I concur,
I brought back my old car from East Asia as a personal import. Because it wasn't for the european market it didn't have an intake hot air device fitted.
It occasionally suffered from carb ice and would cut out in the most inconvenient of places, usually after idling in traffic with the engine not fully warmed up. It would also do it on the motorway at certain speeds, but if I slowed down (as I was forced to do due to the misfire) it would pick up and go again as the engine bay heat got to it.
It occurred in cool, humid, weather and was most noticeable beneath thunderstorms (classic wx for it). It was possible to see the ice in the carb if you were quick enough to get the air filter cover off.
