I am in the process of converting my 1987 D15A3 (carbureted) to Crank-Fired Direct-Spark Ignition, using an Electromotive Ignition Controller and dual coil pack. Has anyone done such a conversion? I am certain I will have a lot of questions as I go along. To start with, how did you mount the Trigger Wheel, and more importantly, the Crank Sensor?
