I was going to reply to APU, but suddenly found a reke of "hidden" posts on the subject.
IMHO, the 0200, per se. does not , of itself, suffer "carb icing" I'd suggest that it's the specific installation that causes this problem.
"the other brand" suffers less because it's carb is sheltered from the icy blast of cooling-air.....a deflector baffle would be too easy, for the 0200...think of the certification-costs!
Whilst I accept that carb. heat will rob a bit of power, the increased safety is out of all proportion to the slight performance degradation.
Rotax is a different animal altogether...there are induction heaters on the market....again, there is a performance hit,but they apparently work well.
Have seen icing on cars as well, rare but not unknown....again, most cars have a thermostatically controlled air-blend-even if it's a simple bimetal-strip and pad over the "alternative" hot air pickup (Minis/metros/marinas etc. used a crude, simple and effective one like this) but it seems that stuff like that is too advanced to fit to certified aircraft (permit stuff would probably be OK )....the" either clean. filtered ambient...OR....hot 'n dirty from around the exhaust-manifold." is just so antiquated ,it should have been legislated out of service in the 1960's
All just my opinion , of course, as an "outsider" looking in.
