I have an extra Onan 2.3 KW onboard. I am pretty sure that it needs a new fuel pump, It has a new carb. It is now an extra cause I was dealing with a steallership and they don't know s*** about genny's. Any way the new gen got put in and did the exact same thing as the other was.
When I treatened them, they found that the fuel pump was never hooked up on the new unit.
Any way long story short, I would be willing to give up the extra one for cheap if you were in my neck of the woods. At 130ish lbs I don't think shipping would be cheap.
And if you never would use it, then you can carry that amount of weight in beer.
