need major help

Hey I just got an 04 grizzly 450, first night I took it out I noticed that the air box was not sealed. flooded the bike even tho it is snorkeled. got it fixed and decided to do a carburetor rebuild kit. I think I made a mistake bike wont idle and if I accelerate it the bike bogs and shuts off, think it could be the air fuel mixture screw on the bottom of the carb motor side, but Im not sure. Can anybody help out was planning on going out tomorrow morning.???
