Small Continentals are said to be more prone to carb ice, because the carburettor is more exposed. Liberal use of carb heat helps with these, particularly in the circuit. Bear in mind the fact that this effectively causes the mixture to become more rich, so care of the plugs is important.
Kinner Radial engines are also known to be more susceptible to carb ice.
In either case, being aware of likelihood of icing conditions is a key to mitigation.
The worst carb ice I ever had was my first car, a clapped out Ford Fiesta. In freezing fog on the motorway, my top speed dropped from 60 (it was old!) through 50 to 40 at which point I pulled over. It was late at night and no traffic, otherwise I'd have pulled over sooner. Anyway, 15 minutes later it ran fine. On inspection, the air box had fallen off, having been attached with a single wood screw so the intake was cold air only. I treat carb ice with much respect after that experience...
