Alright, so my Dad came over today to lend a hand with the electrical. What I didn't notice before, because I wasn't reading the meter while turning it over, was that the battery voltage is dropping almost in half. Now that I know that, I can hear how slow the motor is turning. We jumped off my car's battery to a different ground, bypassing the tractor battery altogether, and everything changed. So I'm getting a lot of resistance through rusted/dirty connections, especially the main ground. Also, we noticed no ground out of the distributor, the points were corroded. After some light cleaning and the new, temporary, ground I was able to get a spark, but very weak. I'm still with you Soundguy on running the new wires, but either way I have to get a good ground. So next step is to go back to cleaning contacts and running new wires.
