[QUOTE="bassboy1, post: 38852, member: 55"] The knob is a idle speed, or lean rich adjustment. It is connected to the needle valve in the carb, and adjusts the amount of air that mixes with the fuel in the combustion chamber. You need to idle the motor, then when warm, mess with this knob till the motor sounds like it is running the smoothest. May need to pull the linkage from the knob, and manually move the needle valve by hand, as it will go farther than the knob will. General rule of thumb is to start by turning it all the way in, then backing it out 1.5 turns. Then, hook up the linkage, and fine tune it from there. I can't see real well where the lube is coming from. Could you take it to MS paint or something and highlight the oil line with a brighter color? [/QUOTE]
