The only running time it has on it is every couple months I take it out of the garage and run it 10 minutes then it goes right back in and under cover. Have only put clear gas in it with fuel stabilizer. Of course it starts immediately and runs perfect. I have a smaller genset if I need one so letting this one go to someone that needs it. I think $300 is a very good price for this unit. Not interested in trades, I have too much stuff already. Thanks.
