If you're trying to find the default method that comes with the installation, you're looking for it like such:
function action_404()
Opposed to
function 404()
This should also be in your fuel/app/classes/controller/welcome.php file.
The "action_" prefix should be attached to every function that is executable through the HMVC. Read more on the documentation here: http://fuelphp.com/docs/general/controllers/base.html
Not sure if this was what you are looking for, but hopefully it helps.
