I had one of these for several years on the farm and although noisy it got us several outages, some as long as 2 days.
The only problem I ever had was when I ran the gas out of the engine. The ethanol or something made a mess in the carb. According to the repair shop you don't always get ever drop of gas out of the carb.
So I would not run it dry. Add stabalizer and run the thing every 2 months for 10 or 15 minutes. That is what I did and never had another problem.
Paid $425 for the generator and sold it years later for $300.
