Thank you so much for the response. I was told there were a couple of Onan gurus on this site. It's hard to believe it would be my fuel pump/filter. I walked into cummins in Fort Myers, FL a week ago and purchased both new to match my model number Onan. Replaced them that day.
Carb bowl is filling up. I popped open the carb drain and out came the 3-4 tablespoons of gas. I made sure to fill the gas tank to full right before we parked a couple days ago knowing I was going to change the carb. I don't think it's a clogged filter. The only filter between the gas tank and the carb is the brand new one attached to the back of the brand new fuel pump.
I always start the gen with the breakers off so there is no load.
I tried priming and starting it again and I didn't need to spray starter fluid in the carb to get it to turn over this time, which was exciting. But it immediately started surging and backfiring when it turned over so I cut it off. I don't want it backfiring and dirtying up my brand new carb.
I'll try the gravity feed tomorrow. Any suggestions if it's surging and sputtering even with a gravity feed? Thank you for the help.
