You can run carb heat as much as you want to, No harm to the engine. I tell my students to use it, its good operating procedure. All the airplanes with carburetors have the problem, and I don't want to get into some helicopters like the R-22 and some versions of the 300 and Bell 47's. These days even airplanes like the 172 will be fuel ejected. takes care of the problem but adds some other issues. I would be care full with Mo gas due to the ethanol added. Mixes with water not a good thing!
He mentioned haze [HZ] as a "visible moisture" condition which is not entirely accurate. Haze is composed out of dry particles (sand, dust, smoke etc). He should have said Mist [BR]
I've had carb ice in the C152, once pretty badly. The relative humidity was ok at the departure field but ice was picked up over a river valley. I assume it happened because of evaporation over the river. The carb heat worked just enough to maintain altitude but I turned around rather than risk a flight into rising terrain. I'm a lot more inclined to use the carb heat now.
Quote from ASA's A PILOTS GUIDE for the CESSNA 152 "Almost certainly the most common cause of engine rough running, and complete engine failure, is carburetor icing". Great video on a very important topic. Thanks
great video

i run mo gas in my 150 all the time year round. I kinda forgot that mo gas was more promenent to carb icing. glad I watched this.

I got carb ice in a J-3 cub once. Just as I was turning final to my emergency landing field the ice thawed (I had carb heat on) the engine came back.

my motorbike suffers badly from carb icing and this video is a good insight to what actually happens.
