there are several carb adjustments you can make to richen it up. first look at the needle and clip, it is easly loacated if you take the top of the carb off. then move the clip down on the needle,thus raising the needle up allowing more fuel to pass by. if that doesn't do it then you will have to get a larger main jet.
good luck,
