I just bought this because our power is out. I put the wheels on oil and gas and it fired up and it’s powering my house. That’s about all I can say at this point. It’s working as it should.
I live at 4,000 ft and need to change the carburetor jet. It's not simple but the video instructions are good. My only reason for removing a star is that the operators manual is not clear on when you need to unbond the neutral from the frame (consult a qualified electrician is not helpful) and doesn't give you a sticker to indicate this, if you do so. My generator ties into a Backup Power Transfer Meter, so yes, they recommended unbonding the neutral.
