flooding BAAAAAAAD

[scooter]

Evo 150. On the way home today it sputtered some. About a mile later it wouldn't idle, had to keep it revved at the light. About 2 minutes later it died and I was done. Fuel was pouring out of the overflow, the one that has a 45 degree slash cut in it. Anyway, so while I'm waiting for my boy to come get me in my truck I did the following.
Pulled intake tube from air box- full of fuel.
Tested vacuum petcock- good. No fuel until cranking
Pulled spark plug and blew all fuel out of combustion chamber
Cranked with plug hooked to coil and got spark; cleaned plug
Pulled slide diaphragm apart, checked it, appears normal although it was inside out
Got home, drilled bowl screws out, nothing obvious wrong and didn't have a sticking needle/float which I thought would be the problem. Of course maybe I jarred it loose getting it off the scooter.
Just get new carb?
