What could produce minor hitch? (8)
I believe the answer is:
drawback
'hitch?' is the definition.
(thesaurus)
I don't understand the rest of the clue.
(Other definitions for drawback that I've seen before include "Hindrance - disadvantage" , "Hindrance - retreat" , "Fly in the ointment" , "Disadvantage, problem" , "Obstacle" .)
