This works for me on the IO-550.

Cold start is: Mixture rich, throttle cracked, boost pump on, pressure
comes up, boost pump off, clear prop, crank

Hot start is the same except the boost pump is run much longer before
attempting to crank.

The only difference on mine is running the boost pump first with the
mixture at cut off to clear out the vapor in the lines. I have no
problems with a leaky distribution block.

This is a case where I think "old is better" with and ignition
switch/mags and a starter switch that are independent of each other.

Actually, hot starts are only an issue if you shut down, go away for
a while and try to start up (the worst case is your average fuel
stop). The thing starts right back up again if you crank it up
after it was running (good thing too if you run a tank dry).
