It has fine-tuning screws located on the tops of the barrels, near the idle mixture screws, as well as large primary and secondary air correction jets located underneath. The discovery slide potentiometer and accelerator pump adjustment contextured slides permit the user to make precise adjustments using a flat-head screwdriver.
