just bought one of the japan cdi kit for my 85 atc70. but no instructions with it. i obviously know where the stator plate goes. no idea where the little black box goes and do i use a regular 6v coil. if someone could point me to a website or help me in anyway. the reason im using cdi is because could not get plug to fire. tried 2 new coils,2 set points, 2 new condensors and new spangler ignition kit. i am not a rookie working on these hondas, been working on them for 40 years never had one that could not get to fire eventually! ive owned 6 of these atc70 never had this problem. THANX TRAMO
