So, the new, reconditioned Onan is not doing it's job reliably. My son picked up the motorhome to take it on a trip to Colorado Springs last evening and drove it about 7 miles to Costco to get gas. He shut down the generator while pumping gas and it would not restart until some time after he got home to his house, another 5 miles.

I had set the timing and adjusted the carburetor and run the generator, under load, for at least a half hour with no issues. I suggested that Mark re-adjust the carburetor, which he did and said it was running better. It quit again on him later and he decided to replace the fuel pump that came with it, a 7-9 psi solenoid type, with a new Mr Gasket #425 (2-4 psi). He did that quick this morning before they left and said it was running well.

After a stop at Walmart on the way out of town, they left it running, but it had quit while they were shopping. In Deming NM, it restarted, but apparently only ran for about 45 minutes before it quit again. I looked up the spark plug number and suggested he check to make sure it has the right plugs in it, Grasping at straws here.

Any suggestions?
