Anyone remember the non-limited flywheel positioning at TDC? leading edge of magnet at leading edge coil @ tdc?? thk, Adam

It should be at the point where the poles of the magnet leave the armature of the coil?

I've read about timing 2 different ways to do this. 1 was with a timing light and another with setting flywheel up like on the 3120 deal with 272 coil. I cant find the pic yet, but sent the timing light light way in PM.

Thanks! Never tried the timing light method. I've used the method where the edge of the second coil pole is placed at the edge of the departing magnet (flywheel) at least that's what I remembered from 5-6 years ago. I degree'd the movement from where the flywheel magnet is centered on the coil poles and it moves 28 degrees til the magnet departs the edge of the coil. Would the point where the edge of the departing flywheel magnet be the point where the field collapses and spark occurs?

I read through the theory of how the ignition works. I have one question.

To turn on the darlington it uses one volt to forward bias it and allow current flow for the secondary.

So to turn off the darlington it uses another one volt. My question, is this a negative one volt to reverse bias the darlington and shutting it off?
