Sometimes the pilot light on a gas stove can be set too high, which can cause a gas smell. When it's too low, it can have trouble staying lit. Both problems can be solved by adjusting the pilot lights for the stove and oven.
Lift the top of the stove and secure it in place.
Locate the pilot lights and trace the two aluminum tubes back to where they combine.
Turn the screw where the two aluminum tubes join. Turn the screw clockwise to lower the pilots and counterclockwise to raise the pilots. Sometimes the adjustment screw is underneath a piece of tin that runs along the front of the stove. There is usually a hole in the tin cover that a screwdriver can be inserted into to access the adjustment screw.
Follow the aluminum tube back from the pilot in the oven to the adjustment screw to adjust the oven pilot.
