Carries goods including old instrument of punishment (6)
I believe the answer is:
stocks
This might be a double definition.
'carries' is the first definition.
('stock' can be a synonym of 'carry')
'instrument of punishment' is the second definition.
(stocks is a kind of instrument of punishment)
'goods including old' acts as a link.
This may not be correct. Some or all of it may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for stocks that I've seen before include "Capital holdings often accompanied by shares" , "Fragrant flowers; shares" , "In which miscreant is locked" , "Reserves and inventories" , "heavily-scented flowers" .)
