Remove clogs, seeing good time ahead (2,6)
I believe the answer is:
up sticks
'remove' is the definition.
(both can mean to leave a place)
'clogs seeing good time ahead' is the wordplay.
'clogs' becomes 'sticks'.
'seeing good time' becomes 'up' (up can mean cheerful).
'ahead' means one lot of letters go next to another.
'sticks' put after 'up' is 'UP STICKS'.
(Other definitions for up sticks that I've seen before include "Move house(colloq.)" , "Make off" , "Move away without warning" .)
