COP Ignition Development

I started to modify a lean burn distributor. Any distributor will work, but the lean burn has fewer parts to start with. The ignition works with a a shutter wheel locked to distributor shaft. The pickup is an optical vane sensor, but that will be covered later.

The first step was to disassemble reluctor top hat from distributor shaft. There is a wire type c-clip with tabs in the well below the rotor. Needle nose pliers are used to grab a tab, and pull it out. The reluctor is located on shaft with a roll pin, and a slight friction fit. I got my finger tips at the bottom, thumbs at top and pulled it off the shaft. The base is mounted with two screws, remove those and lift plate. Keep the plate, the optical sensor will be mounted on it.

The modification process is simple, and could even be easier if the coupler was a manufactured part. I started with a 1/2" long, 5/8" OD aluminum rod stock, with a 5/16" ID. A 6-32 setscrew was added to fasten to distributor shaft. A single lathe cut was made to fit the ID of shutter wheel, a press and 5/16 bolt was used for crimp. The setscrew is aligned to a wheel notch, for ease of assembly.
