HELP. Won't start after checking jetting.
 

So, I have a yfz450 that has been missing and cutting out on the top end so I checked the jetting. After putting it back together the carb leaked pretty bad, I ordered new o-rings and diaphragm. After putting them in it stopped the leak but it won't start.

It wont turn over or anything. Acts like a dead battery. I push started it and it started quickly and after 30 min of driving I killed it but same thing, won't even try.

Something I thought was odd is the neutral light will come on as long as you hold down the start button but will not stay on after you release.

The guy I bought it from had one of those clip on kill switches on it. I took that off to get it out of the loop but, didnt help. Is there any electrical on the carb I could of knocked off that would cause this?
