Go to the auto parts store get some carb cleaner, take off the carb and spray it. The stuff is like gas wont hurt it a bit just follow the directions on the can.

You should remove the carb and take it apart to clean it. Grab a parts diagram from bikebandit or somewhere so you can see how it's assembled. Soak the jets for an hour or two in carb cleaner and clean all of the passages. I use a piece of coax cable with the outside stripped to clean out everything. The copper wire is soft enough that you shouldn't scratch anything if you're gentle. A stiff nylon bristle from a brush would be even safer.

Once everything is clean, check the gaskets and o-rings and replace if they're worn. Reassemble and ride.

Spraying carb cleaner in your carb will not work for anything other than regular grime during use.

If your carb is clogged like mine was from sitting all summer and the gas varnishing up, you will need to completely disassemble the carb. Let me tell you, it was easy. There is not a lot going on in there.
I bought the gallon jug of carb cleaner. You just put the parts in there and soak for a couple hours. They come out looking brand new. You may have to brush some spots, but I didn't.
I used a torch cleaning kit, the kind for oxy/acetylene torches, to clean out the jets. It was a world of difference.
Put it back together and BANG, it fired up on the first crank and idled like it was still on the showroom floor. My TRX250EX is almost like new again. I am so happy.

The carb cleaner spray is not going to get into areas that are dried and gummed up. In my carb it was the float valve that was actually stuck and would not move, so I wasn't getting any gas.

good luck!
