OK, so you have the Lean Burn system still intact, so in order to get the ignition to work, all the plug-ins need to be used and wired in the distributor, or, go get an older distributor to get rid of all the Lean Burn stuff, works a lot better, distributor will have some adjustment instead of the LB system adjusting it, along with a different carb, that carb is also LB and internally/electronically controlled and will get poor mileage if it isn't connected. LB was ahead of its time, but it doesn't last forever, when it goes bad, it is a replace system, not a repairable system.
Hopefully this makes sense, wire everything up, or get an older electronic ignition distributor to get it running, just wiring half the distributor is not the answer, which is your problem. The second set of wires goes to the computer (LB) to control extra timing advance/retard, this distributor has no mechanical advance.
Additionally, if the alternator has two field wire male terminals, if you follow the wiring diagram, it powers all the sensors on the intake manifold and then goes up to the positive side of the coil. If they are there, it charges, if they are not there, that extra field wire still needs to be connected to the positive on the coil or it won't charge. If you remove all the sensors, or don't power them or the Lean Burn, still have to run that wire to the positive on the coil. Follow the wiring diagram, took me an hour to trace it out (bad wiring diagram).
