5500 watt gen

I was able to get the electric start model and I am glad I did. I find that the electric choke is hard to get use to when it first start but after about a minute the generator purrs. I have two other 5000 watt generators(Coleman) and they each sound like they are twice the noise level as the Yamaha.
