Steve,
 There is no one procedure that always works consistently on 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 vapor on the first attempt.
If the engine cranks more than 6 or 8 revolutions on the second (or third) 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 reasons.  There is less chance of a fire and also, it's easier add some fuel than to dry out a flooded engine.  And, knowing you're on the lean 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 revolutions ) would clear it up.  Extended cranking has never been needed.
 It always has started.

I have an IO-360 in my Lancair that tends to be tempermental when trying to restart after shutting down and fueling.
 
Does anyone have a preferred hot start procedure that works with their tempermental engine?  I've tried the procedure in the handbook and several other variations.
 
Normally, I crack the throttle, mixture is ICO, turn boost pump on, mixture enrichen for a few seconds until fuel flow registers, boost pump off, mixture ICO then crank.  What usually happens with a hot start is I'll get a few firing prop rotations and that's it, it will just stop.  I've tried several different combinations of mixture and throttle settings when it starts firing, but nothing works consistently.
 
thanks
