I followed these instructions to a tee with my ceased Echo SRM 210. The pull cord loosened and I started it up. After 30 seconds it slowed down and shut off and was ceased up again. I can’t figure out why. I heard you mention something about the gas/oil mixture being too lean. I was using the Home Depot premix 50:1 (red can) for weeks with no problem. Then I switched to the premium 50:1 (silver can) and that’s when it ceased. However, for this fix, I emptied the silver can mix and refilled with the red can mix and it ceased again. This is frustrating. Can’t figure this out. Help please!

@@HNDSME247 mix your own fuel or run a can that has more oil in it l. 50 to 1 is incredibly lean and I believe was created just for emissions I honestly believe there's not enough oil in a 50 to 1 mix remember the first part is fuel the second part is oil so 50 parts fuel to 1 Part oil try a heavier mix 40 to 1 or heavier I wouldn't go much heavier than a 32 to one though that's getting a little heavy for "modern" 2 stroke

How much mystery oil should I put in? Lol

west wood I agree. He’s a genius. I couldn’t believe how well the Lucy’s oil and diesel mixture worked and worked quickly.

Glad I could help and I hope it works out good for you just remember to mix the oil a little heavier and it will prevent it from happening again

Thank you :-) I'm glad you enjoy the old KZfaq videos thankfully they are still here and still helping people out with things. I also swear by using 32:1 there are a few newer things that I will run 40:1 but nothing lighter than that. Thank you for leaving a comment I really appreciate it

Marc Barling awesome I'm glad I could help and thanks for sharing :)

MuffinMan Quit Hating

Gail Perry so glad I could help :-)

Your welcome! ☺️

🎨🎨🎨🎨🎨

Vince Minnillo your very welcome! :)

Were you able to get it unseized and fixed?

lmao

Sweet :-) you'll have to let me know how it turns out

Thank You so Much..I have a seized up troy bilt weedeater ! Post that video please ..

I'm sure it does but that's why I usually run a heavier oil mix in them just to keep them running as long as possible thanks for the comment

Heck yeah I'm glad I was able to help!!

But I was able to help did the process work well for you?

I left the plug in to help Force the oil past and around the rings to possibly help prevent further damage

awesome man im glad it helped you

How much power did you lose though?

50/50 or 25% diesel 75% oil depends on the oil that you use you can use 2-stroke oil and I would suggest fifty-fifty with that but would prefer ATF and I would use 25-75 with that

Thanks for the formula....I will seek out some ATF

Heck yeah! Glad I could help!!

JOHN HAUS Not necessarily. My 30+ year old Echo 302s Chainsaw seized up while I was cutting down a tree a couple years ago. I was in your thought process as well...actually kind of sad as my grandfather had it for so long. Anyhow, I set it aside bought a new chainsaw to finish the job. Was cleaning out the shed one day and pulled the old chainsaw out and was getting ready to trash it and thought for the hell of it I'd give it a try. Dang thing fired up and has been running fine ever sense. Love that saw and I'll keep it around even if it does finally die.

Awesome!! I'm happy to hear it worked for you as well :-)

Jennifer Ashbrook take the spark plug out and turn it upside down and turn it over pretty vigorously turn it over pretty quick to get as much fluid as you can and then let it sit for a while Give It 2 or 3 hours and then do that again just to get all the oils and lubricants out if it won't dry out try putting a little gasoline in there because that will help flush out what's left over

Try adjusting the carburetor to a richer mix. Running it too lean will also cause it to seize. The fuel helps to cool it

I have never tried it with gasoline I use diesel due to it being very good at penetrating kerosene works just as good.

I would not suggest using carburetor cleaner to free a stuck engine that is not a lubricant and will cause more damage

if it was being worked hard it could just simply be from not enough oil in the fuel that's why I always fix my fuel a little bit heavier than what it says for example if it says 40 to 1 which I don't know the exact mix off the top of my head but say it would be two and a half ounces of oil to 1 gallon of gas i will mix 3 ounces of oil to one of gallon gas as long as you're not belching smoke out it's totally fine. that and I stay away from the cheap 2-stroke oil I would try this method first let it soak for a while and see if you can get it to break loose. your case is a little bit harder just for the fact that it ran lean somehow and seized up due to not enough lubrication the only other way you'd be able to fix it is to get the cylinder and piston off of the bottom end and replacing them. a lot of guys say that doing this is not worth it getting it unseized and continue using it because it can be timed and only work for a short while. but the way I look at it is if I can get it to work a week a month or year more that's more use out of the machine that I would have gotten instead of just chucking it. the few that I have done personally and for customers I've had great luck with just make sure you always run a heavier mix in them.

when you say it is not worth it, what do you mean? the chainsaw can never be fixed properly or just isn't worth the cost of fixing? I was going to do (attempt) the fix myself if this doesn't work. Any idea what parts are going to be needed to fix this? I don't ever remember this seizing before, but the string from the starter would pull out sometimes like it was completely free. I would then let it go back in easily and it would catch and I could start again. This time when it came out and didn't catch, I accidentally let go of the handle and it jammed in the  housing. I could not get the starter cord to catch to start so took apart and tried turning and it would not budge. I got string and handle to catch and it would not budge. Could the string going in really fast from letting go cause this? I also noticed that plastic catch was sticking causing the string to come out with any resistance. This was first sign of something bad. I do want to fix this as it is a older one that I would like to keep. It is a Stihl 041 AV Farmboss and was only run hard for maybe 10 minutes when it got really hot. thanks for any help or suggestions as I will tear this apart and replace all that needs to if this will fix it. Give it a new rebuild sort of.  Please let me know what you think.Just to edit to say I got it unstuck. It clearly was not as bad as I thought. I was able to turn it with gloves on and it turned right away. I just couldn't turn it by the cord. I wonder if there is any way of cleaning out this chamber area where you are putting this liquid to lay on the piston? Mine is located on the bottom back side and if I pour anything in there, it looks like a pretty big chamber. Should I fill this chamber up with this mixture and just let it set overnight than empty it out? Might clean it out and let it spin a lot easier.

its called the starter cup and it's pretty easy to remove when the cylinder is frozen solid like this one was if you're trying to remove it when the cylinder moves freely then you're going to have to stop the cylinder in some way to get that piece off

+Larry P S Could be a severely clogged spark arrestor.

If you are going to cycle the piston without a spark plug make sure the opening for the plug is cleaned up so nothing ends up falling inside. I would also consider scraping all carbon build up off the exhaust port since it can end up breaking off and scoring the piston when its not running typically during transportation. Just make sure you know the correct way to do this positioning the piston at the top of its cycle exposing the piston skirt only. I sometimes like to just pull the head off the cylinder when doing this to make sure theres no lip inside the cylinder of carbon anyways. I also replace all the gaskets when doing this and check the flywheel and the opposite side of the crankshaft making sure there is no play there. If there is its time for new crankshaft bearings and oiler seals. I would have to use a crankcase splitter tool to get it apart most times and the correct flywheel puller too. You may also want to readjust the L screw on the carb to make sure its not running to lean while attempting unseizing the top and if your removing the cylinder pour a little 2 stroke oil into the crankcase since its already open an new gaskets for the muffler, cylinder, crankcase(assuming your splitting it apart), and carburetor side. I sometimes use a butane torch to burn the muffler clean when its to invasive to open up and scrub clean with steal wool. If you think there is any chance you might not remember how to put it back together take pictures of every step you do disassembling to use as a guide for putting back together. Also Ereplacementparts.com often has diagrams of your item making it easier to figure out what goes back where.

RetardPwnage I am one of the few that actually message back :-) so if you can give me more information were you using it and it started to seize up and you shut it off? It sounds like it since you said it can still turn over but it's just really hard to move I would put a mixture of diesel and Marvel if you can get any. Put about half an ounce into the cylinder and let it soak for a day or two and then change the oil on the trimmer with four stroke oil and start it up and see what it gives you the four stroke engines are a little more complicated once those seize they're harder to unseize there's a lot more moving parts

Awesome, thanks for replying! I just haven't used it in months. Decided to dust it off and the cord just wont pull. Took off the engine cover, the coil mechanism came off and the cord mechanism (when free of the engine) pulls cleanly, the part of the engine you used vice grips on turns similarly on mine just with a whole lotta force! I will grab some diesel and order some marvel online and let it soak for a day or two, failing that I'll head down to my local mower mechanic! Cheers

Hopefully it works well on yours as well just be sure to run extra oil for the rest of its life to make sure it doesn't happen again. Somewhere between 32 to 1 and 40 to 1 mix I don't get any less than 40 to one in all my equipment though even though they call for 50 to 1 or less I just think that's way too little oil for a two-stroke engine 🤷🏼‍♂️

True that!

Heck yeah! Not a problem :-) I'm glad I was able to help
