Hi all,
I'd be grateful for your wisdom on cold starts, please?
Specifically, on a 172.
I've been told to turn the prop by hand (about 10 turns) as part of the pre-flight, to get the engine to start more easily in this very cold weather.
I think I understood this has something to do with evacuating (old, viscous) oil from the cylinders? Is that right, and just how does this work, exactly?
Also, is it dangerous? No, I've been told,
as long as the mixture is fully set to lean.
Sorry if those are dumb questions, but I'd like to hear your thoughts/explanations.
