I am looking for some advise on the best way to start the engine when it is hot.

I am flying a Lancair with an IO-360.  The engine was built up by Performance Aero Engines in La Verne, CA.  It has the Airflow Performance FM-200 fuel injection system installed, it does not have a purge valve at the fuel distributor.  In addtion to the engine driven pump there is a single speed Dukes boost pump ahead of the engine pump.  The plane does not have a header tank so fuel is pulled directly from the wing tanks.  There are are check valves in the lines from each tank before the selector valve. 

Cold start works like a charm.
Prime: Throttle full open, prop high rpm, mixture full rich.  Boost pump on until see fuel pressure for a second or two then off.
Start: Throttle to 1/2", mixture idle cut-off.  "Clear" and crank.  Engine will catch on the first or second turn and I bring the mixture quickly to full rich. Throttle back to 1000 to 1200 rpm. Mixture adjust to keep lean for taxi.

I have tried a number of different ways to start the plane when it is hot.  Some work better than others but sometimes I think it depends on the phase of the moon.  I would really like to hear from anyone and everyone on how they go about a hot start.

Look for help.

Thanks

Ray
