Could you please explain your theory on how your going to get better fuel milage? The jets, needle, clip position, air screws are what control how much fuel gets dumped in to the engine. Do you really expect Acetone to change the amount of fuel that you go through? I wonder if acetone will break down the oil that u use for premix? Go put some acetone on a rag, put the rag on your face and lay down and drift in to lala land.
