Also it is not unusual for pilots not to know about the the need for 'pre heat' when the temp falls below a certain level.
You are absolutely correct in my experience. I forgot to mention in my previous post that, in Winter, it was a vital part of the morning starting procedure. Trying to get fuel from a carburettor, up through a vertical, cold induction tube on an 0-200 was extremely difficult, setting up a case for over priming and risk of fire which did actually happen before we established our current procedure. As far as I could see, nobody else did this even after watching our regular, instant engine start while they struggled to get theirs going.
