Where is the problem -- in the oven burner or a stovetop burner?
If something got spilled on a burner ring and clogged the small holes, especially near the igniter, the burner will be slow to light. A stiff wire (small enough to fit) can be used to clean out the holes.

Just because an igniter glows, does not necessarily mean it is good. The following link explains:

It sounds like you may have had a couple of problems. The gas smell concerns me though. If an igniter is weak, you shouldn't get any gas flow in the oven. This is a designed safety feature that prevents free flowing gas from filling up the oven cavity without ignition. I would recommend checking your igniter for the proper current and/or replace. The link I provided, lists the steps required. If you have any questions, please let me know. I hope this helps you.

Replace the oven glow bar ignitor.

i would replace the igniter and go ahead and replace the gas safty valve eather the ignitor is not allowing enought amps to open the gas valve enough to light or the valve is opening to slowly eather way i would go ahead and replace both this could be very dangerious is not repaired.

Lift the top of the stove up. Then there should be 4 nuts on the backs of the burner controls. Turn them left to open the valves for nat. gas. You want just a small amount of yellow on the flame. Then take the droor out of the oven and there should be another nut close to the gas valve for your oven flow. Do the same to the oven.

You will have to get rid of the mice first . Then take unit out and remove any nests that may be in there and clean it then fire it up it may smell but will kill off any smells .

too much air on top burner ,delayed ignition on oven ,ignitor not lined up properly or check gas presure may need regulator adjustment or replaced. gas 784
