It is a simple red button to ground the magneto and I have never done this before. I will probably choke it out in the meantime. I do not think I can kill it with the clutch because the clutch only expands from spinning. I have not yet started this up and will probably do so at midnight unless some sould cares to save me? I am also uploading a virgin image for you to instruct me if need be. What wire goes where and what to ground. Please help and I will do my best to ride off into the sunset and move on to the Bike Bug I am expecting. Thanks! I will take some pic tomorrow if I get this squared away.
