Will fire once per plug then immediately dies...Help?

Let me give you the background:
Last week I replaced my throttle cable and also re-welded a tab on the front of my frame. Now, I took it out on Saturday and it started fine, it felt great, had good power, and I rode it about 3 minutes and it died after going up a hill. 3 things happened before it died
(a) I went through a puddle at the bottom of the hill, but the air filter was totally dry,
(b) My rear brake caliper slipped off the frame guides and was pulled tight so that it was biting against the rotor
(c) and then it felt like someone shut off my fuel.
I reattached the caliper and have tried 2 plugs. Now when I kick it it will fire once per plug and then immediately die, like I have no fuel of someone is holding down the kill switch.
The original plug i pulled out was fouled. The brake seems like it would have something to do with this but it was running fine up to when it died. I removed my electronic box before I welded on it.

Any help would be greatly appreciated.

When I welded the frame I only removed the CDI (i think that's what it is called) the box on the front of the frame. But again it did run for a while after the weld.

This time when I went to kick it over, gas started peeing from the bottom of the carb. I've got the carb apart...do I just poke around on the bottom of the carb and hope whatever it was comes loose? It started leaking one time before and i banged it around and it stopped.
What exactly am I looking for when i've got it all apart?

One of the little screws that holds the bottom on is stripped so im going to go remove that.

I've also removed the kill switch to ensure that is not it.
