Hello, my name is ***** ***** I am going to assist you with this.

1. What is the full model number of the genset?

2. What do you mean by "won't stay running"? It only runs while you hold the start switch, but quits as soon as you release the switch? It runs for 10 seconds? an hour?

3. If it runs at all, while it runs, does it run smoothly, or is it running rough/surging?

4. Have you done anything to the unit at all?

just wondering if its the fuel pump
Expert:  Hank F. replied 2 months ago.

This actually sounds morel like a bad carburetor.

You can easily test the pump by removing the fuel line from the carb, unplugging the tan fuel line from the pump, and jumping 12V directly to the pump. I usually just touch the tan wire to the battery post of the starter solenoid, in the lower right corner of the control panel.

If the pump is working, the carb is bad.

Yes it is. It is located on the right hand side of the genset.
