Default 1970 Ignition Question

I am getting my 1970, 454, 4-speed car started after it sat for decades. The steering column had a stripped gear, so I tore it apart, replaced the gear and replace the ignition switch as a safeguard. Lars did the carb, worked through all the distributor setting/wires to make sure all is good. The car will fire and run pretty good, BUT it will turn off once I let the key go back to the RUN position (it will only run in the START position). I did not want to harm the starter, so I stopped and am seeking help.

Thoughts on where I may have missed something? Is the rod going into the ignition switch a bit off?? I know the ignition switch can move a bit forward or back, so I was thinking this could be the issue.

Thank you for the help!

Sounds like the resistance wire or ignition switch is bad. Coil gets full battery volts during crank and then switches to about 9 volts in the run position.

There are 2 wires that go to the + post on the coil. One comes from the starter and has 12V only in start.
The other comes from the ignition switch and has ~9V power anytime the key is on.
That's where you check.
