I have a question on the predator fuel curve. It is labeled rich to the left and lean to the right. When you move it to the rich side (to the left), the percentage goes negative, which I would think is reducing the amount of fuel. Shouldn't the percentage be positive (increasing) if I'm adding more fuel? Is the predator just labeled backwards? I would hate to be decreasing the fuel to the motor instead of increasing it because the label is backwards.
