I just resurrected an EU1000 that hasn't been run in 10 Years. I was astounded it ran at all but it did, albeit poorly with all the symptoms described in the thread. It also dumped so much gas into the engine it ended up in the crankcase thinning the point of disassembling the carb but I ending up doing a series of oil changes to flush the crankcase and to get her running right I used Sea Foam in the gas, and shot carb cleaner into the intake while running. Once all that was done I took the spark plug out and gave it a good cleaning. She's outside right now running in Eco mode with a 600 watt light plugged into it purring like a kitten. Once this tank of fuel runs out I'll change the oil on last time and load it with Mobil 1.
BTW, the genny cost me a bottle of good single malt and a few hours of my time (to get it running right).
