Being serious for a moment folks,
After transitioning from Lycoming powered A/C to one with a small Continental be aware! the 'A' and 'C' series in particular, really, really do ice up for a pastime. We're talking full carb heat every 5 mins in the air for 30 seconds. A good blast before pulling the power for a descent, then full on for the whole descent, curcuit and approach.
I personally leave it on all the way in, but some dump it on short final.
