My Onan 4000 gas generator sounds like it is starting, but it immediately dies as soon as I release the starter. I am barely beginning the process of introducing myself to the generator since acquiring this MH. I have no clue how long since it ran last. I know the basics about gasoline engines but have no manual for this specific generator.
I primed it by pressing the prime button (it apparently has an electric fuel pump). Gas dripped ( have plenty of fuel in the tank). I think it was from flooding and not a leak. I removed the air filter and gave it a shot of starting fluid. It started for a few seconds with black smoke (I assume because it was flooded). This means it is getting spark though the outside of the sparkplug looks OLD. It could be original since it has less than 200 hours of runtime.
I will pull the spark plug today to see what it looks like. I will see how difficult it is to drop the sediment bowel and check for trash, water, or a stuck float. I guess I could shoot some SeaFoam carb cleaner in it. I guess I will search online for a manual.
I have no idea what the altitude adjustment is. I assume it changes the air mixture. It was set at 10,000 ft, and we are at less than 100 ft sea level.
