318 Engine stumble

I will get more pictures of it.
And pictures of what the gap looks like when it’s at its highest point set at .017

What would the outcome of such a small dwell cause?
The points would not stay closed enough to sufficiently charge the coil.......causing a weak spark?

And too much dwell keeps them closed too long. When They are not open long enough it affects the time allowed for the magnetic field collapse into the secondary windings. Not giving it enough time to collapse and generates a weaker spark?
