Row generating a stink (4)
I believe the answer is:
rank
This clue is a double definition.
'row' is the first definition.
(as in a taxi rank)
'a stink' is the second definition.
(I've seen this before)
'generating' acts as a link.
(Other definitions for rank that I've seen before include "The military row is coarsely overgrown" , "fare might be found here" , "Foul - station" , "Grade; flagrant" , "Violent old-fashioned" .)
