Just to keep things in perspective, the P2006T does not in my experience (maintenance of and being involved with operations of many of the type over a number of years) suffer from carb icing in flight in/above the UK. They only seem to suffer from it when the engines are cold, pre-flight. For those that don't know, power checks are not carried out on a Rotax 912S until the oil temp has reached 50°C by which time carb icing does not seem to be an issue.
You certainly do not want to be operating a P2006T with the carb heat on hot all of the time, it won't like that as the carb heat system does work well when in hot and as with most aircraft engines, there is a drop in rpm when it is selected.
