No need to use a jumper- - - -just remove the wire from the upstream side of the resistor and stack it on top of the bottom wire temporarily. That will put full battery voltage to the coil. Take the distributor cap off and tap the starter until the points open. You should see battery voltage at both coil terminals, the side terminal of the distributor, and the movable point. If that happens, change or clean the points. It's also possible that you've got a shorted condenser. With the points closed, you should get almost zero volts at the side terminal of the distributor. If you get more than a fraction of a volt at the side terminal of the distributor with the points closed, change the points.
