Lynn, I would look under my car after I shut it off to see if anything is dripping. Also check your tail pipe and see if the smell is coming from there. Next I would take it to an AutoZone and get a free computer diagnostic to see if it is reporting anything.

Check the gasket on the fuel fill cap. They crack with age and may be allowing vapors to escape as the fuel expands in the tank. This can also cause the check engine light to come on.

Could be a fuel rail leak on the line that supplies gasoline to the carb. you may not see liquid as it will evaporate on top of the hot intake.
