Carb issues - Float bowl?

[Hicksi]

Hey,

Having trouble getting my '01 EC300 to idle.

Recently rebuilt the thing, only major differences from stock is a TrailTech Vapor and new full DEP pipe.

Upon kick starting the bike, i will get ignition and a couple of fires, but as soon as my foot hits the peg, the engine dies.
I have excess fuel leaking from the pipe header (which suggests my o-ring has also gone.) and some smoke.

Every time i attempt this i have to remove the plug due to flooding.

I have been fiddling with the throttle slide screw and pilot jet, although i wouldnt have thought this would actually stop the bike from running with me on the throttle?

Im going to whip off the back end and have a look at the carb float bowl as a freind suggested my float may be stuck?

Does anyone have any solutions?
