Have you checked to see what color your plug is? Does it backfire when you close the throttle or open it? Did you move the needle when you "adjust the carb"? If not, if you think it's too lean or plug says it is try lifting the needle (move the clip down a notch) see if it improves. How many notches are on your needle? try adjusting it on the needle until you notice a change for the better. You may need to rejet but tuning with the needle will give you a better indication as to which way you should go. Do a plug chop and post the results for the best advice.
