Smaller continentals definitely.
The main aeroplanes I've seen carb ice on are Super Cubs and older C150s, often at its worst whilst on the ground.
912 engined modern microlights, and reasonably modern PA28s are probably the least problematic in my experience. The PA28-161 manual even tells you NOT to use carb heat on approach unless you see positive signs of carb icing (although a lamentably large number of flying instructors are convinced that they know better than Piper in this regard and make students use carb heat on approach, effectively flying them like Cessnas, which do need it.)
