Two Times Can't be a Coincidence...Dart not Firing

You know ,the distributor and magnetic pickup are both used, plucked out of a shed and given to me. Any way to test that magnetic pickup to see if it is bad?

Small update. Timing was shown to be about 20-25 BTDC (yikes!). Got it back up to about 10 BTDC and tightened it up there. My misfiring is gone, the idle has improved greatly, and if I left the car shut down for a few minutes it would start much easier than before. Took a short drive up and down the street, restarting the engine multiple times. So far, so good. Next little 'baby step' is to the gas station.

Ahhh....I remember trying to convinced myself i solved the problem too. Lol. ask yourself why an advanced timing setting seems like it caused a complete lack of spark? Fyi....my distributor is LOCKED at 40....and I can still start the car without a starter assist...
