I was never given any advice about leaning during my training, and when I asked the owner of the school about it, he said that it's cheaper to burn avgas than to have engines burn due to excess lean running. Don't know if it's true but it sounded plausible to me!
I always lean as necessary on injected engines but don't on non injected engines - don't know why force of habit I 'spose.
How many of youy brave leaners will actually lean back whilst say mid channel in a single- me , I don't touch the damn thing over water, no sir whatever it is coasting out it stays that way
