I'm amazed that in these days of technology, we haven't yet managed to eradicate accidents that are due to carb icing. As always, there are a lot of old wives tales out there.
We have eliminated it. Fuel injection, or the coolant based carb heaters on liquid cooled Rotax engines, or the electric carb heaters on air cooled Rotax and Jabiru engines all effectively eliminate carb icing.
It's just that so much of our community is still in love with such geriatric technology.
