Yamaha ef2800i surging
I am getting a little surge from my Yamaha when in eco mode. I remember the Honda eu2000 doing this and it was the carb. The Honda is so popular there is a ton of info, the yam ef2800i doesn't seem so...

99% of all small engine surge problems are dirt/debris typically in the idle circuit. If you turn off the automatic throttle control and it is still surging, this is highly likely your problem.
Fuel additives MIGHT clear it, but more likely than not the carburetor will have to come off in order to clear all passages. Use a single wire from a steel wire brush.
