   Depends on how long it takes the engine to warm and to taxi out, get in
   line, and get into the runway.

   Myself, I'm not all that thrilled about the idea of starting my takeoff
   roll with wet plugs.

   You do do a run up don't you Keith? :)
   If you pull the leaning knob that should clear the plugs when
   you do a run up.

   Even if the exhaust is pulling some fuel at idle, it does not mean
   the mixture must be rich. The fuel pulled by the exhaust goes out
   the exhaust, not into the combustion chamber.

   You would use your mixture knob to adjust mixture to the lean side
   at idle -- something that's a good idea on any engine, for the very
   reason you mentioned.
