I have been having starting problems with my 8n along with missing under load. Replacing the points, condenser, plugs, coil, rotor, cap, and rebuilding the carburetor did not help. At the latest refusal to start I checked the voltages and had 2 volts at the coil, 5 after the ignition switch, and 6.25 at the battery. Replacing the ignition switch seems to have solved the problem. I have had ignition switches not make contact before but this time it is high resistance.
