Took my newly acquired SRM210 out for a test today--it was sick, the string head would even stop turning in grass a small electric should be able to handle. I was beginning to be a little disappointed in this highly praised trimmer--took it back to the shop and opened the high speed jet a half turn--and it came alive.

I tell my wife trimmers just seem to find me--of course I'm always looking. I was in an Ace in a small town in Texas a few weeks ago--in line to pay for a few items. A man in his mid to late 70's walks up behind me with a trimmer in each hand--a new Stihl, and the above SRM210--says they cannot get parts to fix the Echo (this Ace is a Stihl dealer) so he's buying a new Stihl. The Echo is spotless--has guard and quick load head (not used commercial). I offered him $30, and I'm the proud owner of my 1st 210 (probably could have gotten it for $10).

It would run, but not very good, removed the high speed adjustment plug and still couldn't get it to run just right. I haven't had time to rebuild the carb so I put on an extra carb I had. Thought I had it ajusted right until I took it out today.

If you're running Echo's with the high speed plug still in place, you might be surprized at what a little more fuel might do for your trimmer.

And if you are running it with the low speed plug in you would be surprised what a little fuel will do in helping starting. Sadly many echo users are changing to our brands, buying carb etc....and it all can be fixed:dizzy:

Ed, I've worked on a lot of Echo's with the high speed plug, but didn't know there was a low speed plug covering up a low speed adjustment--did a search without any luck. If you feel more comfortable (based on your statement about EPA), could you pm me with more info.

Thanks

I believe this is a rotary barrel carb manufactured by Zama. The low speed adjustment cab be accessed through the top of the throttle shaft. The high speed adjustment is on the body of the carb. There is a soft plastic plug that has to be pulled to access the screw heads. A small diameter sheet metal screw can be used to pull the plug.

The 265 has 2 plugs one is straight down on the top that turns the throttle needle up and down.. the other comes in from the rear. Get a high intensity light and look into every hole you can find. By the way this zama k75 that echo is now using is a big big loser first one that I had that sometimes can't be adjusted. I have accumulated about 10 carb off 261 echo that work fine on the 265 and it can be repaired.

yes a much better answer than i gave......and if you find that the unit still bogs after you make the adjustment and after putting in a new kit and cleaning the carb ditch it and get a carb off an old 261 and you will not
be disappointd

Where are the plugs on a 230 with a Walbro barrel-style carb?

The best way to find this is by looking at a parts list for the carb--google Echo parts, pick one and pull up the parts list. Short answer--it's below the primer bulb--the mounting plate that holds the primer on has a loop, there's the plug for high speed--don't think there is one for low speed.

I see you are from San Angelo--I have a niece that lives there, she's a nurse, and her husband works for the post office.

HI, new here, found this old thread looking for info on my SRM210 would would run about 10 secs. and shut down. I got a carb kit on eBay, installed it and she started right up but lacked top end power. Adjusting the high speed screw solved that and you may be interested to know the carbs being sold on eBay have no plug, all that's needed is a jewelers screwdriver. I let it warm up, turned CW until it began to bog down and then backed it off a bit.

Thanks for the help.

The "low speed" needle is in the center of the rotor looking straight down at it. Normally ya don't touch it! HS is all ya need to mess with. ( as ya found out)

I've been running an srm210 full blast for 2 seasons now. Mine did not have plugs on ti when it was new, not sure why, but my adjustments are accessible and only require a small flat head. I've rarely had to adjust, one thing to make note of when you guys are doing the high speed adjust, make sure that when you hold it wide open the rpm's don't keep climbing and climbing, if they do, you're lean and won't last long. You want it stop revving and start 4 stroking at a certain rpm. I refer to it as 4 stroking, but it's basically that gargle you hear that you want to find.

Well said--years ago, I tuned to max rpms, didn't ruin any engines (that I know of)!! I now open up past max rpm until noticeable slow down, then lean out just a touch! RPM limiting coils sometimes makes it tougher to set high speed correctly!!

Isn it a shame how the powers that be (A.K.A. U.S.E.P.A.) have weakened our available equipment? Yes most new equipmnent is fine, and runs OK, but that are so choked up to pass the emissions standards that it's amazing what a simple carb adjustment will do. This is why I prefer well maintained aged ( hey, I'm cheap, but I rebuild everything I new spec) equipment. A trimmer from ten years ago, with a 25cc engine will ou peform a 40+cc new trimmer. In my experience anyway. I do own two new Stihl trimmers, but I don't like using them as much as some of my older but physically new spec's equipment.
