u need a manual with the electrics specs, start from top to bottom of the path of electric to see where its comin from and going to wityh a multi meter is it coming out the stator when turned over is the pulser coil emitting a charge when the magnito spins, is there any power coming out the cdi unit to the coil?
have u tried taking the plug cap off and cutting 10 mm off the ht lead and screwing the cap back on to the ht lead, the inner conductor wirres can rot away just leavin the rubber outer
the problems there just needs finding, by pass the ignition switch and disconect the kuill switch see if that helps
