Steve,
 There is no one procedure that always = works consistently on=20 my engine.
 I do no priming at all, (crack throttle, mixture cut off) and = normally the same sequence must be repeated a second time.
It doesn't seem like it's possible for the fuel system to clear out = all the=20 vapor on the first attempt.
If the engine cranks more than 6 or 8 revolutions on the second (or = third)=20 cycle, I've probably been too stingy with fuel and need some = prime.
I believe being on the "too lean" side is conservative for several=20 reasons.  There is less chance of a fire and also, it's easier add = some=20 fuel than to dry out a flooded engine.  And, knowing you're on the = lean=20 side is much better than not having a start and not knowing what it = needs.
On several occasions when I did flood it, more cranking (maybe 8 = to 10=20 revolutions ) would clear it up.  Extended cranking has never been=20 needed.
 It always has started.
