That's a good idea up to say 5,000 feet. After that you're just too
rich IMHO. In fact, when I had the Debonair I couldn't get over 8,000
at full rich. The Cont engine just didn't put out power above that
altitude with the mix rich.

And in case it isn't obvious to some, you are referring to a normally
aspirated engine. I fly a turbo-normalized V35 with a Continental IO-520
engine.

Not only do I have to keep the mixture full rich on climb out, I then have
to engage the low fuel pump setting from 5k to 10k, followed by the high
fuel pump setting from 10k on up (assuming the cruise altitude is in the
teens up to the very low twenties). If this is not done properly, the
cylinders and turbo inlet temperature really start to really heat up.
