  I've noticed when I shut down the P218 on the welder while the air filter is off, when the gov. opens the throttle all the way it is spitting a gas/air mixture out of the carb throat. Is this normal? It starts easy and runs great and has 90psi comp. I would think if one or both intakes weren't closing all the way it would be hard starting.

Mike, your Onan is doing its job properly. 


As it is shut down, the governor thinks it needs more fuel to pick up speed, so it will open up all the way.  The engine is hot.  If it is what I am thinking, at the last few strokes before it cuts off, it will pop a few times as the unburned fuel sucked in after the ignition was cut off burns. 


I'm surprised that they don't have a fuel solenoid on it, that's what those things prevent when they don't aggravate the mechanic.
