Jim,
Does the same apply to the Europa Classic, if so, what precautions do you
recommend to detect and eliminate it?
This is a very important area - which presumably we all need to act on?
(I haven't had any apparent icing in over 100 hrs in mixed flying weather -
but that could be due to the fact that I've avoided icing conditions).

Just so we are clear on this, Europa XS's fitted with 912 or 912S's ARE
vulnerable to carb icing and you should take precautions to detect and
eliminate it. It has happened more times than reported in Rotax's I believe
due to the fact that it does not have the symptoms of carb icing as we are
taught to recognize during our training. The proximity of the exhaust pipes
is not enough. That will only serve to heat the carb bowls and the fuel, not
the incoming air, I hope this clears up some of the confusion.
