oven pilot will not light

Based on your model number and information you provided, the gas supply to your bake burner pilot assembly comes from a supply tube which originates from the oven thermostat.If you carefully disconnect the tube from the pilot assembly and see if you can light the end of your tube as if lighting the pilot and if there is no gas supply present then the oven thermostat would need to be replaced.Although it is and older range the thermostat is still readily available and the part number based on your model number is WB20K10033. Good luck.
