Service Chippys had the carb heat wired to 'hot' (warm, really). But then they had big long runways and few pie eaters in the seats.
Ours is in 'cold' for t/o, then immediately put into 'warm', where it stays for the rest of the flight (unless I remember to flick it to 'cold' on a go-around).
No check list needed once familiar. It really is a very simple aeroplane. Easy to fly, very difficult to fly well. An ideal trainer.
