Sounds like there's a blockage in the carburetor main jet metering circuit. A thorough teardown (including removing the metering orifices), followed by long soak in carb cleaner then a blow out all the passages with compressed should cure the problem.

As the others suggest carb icing is a normal characteristic of these tractors - even when the carburetor is working correctly. Icing seems to be worst when it's about 40 deg and 100% humidity out. Warmer and colder temperatures diminish the problem.

Stuff that helps with carb icing: Obviously both carb mixture screws must be set right so you can get the choke off immediately after starting (choking seems to make icing worse). Have the right thermostat is installed and working. Use a winterfront over the grille to block airflow thru the radiator. (An old poly feed bag held in place with a couple bungees works great!). Minimize idling - put the engine under load ASAP after startup. Shut the engine off (or idle it at � throttle or so) if it's gonna sit unloaded more than a couple minutes. Dumping a couple bottles of fuel line de-icer in the tank sometimes helps. Make a temporary sheet metal shield to catch warm air off the radiator and direct it over the carburetor, or install a heat houser. In extreme cases you can put a flex hose on the air cleaner inlet then arrange the hose so it picks up hot air off the exhaust manifold.
