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.
