sounds like your auto choke is broken, and someone has set the idle valve too high, meaning it doesnt cut out cold but idles to high when warm

check a haynes manual, and adjust the screw on the carb bit by bit until it idles warm around 1000rpm

might be worth checking the mixture screw whilst your at it, if running lean on cold, it could contribute the problem.
