Be an expert pilot...
If you need to know because you'll be flying the aircraft, may I urge you please to read the flight manual and go by what it says? 
There's far too much flying by bar-stool talk, don't be part of it!

50 deg rich of peak..........YUK.
Look up also www.gami.com
Go read avweb.com and look up John Deakins engine series in Pelicans Perch. I will show you why 50 deg rich of peak is the worst possible mixture setting to have.
POH's are written by Lawyers, not pilots.

Cruise between 26 - 30" manifold depends on the companies procedures. 2300 RPM in cruise and 75 degrees rich of peak during cruise.
it is a fun airplane to fly, I loved it when I was flying it.
Good luck,

Reading matters...
I speak with some experience when I say that you'll have no problems at all operating a fleet of PA31s if you fly them by the book.
The general point that some (though not all) flight manuals are not very helpful has some validity. This is even truer on bigger aircraft - with Airbus you must get your head around 'ze philosophie', and the new Boeing way of doing things is a return to some nightmarish SOPs which I thought the industry had grown out of in the late 80s.
The PA31 book, whilst it has its foibles, of course, rates as one of the better ones.
