Mount, in turn, but a little awkwardly (4)
I believe the answer is:
arab
'mount' is the definition.
(Arab is an example)
'turn but a little awkwardly' is the wordplay.
'turn' says the letters should be written in reverse.
'but' becomes 'bar' (both can mean 'excluding' or 'except').
'a little' says to take the initial letters.
The first letter of 'awkwardly' is 'a'.
'bar'+'a'='bara'
'bara' backwards is 'ARAB'.
'in' is the link.
(Other definitions for arab that I've seen before include "Fine horse breed" , "Qatari or Omani, say" , "One from Saudi" , "Small, lively breed of horse" , "Saudi, e.g." .)
