400EX Won't Start

ok guys, so i just got a 2013 400X a couple days ago, which is basically a 400ex with newer plastics. Anyways I was riding it a couple days ago and it was running PERFECT,then I came back and rinsed it off. After that it wouldn't start.. I'm not sure what it could be but I know it has to be something minor. Dried off electrical connections, changed spark plug, still won't start. The only way it starts is if i put the choke all the way on and hold the gas all the way in and then it sounds like sh*t. It sounds like a carb issue but I didn't fool with any of the screws and didn't get any water in the carb. I'm really stumped guys. Please help me out if you know the problem I was really planning on riding today! Thanks!
