The carburetor needs to be rebuilt - the float valve is stuck open.

It generally has a long rotor through bolt accessibile from the generator end, this forces the generator rotor onto a tapered shaft on the engine. Once removed the through bolt slide a long bar ion the hole and screw the bolt back in, that will force it off the taper

Engine speed is too high, and/or excitation capacitor is bad

Take the through bolt out of the end of the alternator / rotor shaft. it is a long bolt. The shaft from the engine is tapered and unlikely to just pop off. Find a bolt that will screw into the end of the rotor shaft (hardend) find a metal bar that will slide into the rotor long enough so the bolt tightens down on the bar, it will pop the alternator off the tapered shaft
