Have to sell; moving. Trying to figure out how many Watts is this generator in my garage and how much to ask for it? I fire it up every month to make sure it's working. Bought it after Hurricane Jean in 2008. Never had to use it since. I also had a man service it about a year ago (unfortunately he's since passed, bless his soul, so I have no one to ask for advice). Please help. See pictures attached. . .live in the Tampa Bay area if anyone is interested?
