The tiny little jets have varnish due to the gas drying up, ethanol is a little worse.
seafoam may or may not assist. I was told by a Cummins Diesel employee that surging was not good for the generator, but I don't recall why.
If you can inject a stronger carb cleaner and gas mixture into the bowl of the carb and start the engine, then killing the engine almost immediately leaving the mixture in the jets, well!!
The carb is not expensive, labor is. Good luck.
