Turning gearwheel with skill in kid’s vehicle (2-4)
I believe the answer is:
go-cart
'kid's vehicle' is the definition.
'go-cart' can be an answer for 'vehicle' (go-cart is a kind of vehicle). I'm not certain of the 'kid's' bit.
'turning gearwheel with skill' is the wordplay.
'turning gearwheel with' becomes 'goc' (I am not sure about this - if you are sure you should believe this answer much more).
'skill' becomes 'art' (I've seen this before).
'goc'+'art'='GO-CART'
'in' is the link.
Can you help me to learn more?
(Other definitions for go-cart that I've seen before include "Low racing vehicle" , "Got car (anag.)" , "Vehicle used for recreational racing - baby-walker" , "Child's vehicle" .)
