If it's still running on 6 volts, it needs a 6 volt, 1.5 ohm coil
If it's been converted to 12 volt, it needs either a true 12v 3 ohm coil, or a combination of a 6v coil and a 1.5 ohm resistor.
This can be a tricky area, purchases made carefully, know what you are ordering and verify what you are actually sold. Can't depend on the parts store technician to sell the right parts because this is old school technology, they can't poke it up on the computer!
Then there is the aftermarket parts quality issue. Very hard to find reliable ignition parts now. Stay with the name brands if possible, but even those are notorious for being bad out of the box.
One other consideration would be a Pertronix electronic conversion. But still be sure it has the correct coil or coil/resistor or even that will be short lived.
Also look at the condition of the distributor. If there is any side play in the shaft, the points will not stay set and will be short lived. The electronic kits are more forgiving of a worn distributor. Still there is a limit, and the centrifugal advance needs to be free and functioning to run properly.

But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
