I have ss exhaust and was told I didn't need it? I am just re-thinking this thing out could that be it?
Carefully trace the wire that is attached to the + post of the coil. It should go to the distributor and the points. It might go there directly or it might go there through the ignition switch. Because you have the battery connected with positive ground, you need to have that + post on the coil go to the points.

What do you know about that coil? Is it a true 6 volt coil? If you have a coil meant for 12 volts (with an internal resistor built in) and use it on 6 volts, it will give a very weak spark.

If you have an ohmmeter, read between the two posts on the coil with no wires connected. It should be closer to 1.5 ohms than it is to 3 ohms (12 volt coil).

There is nothing wrong with the Nu-rex modern points style upper plate.

Did you use the "gland rings" on the exhaust manifold when you installed it? They are a common source of vacuum leak.
