Customer Question

I have an Onan generator on my toy hauler, I can prime it and push start and it will start and run for about 5 seconds and cut off. What could be causing this?

Sounds like the carb jet(s) are getting clogged with ethanol deposits. Would need to remove the carb and clean out again. Either they didn't get them all cleaned out, or new deposits have developed

I am not an ONAN Expert, but from the issue that you are having, it is a carb issue. The carb is not pulling its own fuel to run properly
