Along with what everyone else has said:
When you get the engine freed up, you may want to think about the following...
Soak the carb in carb cleaner for a while. A rebuild kit wouldn't hurt anything, either. I was sorry that I didn't rebuild mine when I cleaned it up.
Drain any gas that's left in the tank. Make sure that you're in a well ventilated spot. It's gonna stink.
You may want to replace your ignition parts, too. It's good insurance against aneurysms.
