1. Set the low & high end needled to about 1 - 1 1/2 turns each.
2. Choke the carb and prime it until it's wet. 3. Fire up the engine and let it warm completely up for several minutes. Then let's set the top end first as it is the easiest of the two. Go to full throttle. Adjust the top end needle for peak RPM. Leave it wide open for about a minute to see if there is any change. Should the engine go lean, open the low end needle slightly. If this does not work, you will have to adjust the needle valve inside the carb (I will explain this later). If the top end runs OK, then slowly pull the throttle down until the engine begins to "four cycle" and hold the throttle there. Adjust the low end needle until the "four cycling" stops. Now lower the needle until it "four cycles" again and adjust the low end again. Continue doing this until you reach full idle. Now, from full idle begin to throttle up until the engine begins to bog or hesitate. Open up the top end needle just enough to stop the bogging or hesitation. When this is done right, you will be able to set the throttle in any position and it won't "four cycle". Plus you will be able to transition from idle to full throttle without any hesitation at all.
