Ran fine all last summer, at end of season, changed all filters, oil and aniti-freeze, stored with diesel stabilizer, exercise approx every 30 days for approx 30-45 minutes on warmest days. Last week preparing to take a trip south. Generator starting fine as usual, after approx. 30 minutes began to slowly surge slightly. The surging was never rapid but after another 10 minutes the idle speed began to decrease, some smoke from exhaust so I shut it down. Let sit for half hour. started fine, again run approx 20-30 minutes same symptons. Changed fuel filter dirt or moisture. Relaced electric fuel pump. Same exact problem. Now what?
