Installed distributor - Now it makes a bad noise

Hey sorry for not keeping up on this post. I got really sick. Anyway. I got a video of whats happening. just to catch everyone up...

What i have done
- Installed new distributor (I think the pickup on the old one was bad but the whole thing was rusty and gross)
- Confirmed TDC using a chopstick through the spark plug hole (thats all i got right now) and turning it over by hand. Yes it is on the compression stroke.
- Made sure that the distributor is in about 8 degrees before TDC.
- Wires are in the correct order/location on the cap.

Symptoms
- bucking/grinding when it seems like it should be firing. It sounds like the starter fighting the flywheel to me.
- this problem only happens when I'm sending spark to the plugs. If I ground out the ignition coil or otherwise disable the ignition it turns over just fine.

Thanks. This is driving me bonkers. I'm worried I've done something colossally stupid and havent't noticed.
