You kept your word. I have not unpacked it hope I never have to.

Champion 2800W/3100W

I now have a couple hours running time on the generator.
Starting on second easy pull and running smooth.
So, no complains.
And absolutely no complains with FactoryPure.

To good to pass up

This is my third champion. I already have a 75531 model which is basically this same generator without parallel. It has been a solid dependable unit the last 6 years for both camping and power outages. When I stumbled across this one I couldn’t I just couldn’t turn it down for the price, I was willing to risk it being a re-furb. Mine arrived looking virtually brand new even though the manufacturer date was 2016. Fired up on first pull. I didn’t really need two of these, but one will get the high altitude jet and be dedicated for that, at least that’s how I justified it to my wife.

Champion generator

Open the box. Our oil and gas and followed starting process. But Generator will not start. Talked to Paul Cole at Champion repair and he told me to take it to a repair shop. It is at a local repair slop now.

Champion 2800W/3100W Portable Inverter Generator

Unpackaged and broke generator in according to the manual. (I did switch out the spark plug for an NGK as stated in previous reviews). Break in went great. Used almost continually over the 3 day Memorial Day weekend. 85 deg out all days. the heaviest load we put on it was lights, with microwave, and fan. Handled it with no problem. did not have to unplug anything to use the microwave. Happy so far with this purchase.
