So the surging stopped on it's own?

Question of the Day: What is the ultimate French toast topping?
Ryobi 6500 surging

The surging was my dumb ass misreading the fuel level.

Isn't the voltage determined by the rpm?
That is a good question.

Generally, but I've heard of the generators losing voltage even if it's turning, was reading when I had a surging problem and lead to me being a dumbass with fuel.
No the generator is governed at 3000 rpm to achieve the local requirement of 50khz cycle. The rotor turn around at 50 times per second. Voltage is determined by the windings in the rotor

Again
The surge on my Ryobi is caused by the choke. There is a lot of play on the choke butterfly spindle, around 1-1.5mm
The choke me genism include a vacuum servo that keep the chock e in the open position. The servo pushes the choke lever as fa as it will go against the stop on the choke lever which cause the choke spindle to tilt slightly causing it to close a few degrees. causing it to run to rich and causing the surge.
I hope I solved this by bending the stop on the choke lever slightly to reduce the amount of travel for the servo.
I run it for halve an hour and so far it seem to have worked.

Again
Almost this morning again haha. Checked the fuel before firing it up.
Does the fuel ever evaporate? Jeez. Either that or I didn't put in as much as I remember.
Thanks
Will go looking for this guy later.
The spot where the generator is right now gets too much sun at the moment for me to comfortably work there.

I thought the surging was fixed as was just low fuel?
It no longer surges really.
Just a slight miss I think that then causes, what I think, is a dip in voltage.

or like @Nemesys says, dip in frequency not voltage or maybe both?

surely flickering lights would be frequency, lower voltage would make the lights dimmer? Although, I'm thinking incandescent lightbulbs.

I'm not expert but I would assume the same thing would happen with coffee machine, lower voltage = lower speed, not sure what happens with low frequency?
Cleaned out the catch cup below the fuel cock.
Will be replacing the spark plug tonight.
Maybe do the oil change if I have time / feel like getting dirty.
Tomorrow we get hit twice a kak times so I want to be prepared.
Just bloody expensive at 3l/hour to run.
