Lets parse the question. "Run up" is kind of vague. Lets ask "Do you run the full checklist or the alternate checklist?" Example: the kid brother of a friend made an intermediate stop 30 miles short of destination in a Barron to drop off one passenger. He was in a big hurry and no checklist. He made a fast turn onto the active while pushing the throttles open. Intersection T.O. Rotated early due to less than full runway. It was then that he realized he was still on AUX tanks (they were pretty low). Number one quit while rotating. And everyone here knows why. Whats amazing is everyone lived. Barron destroyed.
