So for the past year I’ve been working on my 3a to turn it into a vintage wheeler. It ran a year ago on a 12v battery but that fried my old starter. I’m positive the vehicle is 6v because it has a generator, are there any other indications that would prove it’s a 6v Jeep?

Since using the 6v battery and trying to get it to run I have replaced, spark plugs, plug wires, cap, rotor, points, condenser, starter, solenoid, engine to frame ground strap and ign coil. It has a new fuel pump, the carb is rebuilt, and the battery is g

I have fuel, air, and spark and I’ve only gotten the engine to run for a few seconds twice. What am I missing?

I’m going to check my timing tomorrow because that’s the last thing I haven’t checked, but I don’t think I’ve done anything that would have altered it since it ran before.

Thanks for reading!
