Have you checked every ground wire you can see in the engine bay are they tight?
Have you made sure all the positive are tight. Loose grounds on the carb can kill you
ok here's what we did we ran the hot wire to the alternator nice big thick cable.
had the battery ground hooked up. turned the key to the start position aka ON
we then had a wire from the positive coil to the battery.
now there is a wire that goes to your starter that is just for starting this wire I took and I unplugged it from the set up it was hooked to put a longer wire in it and held it in my hand and touched it to the battery violia rig fired right up
To turn it off simply turn the key off or pull the coil wire.
Turning the key off is much easier.
If you see a flaw in what I remember please chime in and correct me.

So be careful, look up a simple starting diagram on the web call a buddy that knows a whole lot about cars. I can look at the wires in my engine bay since we have ripped out every other wire but those needed to start it up. This may take me until after sunday since my rig is an hour away from me in a shop.
