Question about Buffalo Tools 4,000 Watt 6.5 Hp Portable Generator #GEN4065
The floats in the carb are sticking! That is why it is overflowing. You can adjust the carb idle screw and needle height

This seem issue with the engine governor which should maintain the voltage at the rated speed. The generator should already have a voltage regulator in the control circuit.
The governor is designed to automatically speed up the generator, or slow it down, depending on load demand. Get the governor checked by a qualified technician and if you know how to do it be careful with the test leads and don't get shocked.

With air filter off see if the carb is loose at all. if it is then it is sucking air. tighten it and it shoild be fine.
If it is tight there should be a screw at the bottom of the float bowl. open it and let about a half cup of fuel drain. Try it again. If it is ok then you had water in the fuel.
If it still runs rough there are at least one screw on the carbs body (not the idle adjust) turn it all yhe way in and then back it out 1 1/2 turns. Try adjusting the roughness by turning the screw with the engine running.
If still no joy then see if there is an in line filter change it. It may be clogged.Also try loosening the fuel tank cap. It may be causing a vacuume that is not letting enough fuel get to the carb.
If these fail then remove the carb and kit it. Blow out all passeges with some carb cleaner. Then blow it dry with compressed air prior to reassembly.
