Well if you hit the gas (full throttle) from a complete stand still and a bunch of smoke comes out the muffler then you are to rich. Just adjust the the needles till you get the responce that you want on the low end. Then adjust the idle needle so that it will idle good and not stall on you. Just also remember to make sure that it dont overheat. If it over heats then you need to adjust it so that it dont over heat. sry if there are many mistakes in this and its hard to read its just me
