So, update for today. Would not start this morning. 95% of the cranking was nothing, and a small cough once in a while. Had to get a ride to work. Got home tonight and tried again, pretty much the same. I was talking with a friend of mine and he told me to hold it wide open while cranking. That almost got it going, but fell short. He asked if it smelled like anything so I smelled the exhaust and I smelled gas. Tried cranking again wide open, and it backfired like a gunshot out the exhaust. That brought up the question of timing. I pulled the cap of the distributor and it was extremely corroded. I pulled the rotor off and the end of it was broken clean off. Luckily the brass contact that fell off the end was laying there. I used a rubber band to strap the brass piece back down and wire brushed all the contacts. Put the cap on, and so much as breathed on the key and it fired up beautifully. It revved clean and responsively. I shut it off to see if it would do it again, and it fired right back up. Needless to say I'm going to buy a rotor ASAP, and maybe the cap depending on the price. I don't think it really needs replaced.

I'll be getting a coil as well, but I want to leave the old one on and see if the rotor fixed all my issues. I'll have the new one with me in case.

I thought you had replaced the cap and rotor. That can cause a coil to arc. It might be the end of it but not always. You definitely need to replace the cap and rotor. It should NOT be corroded. Personally, I go with brass or copper as aluminum is prone to a thin film of corrosion.
