Pull cord stuck
No matter how hard you pull starter cord won't budge or barely moves.
Bad starter recoil
Starter recoil is just jammed or actually broken. Remove and check for problems. Replace if necessary
Engine is seized
With the starter recoil removed. Remove spark plug and try to move engine manually. If it doesn't move engine is seized. It might be able to be freed with 2 stroke oil in the cylinder. If not it will have to be rebuilt or scrapped altogether.
Engine runs poorly, will not start or stops after a few seconds
Equipment not performing as it should.
No fuel or fuel that has gone bad
Before getting to excited make sure there is fuel with the proper oil and gas mixture. If it has been sitting for a long time the fuel can go bad and needs to be replaced.
Bad fuel lines
Check fuel lines for cracks and leakage. Replace if damage is found.
Dirty or clogged air filter
Engine may not be getting enough air. Remove air filter and clean with warm soapy water and let dry or replace with a new air filter.
Dirty or clogged fuel filter
Engine may not be getting enough fuel. Remove and replace fuel filter.
Bad spark plug
Engine may not be getting enough spark. Remove spark plug to check for damage and heavy carbon build up at the electrode. Replace if any of these conditions exist.
Clogged spark arrester
The spark arrester is located in the muffler and if it becomes clogged it can cause poor performance. Remove and clean with wire brush or replace it with a new spark arrester.
Bad on-off switch
On-off switch may be faulty causing the engine not to start. It can be tested with a multimeter or disconnect one of the wires from the switch. If the engine starts when it is disconnected the switch is bad and needs to be replaced.
Bad carburetor
The carburetor may not be functioning properly causing poor performance or failure to start. Jets and ports can become clogged over time. You can first try to clean the carburetor with a carburetor cleaner. If that doesn't prove effective, rebuilding or replacing the entire carburetor will be necessary

I cannot get the head off to see if there's string left in there and if it jammed. It is an auto feeder. HELP!

if you look at the side of the top cover of the trimmer head, you will see a small cutout. rotate that around until you line it up with a hole on the inside. Fit a screwdriver (Or anything metal that fits) through the cover and the hole inside to keep it from rotating,.

It depends on the type of head you are using. Bump feed and auto feed heads need to be taken apart and have line rewound into the head. It's a bit tricky to get it just right, but there are instructions online for your particular head and with practice, you'll get it. I personally prefer fixed heads and I use this burly line with wire through the middle. The stuff is amazing, you can bump right into gates and your line will survive.. Anyway, If you have one of these, it's easy! You just pull the lines out from the middle of the head towards the center with needlenose pliers and feed in new lines from the outside to the center. Be sure to leave a little extra length on the inside so they're easy to grab hold of with the pliers next time!

I have a 225 that accepts attachments, 2 years old. Commercial use. Ran great all of last summer, but now once the air temperature hits the 90's it runs terrible. I have to hold the throttle open for it to start and then it struggles to run for at least ten minutes, if at all. New spark plug, fuel filter, and air filter. I always use the echo brand oil and no methane gas.

I rebuilt the carburetor because it seemed it was running out of fuel. So I replaced the diaphragm and I'm having the same problem. I crank it and it still runs for only half a minute and dies. But will crank right back up after pumping primer bulb which also was replaced along with hoses and fuel filter. Could it be the spark arrestor??? Also replaced the spark plug.

It's the muffler I have learned my lesson along time ago. When a 2-cycle engine cranks up and won't throttle up and you have to keep trying to keep it running, and it keeps bogging down,and shutting off It's all the build up in the muffler from the use of 2-cycle oil. Here's what to do, Take your torque screwdriver and take the screws out, I believe it's two of them or look at the bottom of the muffler where the exhaust comes out , there's either three or two small screws that hold the cover on. Underneath that cover is a piece of screen that plugs up. You can either take it off and throw it away or spray it with break cleaner. Before you put it back on try cranking your weed eater without it, and there a very high chance that it will be screaming high throttle. If that doesn't work then you can take the muffler completely off, scrap around the inside of it with a small flat screw driver, and then spray break clean inside of and shake it gently and let it sit in there and then blow it out, then reinstall.

I have an srm 225 echo weed eater, I started it up and it ran for a few minutes. I started to use it and it bogged down and will not start. I replaced the carburetor, gas lines, fuel filter, air filter and spark plug with brand new parts. The weed eater started right up and did the same exact thing prior to replacing all of the parts. Any ideas!!!!

I have the 225 and i just installed the tune up kit, it will start in cold start , when i go to switch over to run it stalls out. HELP

Ok. So tried to use echo 225 weed eater after sitting for a year. It wasn’t happy. I changed the spark plug, fuel and air filters and added the 2stroke fuel from Lowe’s. I just tried taking carburetor apart and cleaning it. I got it to start and idle but soon as I give it gas it cuts out. Any thing I can try?
Mike J - Reply
I started to see gas coming out of the muffler as I tried to start it. I rebuilt the carburetor and was able to use it several time. It seemed to work well. Now I try to start it and I get gas coming out of the muffler again. That would seem to point at the carburetor again, right? What else do I need to check?

small adjusting screw under primer bulb was to tight…..did not allow proper gas/oil feed, so 1/3 turn of screw counter clock wise allowed smr 225 to run with out stoping after 20 minutes.n j kobzev……thanks to trouble guide.

I have a Echo GT-225.
The engine runs but the head will not spin? How do you troubleshoot this matter to see if it is (1) the clutch, (2) the drive shaft, or other?
Is it worth the cost of repair?

String advances without bumping head on ground...help.
Chuck Easley - Reply
Srm 225...purchased 4 months ago. First time I replaced the string. First attempt I wound it backwards and when I bumped the head the string recoiled into the head. Now after winding it in the opposite direction, the string advances without bumping the heaf on ground. Watched all the videos about string replacement snd problems associated and cannot determie the problem. I've been running string trimmers for 40 years...whats up Echo???

My SRM-210 is bogging down due to vacuum in gas tank. I've replaced the fuel filter, tank vent, hoses, carburetor, yet it still won't keep running unless I crack open the gas cap. I tested the tank vent valve and it lets air in and blew air through the hose into the tank. Air goes through. Tried drilling the orifice larger in the vent valve. Didn't help. Don't know what else to do. No obstruction in exhaust muffler. There is no spark arrestor.
Rshaw - Reply
I also removed the muffler then ran it and it still bogs down without opening the gas cap or pulling off the vent valve
