Why is the gasoline generator not starting?

There are many reasons why a gasoline generator may not ignite, such as no gasoline, poor quality gasoline oil, damaged spark plugs, components damaged ignition system such as high voltage boxes, igniters, magneto coils, etc. resulting in no high voltage, clogged carburetor (this situation is more likely to occur if it is rarely used), insufficient cylinder pressure, air leak in the valve or intake valve and buffer carburetor interface, improper use of the shock absorber or inefficiency, etc., these are gasoline. The common reason the generator won't fire is to first check and clean the carburetor and see if there is high voltage in the spark plug.
