Some coming over normally to find boss (8)
I believe the answer is:
Here is my best explanation:
'boss' is the definition.
(I've seen this before)
'some coming over normally to' is the subsidiary indication.
'some' indicates a hidden word (Some of the parts of the word are used).
'governor' can be found hidden inside 'coming over normally to'.
'find' is the link.
(Other definitions for governor that I've seen before include "Motor control to regulate speed", "Head of a US state", "Regulating device", "Device that controls, speed of an engine", "Boss", "Device to control speed of engine", "Official appointed to rule", "State ruler", "Person in charge of colony, prison etc" and "US state head".)
