Just Ordered A New Weed Whacker

[Mackelroy]

Yes i have the echo, I immediately modified it for best performance.

The carb is plugged, you only need to access the high flow adjustment screw, as the idle is fine. Ditch the exhaust screen too.

there are videos on the modification out there.

Yes I like it , but never used in stock config

If you ordered it from Home Depot, it's going to need the air to fuel ratio adjusted. The receiving area of Home Depot is littered with returned Echo string trimmers because the average consumer has no clue how to set air/fuel ratio.

Look on YT for the procedure - if I remember correctly you have to pull out a brass plug to get access to the screw. It makes a big difference in how the engine runs, highly recommended.

Another update: the air/fuel ratio is non-adjustable on this carburetor; you have to remove a limiter cap so that means buying a special tool. They can possibly be removed by yanking w/pliers but not sure. It runs fine, so no adjustment needed at this time. Also, the motor has "assembled in USA" if that matters to anyone else.

Here is the procedure for adjusting the carb. fuel mixture on an ECHO 225.

The tool is $7.19 on Amazon.

What does this have to do with the depot? I got my srm2620 from the home depot right off the shelf but my edger shipped straight from echo to me via home depot

Here's the carburetor for the SRM-225.

In this drawing, the low speed mixture needle is not shown, but I have the passageway marked by the red arrow.
Reference #11 is the plastic plug to be removed for gaining access to the low speed mixture needle.
The special tool (Echo 91157) has a threaded tip for screwing into the plastic plug.

In this drawing, the 1st red arrow points to where the high speed mixture needle.
The 2nd red arrow points to the opening where you insert your screwdriver for accessing the high speed mixture needle.

Those exhaust screens are an abomination!
