It is interesting to note that fuel acts as a refrigerant in a carburettor whilst it is also needed to keep the engine running.
The problem will be more pronounced if
the engine is operating at low power. In this case, the airflow through the carburettor will be partially impeded by the throttle valve. This valve not only provides more area for the ice to form, it also increases the partial vacuum
downstream of the valve, and that will cause a further chilling of the air and the water droplets.
Under these conditions the engine should normally be leaned. If this is not
done, then not only are you using more
fuel than you need to, but you are also
putting more refrigerant into to the
carburettor airflow, thus increasing the
likelihood of carburettor icing.
