I am trying to replace the plug wire on my Huff Berry. I have read every thing posted and the PDF file sick Bike turned me on to when I bought the wire but it is all a no go. When I look into the CDI block there is a screw sticking out that the wire must screw onto but that just is not happening. I push and turn and do everything I have been told to do and the wire just pulls out in my hand. This bike has never started. The plug cap fell apart and parts went everywhere. I bought a new wire and still nothing. If I have to I will buy a brand new CDI but would really rather not. With this build it is buy, buy, buy. It should be a Huff Buy. How about some help?
