It's a smarter tools ap2000i 2000 watt SunPower pro gasoline inverter generator driven by a Yamaha MZ80 engine. It's only been used about 4 hrs total. A or 4 times other than that, It hasn't been used at all. It's just sat in storage, it is basically brand new. If you don't believe me just look at the spark arrestor there's no carbon build up on it. Trust me if it were just cleaned with the wire brush or something, you'd be able to tell. Come look at it for yourself. You can be the judge. It has hardly been used is why. It starts on the first Pull almost every time. Unless it's been sitting for a few days. Then it takes two or three tugs to get the gasoline up into the line again. It had 2× 110v/115v/120v outlets. It also has a Smart Throttle so it only produces as much power as the load commands of it. I changed the oil once for resale other than that it's only had the initial fill up. They retail a little over $600.00 out the box. So I figured it's a steal of a deal. I mean I do not have much need for it now. I may be open to trade depending on what it is you are interested in trading. Other than that I am asking $325.00 or best offer. Hit me back and let me know. You can come check it out and see it run before you buy it.
