Bruce,
Now that you have your issue solved, try this trick for smoother Onan starts.
To Start after a period of non-use (carb bowl is empty)
- Press and hold the Prime button and listen for the sound of the fuel pump to change (mine gets quieter)
- Fuel pump is now primed and pumping fuel
- Continue to hold the Prime button and listen for the fuel pump to change sound again (fuel bowl is now full and fuel pump is dead-heading against the closed needle valve.
-Now continue to hold the Prime button and press the Start button.
-Once the Onan engine fires, continue to hold the Prime button until the engine is up to full speed
-Now release the Prime button and the engine will continue to run.
If you are re-starting the Onan and it fires then quits, the relays on the control board may not be picking up fast enough. In that case simply press and Hold the Prime button, crank and hold the Prime button until the engine is up to full speed.
The Prime button simply bypasses the Control Board (same as connecting Pins 5 & 9). Holding the Prime button while Cranking and up to full speed simply makes sure the ignition gets a continuous supply of power throughout the startup.
