How are you testing for spark? Save the info Bruce gave you for reference and get a copy of his 75 Tips. See the posit below yours and save a copy of that as well. You don't say but are you using the OEM 6V/POS GRN electrical system or are you attempting a 12V switch out job? Did you set the points correctly and set the timing correctly per the manuals? By 'starter switch' do you mean the pushbutton neutral safety starter button on the shifter cover? How did you determine it was bad as well as the roundcan cutout? Did you test the cutout per the I&T Manual? From our HOW-TO's has "WIRING PICTOGRAMS by JMOR". Download a copy for yourself as well. JMOR has done a great job showing every correct way to wire these old N's whether 6V or 12V. Doubtful if coil or condenser are bad, Coil can be tested static on VOM set to OHMS. Do you have the ballast resistor? The cutout is only used on the OEM 6V/system -if 12V it gets removed. Got the ESSENTIAL MANUALS? If not best to have them and read often.
