Does the engine idle smoothly? If do, I'd leave it alone. You may improve things by tweaking the idle mixture screws, but the odor will not go away. I have never seen a carbureted engine that didn't smell rich at idle, two barrel, four barrel, or Tripower.
If anyone disagrees or has suggestions, please post.
