I have been having a problem lately with engines on some aircraft not starting or if they are already running and I shut them down they wont restart. I tried resetting all failures, loading the default 172, saving that flight, shutting down FSX, and restarting with the default 172 with all switches on. All is fine until I switch to another prop driven aircraft then then engines wont start. I did make sure that mixture was open, mags were on, fuel tank valves set correctly, etc. If I load the default 172 and start the engine then switch to another piston plane then all is fine and the engines are running until I close the mixture and let the prop stop. Once I try to restart it only cranks but wont fire up. Any ideas on how to fix this bug? It affects a number of different aircraft.
