What generator do you have?

With many generators the output voltage and frequency is dependent on engine rpm. If you lower the engine rpm you will not be producing 60hz and the voltage will also drop. Those generators always run at one speed. There is no "idle down". When there is little load the engine still turns at its set rpm but it's at a low throttle setting and producing little power. As you put a load on the generator the governor will open the throttle to maintain rpm. So, no matter the load the engine always runs at full rpm. And just because it's turning at a high rpm doesn't mean it's at full throttle.
