Its run about 30 minutes or so (picked it up this morning). Its an inverter type generator though, little bit different operation than a conventional generator (output not directly linked to engine speed). I think its an electronic problem, not mechanic. I can always manually work the throttle to make it to run with a load, to get fuel through the carb so the Seafoam can work its magic. I'll probably do that tomorrow after I get home, load it down and let it cook a little.
