Powerland Pro Generator

[plpitts1]

Hello, I have a Powerland Pro 10,000 Watt Generator 16.0 with an Auto Throttle switch. If there is a model number on this I cannot find it. No name on the motor. Came in not running, bad gas in the fuel bowl. Cleaned Carb. in Ultrasonic cleaner several time, flushed tank, and installed new fuel filter. Runs great, even with the Auto Throttle on, except that when the Auto Throttle is engaged the motor has some vibration. Any Ideas on what I am missing??
Thanks,
Pat

Should be a PD10000E. But since it is put together in China who knows.

Link should at help with determining the part numbers and have the user manual.
