If you have a automotic choke, that is a way in which the carbie senses that it is cold, closes the choke to enrichen the mixture. It is a bit crude, and Im not sure the auto choke will do anything once you are driving along and it has opened up the first time.
Many carbies (on a 4K, 2T, 18RC etc), have a temperature operated bi-metal valve, which opens when it gets hot, and this bleads extra air past the throttle which changes the fuel mixture (leaner) for the warmer air.
So yes, carbies are made to sence and change the mixture for different temperatures. Sidedrafts do not often have this, as the cold start circuit in manualy operated, and my ones at least don't have the bi-metal valve. Later ones may.
