flooding

my 07 800 floods out when it sits. It is really hard to start and When I finally get it to start is spews fuel out the pipe. Is it in the fuel pump or in the carbs? I seem to remember when I turn the fuel line off it still does it. MAybe its a bad diaphram..or sticky floats... Any Ideas?

2007 M8 PG Turbo, Attitude control box, 9 lbs of boost, Avgas I went riding last Saturday, had a great ride, machine was running great. Probably put 20-30 miles starting and stopping the sled plenty, shutting on and off before I pulled up to the group, let the machine idle down, and then shut...
