There should be a thermocouple in the pilot light flame that once hot enough, few seconds, allows gas flow through to the main burner. Our very first, and very old RV, did the same. Previous owner had shut off the gas control knob the wrong way to many times and inadvertently unscrewed the thermocouple, simple fix. Whatever the magic chef setup this thermocouple and it's operation is where to investigate.
