The new brushes in your gen are making a noise because they are not bedded in on the commutator. Take a strip of very fine sandpaper ( not emery ) and carefully with your finger run it on the commutator with the engine at idle speed. You might need to do this several times. Watch your fingers. Regards, Kevin.
