I have a Porter Cable 5500 watt generator than is coming up on its 20th birthday. It starts with the first pull every time and has never given me any problems. It uses a 10hp B&S engine. We use it to power our house (via transfer switch) in the rare event of a power outage, usually lasting less than a few days, worst case. I am happy with the power output. It probably has less than 500 hours on it and has been maintained and stored fairly well.
I am concerned that I am on borrowed time with this unit and wondering if I should replace it with a new generator (Generac 6500). I would, of course, sell the old one for a few hundred dollars since if runs and performs fine at this point.
What would you do?
