Cant speak for that model but I just picked up a champion 2000 inverter. I had issues trying to get it started so I called customer service and the guy (American) said the unit was probably turned over at some point. He walked me through it and we got it running, He is even sending me a new carb assembly free of charge just for assurance. Champions customer service is fantastic, unlike any service I've experienced before.
Also Rural king is still running their special 399 price on these units. Very quiet and a big upgrade from the 3500/4000 watt model I previously had.
Love our two. Did have some issues with the first two we had but they were when they first came out. We called them about it and they ended up giving us two brand new ones to replace them and haven't had any issues since.
