As mentioned you need to do alot of prep work before cranking off. Get a parts list or access on this site.
If some wiring is bad, it probably is a real issue, don't want to burn it to the ground prematurely. Fuel vapors and sparks don't get along. I'd disconnect everything that I didn't need to start the engine, ring out those you do and rewire the bad ones in engine bay before starting. The old cloth insulation will "toast" and fall off leaving bare wires.
If you jumped the starter selenoid correctly (observed pos. ground polarity) and it spun but did not engage the flywheel, the "bendix" is either stuck or broke. If it ran backward, it's not jumped right or winding issues. Need to pull and bench the starter to check. The carb starter circuit only impacts the key ignition - makes wire hot to the selenoid. It is an open circuit past the carb contacts, no impact. It's not making anything hot on that side in reverse either and likely not to pass current through it the way they work.
ps: Sitting in the desert most all the seals will be toast. Check and clean fuel system for dirt/old gas residue and rebuild the carb & fuel pump. No gain starting as is and plugging up worse or it won't run leading to false conclusions. I recently got a carb from the desert and it was full of dust and gaskets were toast.
