Hi, Im brand new to the forum. I bought a 49 cc zstar 2 stroke pocket bike as a project for my son. It has a pull start only. I am not getting any spark when i pull the pull start and ground the plug out to the frame. Does anyone have a manual for this bike or can tell me how the wiring should go so i can troubleshoot this. Would hate to replace anything if i dont have to. Thanks in advance.
