Am I right to think White smoke is a sign of unburnt fuel on a petrol vehicle

White smoke is a sign that water is entering the combustion chamber so could a sign your head gasket is in trouble.

Sounds like water in the chamber. How long have you run it for, if it was condensation, after a 20 mile drive you would expect it all to boil off.
I would take it for a fair distance drive, if it clears up then it was moister, if not sounds like HG trouble.

Wip the head off, get it skimmed and then put a new HG on :D

its also wise to check your brake fluid level have heard of instances of fluid leaking past the servo into the vac,when burnt off white smoke.
