I have a Poerback GB5000 generator for sale. I picked this up at an auction recently. It pulls freely, but doesn't run. I did get it to start after 10-20 pulls. It needs a good cleaning and at least a tune up. I'm asking $60 to get my money back since I don't feel like working on the generator. If I don't get anyone fairly quickly I will work on it myself and if I get it running good the price goes up to $200. This generator cost between $600-$800 when it was new. It has a beefy 10hp motor on it and is built well. Take a good look at the pictures, what you see is what you get.
