It is just above the injector lines. You wind it IN towards the engine to increase fuel, start off in small increments as every pump is different. You really do need an EGT gauge to monitor and give you an idea of what is happening.

I highlighted my original position with a white paint marker and a blade before making any adjustments.
Here's a pic;
