The question might be at what power setting.

1. For a full throttle decent, I leave the mixture alone. Once the MP  
gets to 23 or 24 in, I pull it back as necessary. Every once in a  
while the engine will start to run rough. That means it is time to  
wind in some fuel.

2. For an idle decent. Who knows what happens because, who would do it?
