JW, are you sure that isn't a 6 volt gennie? They came with 6 volt systems originally. Someone could have put a 12 volt gennie on, but it would be more likely that they would use an alternator instead. Much simpler. If you have a 6 volt system and want to keep it, I recommend Steve with B&B circuits. He is the AC wiring Guru. He also has a magical way with generators and mags. He can get you the wiring diagram, and can sell you a new harness and all the components for a fair price.

Welcome to the forum! This place is a great resource for any repairs, parts, and advice you may need. It's also nice to hang out here. Good comfortable atmosphere.LOL!

I'm still starting mine with a 12 volt battery. Starter spins pretty darn fast! Starts up on the first time over, unless I flood it. If you still have the magneto(and i'm guessing you do if you can hand-crank it) you don't need a battery. I am fat and lazy, so I keep the battery and the starter going.LOL! I bought a new cheapo Wal-mart battery last year. I charged it once, and that was just because I felt I needed to. It was still spinning it over well. I wouldn't recommend spinning the starter for long periods at a time, as it may burn out the old windings. Make sure you clean everything well before you try to use the starter. Clean the brushes and the commutator ring with some very fine sandpaper to get the arcing and oxidation off. Make sure the brush shunts are not shorting to the casing. Check the start switch to make sure the contact points are clean, and no insulation has failed. Clean the stud on the switch and make sure you have a good heavy cable with good, crimped on ends. I recommend no smaller than #2 wire. Make sure you pull the starter and clean/sand the outside of the starter snout and the inside of the starter well. Tighten the starter up with the tapered pinch bolt. Clean the ground area very good. I used the bolt that holds the bottom of the throttle lever assembly. Make sure that is tight. Provided your starter is good, she should spin right over. I have mine negative ground. The 6 volt was p[ositive ground, meaning they were reversed. If you want to hook up your charging system, you may want to verify what your gennie is set up for before you start getting too far into it. Sorry I ramble on, I just try to think of what I went through and what worked and what didn't.
