The resistance reading is really only a rough indication of the coil's state, as it depends on the wire diameter and length of wire used in the winding, so if the coil has been wound with finer wire, more will be used, so resistance will be higher than if a thicker wire was used. I think the problem is, unless you have more sophisticated measuring equipment, it is not easy to say that a coil is out of spec (short circuit or open circuit are probably a different matter

) Have you measured the output of the coil (volts ac) on kick-over? You should get a good 'kick' on even a cheap meter with the leads disconnected from the loom.
