Bad battery, worn out starter, bad battery cables. Using an 8 volt battery is just a bandaid for not having cared for the starter and the starter circuit. When the worn out brushes and bearings in the starter take 8 volts at the battery to overcome bad connections and wimpy battery cables, it goes on down hill.
A 6 volt generator with a regulator won't properly charge the 8 volt battery either.
Basically it needs (and my 8N needed that nearly 30 years ago) the starter cleaned up with new brushes, a turned commutator, and new bearings (just sleeve bushings in the 8N). It needs FAT battery cable and ground strap with clean connections. Nothing from Walmart's battery kiosk is appropriate for a 6 volt system. Then it needs a good 6 volt battery and probably similar attention to the generator. On the 8N that I had, most of the wiring was shorted out from the insulation having rotted off and the wiring running through that conduit over the engine.
It will start and run fine on 6 volts, but it takes care and good wiring to get there. Battery post and all starter circuit connections need to be clean. These days, I'm applying a bit of silicone dielectric ignition grease to such connections out in the weather to keep that weather out and its making them last a lot longer between cleaning tasks.
