I have a 5.5kVA petrol generator for sale. It starts and runs, but doesn't produce electricity. I've had it for about 6 years and used it as often as I had to. I am going to go solar and diesel, so I don't need this generator anymore, and don't really have the time to have it repaired.
It's made by Powermax, and I don't know if that's good or bad, but apart from it not making electricity now, I haven't had any other issues with it.
It's able to power my entire house, apart from running the geyser and stove simultaneously.
