How do you free a stuck float valve?

How do I know if my carburetor float is stuck?
One of the signs that the carburetor float is sticking is when the engine will not idle. The float is not letting enough fuel into the reservoir, allowing for a constant idle of the engine. The carburetor float is stuck in the closed position, and only a small amount of fuel is seeping into the reservoir.
What happens if carb float is stuck?
If the floats are stuck down, fuel will overflow out of the carb. If the floats are stuck up, no fuel will enter the carb bowl.

What happens if carburetor float is too high?
In an extreme case, if the floats are set too high, fuel will overflow via drillings inside the carb body. In addition, fuel may flow into the engine unrestricted, which, if the engine is not running, can cause hydraulic lock – that is, as the piston rises on the compression stroke it cannot compress the fuel.
What causes carburetor to overflow?
When the tip of the valve becomes worn or debris prevents the closing of the valve, fuel flows continuously into the bowl thus flooding the engine. Under severe conditions gas may soak the air filter or overflow out of the carburetor and onto the ground while parked.
