Narrative:

Min taxi time from departure gate to departure end of runway 27L. #2 engine started during taxi and after start checklist completed. Before takeoff checklist flow was interrupted by cockpit conversation with both ground control and tower. When checklist was restarted 'flaps... XXX, green light, detent' was skipped. When throttles were advanced for takeoff, takeoff warning horn sounded. Flaps were then set to proper position for takeoff prior to takeoff roll. Takeoff was normal. Contributing factors include: min taxi time, checklist interruption and allowing ourselves to be rushed to avoid a delay in takeoff clearance.
