Turn them both in until they just seat. Not too tight or you'll damage the needles! Turn both out 1-1/2 turns. The engine should start at that setting. Allow it to warm up for about 3 minutes. Start with the bottom screw and the engine set at fast speed. Turn the bottom screw in slowly until the engine starts to run rough, then counting the turns, turn it out slowly until it starts to run rough again. Then turn it back in half way between the rich and lean settings. Then set the engine at idle and do the same process with the screw on the side of the carb.
