to low of compression for the srm225. Mines running for a bit then shuts off and won’t fire back up for awhile. I tested compression and it says 60psi. That seems low
60 PSI is WAYYYYYYY too low. Most people will say that about 100 PSI is the low limit for the majority of 2 stroke equipment, but I usually look for at least 120 - 125 PSI.
Could you give part numbers for the cylinder and piston/ring?
I saw a rebuild kit with whole carburetor for $16 . For this trimmer.
eBay man
The Echo SRM-225 is a big seller for us
The jug slug and ring is done man that an expensive repair.

Scoring will DEFINITELY affect compression..
225i easy start recoil
You don't have to inspect the crank or replace the crank bearings? 🤔
Not unless the ball bearings have seized
For anyone that knows, what do the different codes after the 225 mean?
How about doing a video on the typical Echo bogs down and dies.
You didn’t have to thread tap the new cylinder for the carburetor..?
Nope
I want to put a bigger piston and port and polish one and see what it would do
I just did my 1st ever port job on one of these motors. Honestly not much difference but it was fun super fun. I also cut a chunk of the piston off on the intake side (window) just to see if it would still run. Damm thing still runs as good as ever lol
Air filter looks brad new.
fun fact: any gas engine has lower compression at idle when intake vacuum is high

Yes we did.

That machine looks like it was rained on. Was it used commercially?
Do you piston part number?
Nice. Where can i order the piston or parts thanks
Any authorized Echo dealer, or PartsTree.com
Wouldn’t it be easier if you removed the the shaft first ?
Where did u get the new piston
Local Echo equipment dealer
@@EshlemaniaTV Thx
You can almost buy a whole new trimmer for the price of the cylindr and piston.
What's the fun in that?
