Fix badly? (3)
I believe the answer is:
rig
'fix badly?' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for rig that I've seen before include "Fit with sails and tackling" , "uniform perhaps" , "Large American lorry" , "Manipulate fraudulently" , "Provide with clothes - for oil well?" .)
