that generator will always run at 3600 RPM. 60hz
if the freq is correct the speed is correct
it will get louder and use more fuel with a load
but it is still the same speed plus or minus 2hz / 120rpm

if it won't carry the load
A: the load is too big
B: the generator is failing

open the end of the generator head and check the field brushes on the slip rings
