Carburettor icing is not at the first start of the day. The scenario is that it starts at first start of the day, then maybe 20 miles down the road the air flow through the carb is reduced to zero by the formation of a large chunk of ice. Of course by the time the AA man (me) arrives the ice has melted and the engine starts. I found it mainly occurred in damp foggy weather at just over freezing temperature.
