My EU2000 started running rough after about 500 ours of use. Would only happen when using the ECO mode and running for several hours or if it was very cold outside. Before this last trip I started using Seafoam cleaner in every tank. This last trip I ran it several nights at 6F and no more rough running. Running in ECO mode just powering the converter it will run a bit more than 12 hours.
I believe that there is a fuel filter inside the fuel tank as well as the tubular screen in the filler neck. I'd like too change the inside one but haven't been able to figure out where it is. Anyone ever changed it?
