Default Starting 1978 cb125s, no spark. where to start?

I was all pumped, I got my battery in finally. I filled it, charged it, and installed it. Filled the tank with gas, hit the petcock, and kicked her over. About a hundred times...

The carb is getting gas, but the drain valve on the bottom of the float bowl is pissing gas. Also, I've got no spark. I pulled the plug and held it looking for spark, but I've got nothing. I even tried sticking a screwdriver into the plug wire boot, and there's nothing.

The coil was just replaced by me. It has a black wire that I connected to a black wire on the harness, and it also has a blue wire that hooks up to some kind of capacitor/condenser or something like that. The black wire has voltage when the ignition switch is on.

I'm not sure how to see if the coil is messed up or not. Is there a test I'm unaware of? If it's not the coil, then I'm not sure where to go from there. I have a wiring diagram, and it seems like everything is right.

sorry for the novel, I'm just wanting to get my *** out of the garage and onto the road.
