OK, as you can tell, I am racking my brain trying to figure out what is going on with that mag plate you have purchased….
Spoke with Dan Anderson who was quick to point out that someone has pressed the driver coil windings onto the conventional universal mag laminations. Dan reminded me that the driver coils are held down with only two screws, these driver coils are held down with three…So, someone has used a conventional universal mag plate, removed the plug wires, installed the low tension wiring harness and pressed the driver coil windings onto conventional universal mag laminations…
I really don’t see how this could possibly work, but I am smart enough “never to say never”. You will know quickly when you install this set up and see what happens….
Dan also reminded me of a simple solution here….Now, you have the conventional mag plate, you could simply remove the driver coils, install conventional coils on this mag plate along with plug wires, remove the external coils, and use it as a universal OMC magneto, like found on the 1972 models…I’m pretty sure the flywheels are the same, but will look into that…
CORRECTION:
Just looked it up, the 73 models use a driver coil with three screws…Looks like the 72 and 73 mag plates supercede to the same number…So, will say that someone just added a second driver coil to the original mag plate…The flywheels are different between the two systems also…. So, we will wait to see if this set up actually produces spark on both cylinders…
