And I had a similar problem on my first toyhauler. The generator had 42 hours on it and was surging badly. I did 2 things and one of them fixed it

One of those fixed it and I'm reasonable certain it was the gas.
If you don't know how old the gas is I would suggest getting it out of there and putting fresh gas in.
