If you notice the auction photo of the nameplate the engine is 3.5 hp @ 1800 RPM. That means the plant cannot make more than about 1800 watts continuous. No way it can be a 3 kW genset based on the nameplate horsepower. The seller answered some questions I sent. The whole thing apparently weighs only 200-300 lbs. This is a really small machine and $1K is a lot of dough for what is obviously a well used machine. I think I`d be better off spending that kind of money on a new 10 HP+ Changfa engine and new 5+ kW ST head.
