A 6 volt coil, used with no resistor, in the system should test around 2 +/- ohms across the two threaded screws on top. This is the resistance of the wire in the primary windings, there is not a separate resistor in the coil, the windings are the resistance. It is unlikely that the coil has 0.0 primary resistance since this would create a direct short to ground when the points are closed. This would blow a fuse or burn up the wires without a fuse in the circuit. If you don't have a blown fuse or burnt wires then perhaps you have a resister in the circuit. The resistor could prevent the coil from working unless the coil is intended for use on 6 volts with a resistor. The resistance from the center terminal of the coil to either of the threaded terminals should be in the range of 6 +/- kohms (6,000 ohms).
In answer to your question is the coil bad; I cannot not tell from your measurements. I would suggest that you first, determine that you have have power (6 volts) to the distributor terminal with the points open. With points closed the distributer terminal should become ground (connected to ground).

Today's Featured Article - Earthmaster Project Progress Just a little update on my Earthmaster......it's back from the dead! I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
