Did you use a point file to clean the points? Did you remove the front mount distributor to work on it? Did you set point gap to .015" and set/check the timing per manuals? We now know you have a 12V battery. Don't assume just because it is new it is good. They can be junk out the door, especially the cheaper brands. Have it tested at a starter shop or auto parts store -it usually doesn't cost anything to test. Is your coil 6V or 12V? Note the last PICTOGRAM shown in my prior post. It is a 9N/2N for a 12V system with front mount. Trace the additional external 1-OHM resistor. You need to add that if your coil is 6V. Delete if coil is 12V. You do need the OEM Ballast Resistor in the circuit and delete the OEM roundcan cutout. Spark test per '75 Tips for N-Owners' by Bruce(VA or a commercial spark tester will work. Carb is fine -just perform the fuel flow test. Don't go by if you can or can't smell gas. Set a coffee can under the carb. Loosen the 7/16" nut on the fuel line at the carb inlet and point line into can. Open the Fuel Sediment Bulb Valve 2 Full Turns. Observe fuel flow is a steady stream and you fill the can with 1 pint in 2 minutes. Any hesitation or failure to fill indicates problem is upstream on the bulb or gas tank. Test passes? Connect line and repeat using the carb drain plug in bottom. Passes? leave it and move on -it's electrical. 90% of all non-staring issues are due to incorrect wiring regardless if 6V or 12V. So, again, reference the PICTOGRAM to verify wiring is all correct, exactly as shown, no shortcuts or skipped steps.
