Here's my cold and hot start procedure. Works without fail unless I have a brain fart and do something else (it happens). Cold Start: Crack the throttle (1/4" on quadrant), boost pump on, open mixture for 5 seconds (or more) and close mixture. Crank until it fires and smoothly open mixture. If it doesn't fire after 1 or 2 prop turns, stop cranking, open mixture for a couple more seconds, close and crank. Can't remember having to ever repeat that again. (Rather than the 5 seconds, watching the fuel flow meter while the mixture is open is more effective. Just open until the fuel flow goes up and then stabilizes. Then close and start. No 2nd tries required when following this method). Hot Start: Crack throttle, boost pump on, crank. Can takes 3 or 4 turns until it starts to fire, roughly. Smoothly open mixture. All movements are smooth. I only open mixture to the position slightly richer than I use for taxi, then once started, I lean it to my normal taxi setting (and LOP setting). If the throttle isn't cracked, neither method results in a start. I don't touch throttle until it starts, then I simply try to keep it around 1000rpms I do a fair number of hot starts - landing at home and filling up before taxi to hangar (definite hot start). Or, taxi to fill-up before taking off (not sure that qualifies but I use the hot start procedure). My home base is in Durham NC, so the ambient temps can be sky high. I'm not sure exactly who gave me these instructions. Might have been in the Van's doc but whatever... I've never been able to figure out what the big deal is with hot starts. This is my first fuel injected engine. Bill > [b] Works for me too. Simple. -------- Wayne G.
