[QUOTE="aeviaanah, post: 253179, member: 6493"] rich is a term used to describe more fuel, lean is less fuel. if a motor is running lean it needs more fuel and you would turn the knob to the rich side. if the motor has too much fuel it would be considered rich, you would turn the knob to the lean side. the fast one is the adjustment for when you are traveling full speed and the slow one is for when the motor is idling. do adjustments on the water. try tightening the knobs (to the right) towards lean, all the way and back off 1 1/4 turn. you will notice the motor will die out for a second but will continue to run, this is known as a lean sneeze. when you have backed off the knob enough the sneeze will disappear. after the sneeze is gone, back off an additional 1/4 turn. this should be the new center adjustment, pop the knob out and reset to center, you can fine tune from there up or down. you will need to adjust idle during this procedure as well. adding or taking away fuel will change the initial idle setting. as you are making lean/rich adjustments keep adjusting idle to keep it at a desired rpm.
