How Do I Fix a Surging Engine Video (Lawn mowers, tillers, pressure washers etc.) - YouTube
Oldpath05: have you been using ethanol free fuel in the mower up till now?
never owned an echo, i have been blessed with good luck out of my stihl stuff
I watched that one but for me it;s hard to fix something/carb when it's not the same carbuerator, thefore I watched this video and found it more helpful because it is exactly what I have>>>>>>> Nikki 2bbl Rebuild Part 1 - YouTube
Well I mowed my grass and weeds this afternoon, the mower did start right up but it went right into surge mode but after two hours of mowing and almost done it started to run smooth again, parked it in the garage and let it run for a few minutes and it ran nice, now if it will just stay that way........
I bought this Echo brush/grass cutter two years ago, it sat or hung with last years gas in it plus a little Star tron in it, ;ast month at first start up it took 4 pulls and today it took 2 pulls, idles great no surging, yet. This Echo cutter has all the power I need, my only gripe is it's made for people 5'-8" - 6' tall, I'm 5-5 and have my harness choked up as far as it can go just so to be comfortable for me to use, be nice if the saw head could have a angle adjustment.

Pretty much sounds like a clogged or partially clogged main jet.. Had that problem with one of my mowers, cleaned it out and worked great.. for a while, then it started surging again. took it apart again and re-cleaned that jet and haven't had that problem for a while. it got something in the fuel system that kept catching in that jet..
