@BALLSOUT - not always No 2 first....
The approved procedure for single engine taxi on the narrow body Airbus is to start ENG1 first. If you are then going to taxi on one engine the electric pump is switched on to pressurise the yellow system and the flaps are deployed. If you decide not to taxi on one engine (slot cnx etc) then you start No2, after starts and off you go.
On another note, I'd love to a picture of the underside of the 767's stabiliser!
