"Turning it up a flat" refers to adjusting the fuel flow screw inside the injection pump. It is an allen screw, and "a flat" refers to the 6 flat sides of an allen wrench.

1 "flat" = 1/6 of a turn = 60 degrees of rotation.

Here's a good article explaining how to do it, step-by-step, with pictures even.....
