It sounds like the battery is dead. Take the battery to a place like batteries plus and have them test it.

clean the spark plug

Check voltage output with meter.

Check the oil filter.

First verify that the breaker for the outlets is not tripped and make sure that the generator is running at full operating speed. let it run for 5-10 minutes and check for output power. If there is nothing, there are two possible problems. One could be that the automatic voltage regulator is bad. The other is that the field needs to be flashed - a high possibility if the generator has not been run in a long time. There are many videos on the internet that show you how to solve both of these problems. Just do a search for No output from a portable power generator.

Check the rotor slip rings and brushes first, the rings should be clean and bright

take the end cover of the generator alternator, and you will see the brush block assembley where it touches the rotor slip rings, clean the rings while you have it open

It sounds very much like no AC output from the stator to the run circuit, or the main PCB failure

faulty solenoid on starter motor if battery is good

many generator problems is in the carburetor when you put a load the engine requires much more fuel and air most likely it's your carburetor jet and fuel tube are resticted especially if you had the generator stord for quite some time
