I can move the choke lever by hand, it seems like the Carb has an automatic choke but it doesn't have any wires hooked up to it. What do u think?

Chug,

Yes, that's an electric choke, and it's useless without power to it. The power usually comes from an oil activated pressure switch.

So that's certainly part of your startup problems. Fix that, then go from there.

Lower passenger side of the block.

Looks like this, except this is a V8 and it's in a different location.

Find the other ends of the 2 red wires. One should connect to the choke.

Going off memory, the purple one is your oil pressure sender.

So the red wire that doesn't connect to the carb is the one I split into?

One of the wires coming off the switch (red w/white stripe), should connect to the choke. The other is for the manifold heater.

Again, gong on memory, here, so someone please correct me, if I'm wrong.

Dude, crack your service manual open, and review the wiring diagram.

I'm quite sure the oil pressure switch supplies both the manifold heater and the choke with power once the oil reaches pressure. So one of the wires goes to the choke, and other goes to the manifold heater. It probably doesn't matter which one goes to which.

Short of hooking it up for you, I can't do much more....
