I filled the tank all the way up, towed the trailer 500 miles and then the generator fired right up in 115 degree heat and zero surging for an hour. Started it again a little later and it surged again. So it seems to be getting a little better at least. Too hot out to work on it more for now, as it is still functioning for my needs.

Oh and I tried with the gas cap off to no avail.
Any update on your Onan? I have same make and model and am fighting the surging with little to no load too. I tore carb down twice today cleaning it and clearing any gummed up ports to no avail. Everything was pretty clean to start with as I only have 114 hrs and it is a 2017 model.
