What do you do with it? What is its purpose for you? Do you find it useful? I have a Honda EU 3000. Considering selling and purchasing the 831a. I guess my interest in the 831a is a little more useable electrical power and diesel fuel. I HATE worrying about clogged or gummed up carb... I realize that if I exercised and ran the unit like I was supposed to it would probably not be an issue and you should do that whether it be a diesel or gas burner....so I guess the decision comes down to power. What is the max resistive load you have put on an 831a? Can you start a 2.5 ton HVAC with it? Can you run a 4.5KW resistive load with it? Any feedback would be useful. I have been bitten by the MEP bug and looking for another unit. I currently have an 803a and am considering a 802a, and 831a.
