I need help. A neighbor boy acquired this bike and doesn't have the money to fix it. I volunteered to help. The bike looks like it is in fairly good condition but it need a bing carb or most of it any way and so far I can get any spark. I checked the tail lights and horn. Both seem OK. What else should I check. When can I find a wiring diagram for it also. I really would like the help this boy out. His family life isn't that great. Any help would be appreciated.
