How many do a thorough postflight? It should take as long as the preflight.
I certainly don't, nor do I recall the matter ever being brought up by any of my instructors. Looking in the POH, there is nothing mentioned about post-flight checks or engine runs after landing, apart from the obvious stuff like securing the control wheel and retracting flaps. But I fly PA-28s and I guess it is a more involved procedure for complex aircraft?
