Carb Heat: What's the deal?

[abgd]

I tend to listen to lots of people and also check with the official sources.

My view is that conditions and aircraft vary, so there can be no one true checklist to cover all situations. You get the basic protocol nailed, then occasionally adjust it on the basis of principles and experience. Hence my interest in what people here have to say. It would never have occurred to me that you could get carb icing as quickly as some here have experienced, for example, as the only carb icing I've ever encountered has been relatively insidious.
