Cough
If I remember correctly...(737 classic...)
By classic you mean 3/4/500?
On the B737-200 it was the same procedure, But you had to also open the right engine spar valve, or you got no fuel to the defuel valve. The easiest way to open the spar valve was to trip the ignitor CBs, then open the fuel lever on the pedestal (HP cock). Then you forgot to reset the CBs, and the engine would not start.
