My '48 does the same thing when it's real cold and the humidity is high. Something about the gas vaporizing in the carb drops the temperature of the carb body enough to freeze condensation.
The old VW beetles carbs would ice up enough to stop running sometimes.
Best,
Mike

Could be. The more I think about it I remember the carb heat control on a Piper J3. Same idea only more vital.
I would still try the spray a little either near the joint while idling and see if there is any surge.

I don't think the icing on the carb is anything wrong, mine does that when it's real cold, especially if the temp is right at the dew point. The reason you see frost on the rear of the carb at that point is that is where the air flow in the carb is restricted by the throttle, so it is colder, and its on the rear and not the front because the rear is sheltered from the fan by the carb body so it isn't being evaporated. I have seen mine when it was very cold and snowing become competely covered in ice and frost while pushing snow. but as long as there is no water in the bowl or gas to freeze, it just kept going.
If you are not part of the solution,
you are part of the problem!!!
