If it starts initially, then it has spark. most likely the jets on the carbureator are clogged. You should remove the carb and clean/rebuild it.

The idle control switch allows the generator to go into idle when there is no demand form the appliances connected. This saves gas and increases the life of the generator. Damage can occur for some appliances like a refrigerator/freezer because the voltage and frequency are not prepared for the load resulting in a low voltage bad startup that will damage the appliance. Suggest that you leave the idle control switch off while any motor/electronic devices are connected.

The throttle control is likely a choke function for starting. These generators are designed for only one running speed to produce the necessary 60 cycles per second and voltage.
The following link is to a Canadian web site that later in the detail report describes the concern of idle control. In addition it provides good insight to the operation and use of portable generators

Your generators take ordinary 10W30 motor oil.
We use these things on the job.
Don't turn engine upside down or on its side to drain oil, or oil will run into carburetor

high idle screw or governer

Because it running lean, too much air in the air/fuel mixture. I can only give a suggestion and it's a rule of thumb I follow regarding basic internal combustion tuning. With this condition I locate the fuel adjustment screw, usually located after the throttle plate (butterfly) which controls the amount of fuel into the mixture.

I would set it up to run richer then open the choke until it idles effortlessly, without any assistance. When it's too rich, the engine's revolution would be to high and probably cause it to smoke a little and I back off the adjuster. The best level is that it shouldn't stumble and cut off. Once this is optimal, hard starting and unassisted idling should be eliminated.

Hello. I'm sure that you've checked your air filter, so check the pinhole vent on the fuel filler cap. Next time it dies, immediately crack the cap and listen for the sucking sound of air rushing into the tank. If you hear this, clean the cap!
