I have a 1984 dt50 with electric start. It doesn't get spark to the top plug only.We have changed the wiring at the coil and it fires then cdi and it fires but when we change it at the stator it will not fire.I believe that something is wrong with the stator or could it be the cdi? I have attached a chart to test the cdi but i am not sure how to use it. cdi chart (wecompress.com).jpg
