About the BSFC, off the top of my head I don't see why the constant
    flow nozzles should be at a disadvantage. Maybe at idle, like you
    say but how much time do you spend at idle?

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.

It's not a problem on Wednesday at 10:30 am.  Saturday at 10:30 am is a
different story.  Start, warm up, taxi, hold, taxi, hold, taxi, hold,
taxi, run up, taxi, hold, taxi into position and hold, GO!

The solution, of course, is to have a low-flow meter of some sort.
Think about TWO lines to the injector, a small one and a big one.  You
cut the big one off for ground handling and just run on the small one.

Keith Wood

Do like Gordon says and lean the engine until you
are ready to go. No need for two fuel lines. Just pull the leaning
knob(s) to a predetermined position.
