You need to see if any gas comes out of them first.
That said the carbs are the silver metal blob suspended in between the engine and air box by some rubber tubes similar to toilet paper rolls and on the other end some rubber tubes that flatten out and connect to a black plastic box.

Don't remove them yet, they are a big huge pain in the **** to put back in. So let me get home and take some pics of draining the float bowls so you can see what Im talking about. I'm not sure I can explain it without you knowing anything about what they look like or do first.

What you do next depends on how much gas comes out. Then you can decide if your up to pulling the carbs or not, it may be better to take it to the dealer. It should only be an hours labor charge (unless they suck) which should be about $60.

Try the simple stuff first and draining the float bowls is something you should learn anyway.

 

I found this Click Here. Drain your carbs and see how much gas is in them then report back.

 

That guide looks great. The pictures really helps. I will try it when I get home today.
