strong exhaust smell

Have a question about my '82 Coupe 2.2

While travelling at 55mph+ or accelerating strongly, the exhaust smells very
very rich.  There is no smoke.  It is so rich people who smell my shirt say
it smells like pure exhaust.

Best I can describe it as standing behind an old VW Bug or Bus while it is
idling-it smells like exhaust.

I have not fooled with the mixture.  I figured if it is running overly rich
it will foul out the plugs.  Plugs look tan and nice, so I doubt the mixture
is way off.

Other ideas?
Thanks
Paul

BTW yes the oxy sensor is hooked up, as well as the cat and 2 standard
mufflers.
