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.
Will carb cleaner fix a stuck float?

What does the float needle do in a carburetor?
The float valve uses a pointed needle against a square-edged seat, to give a positive shut-off. As the float relies on gravity, the chamber must be mounted vertically. Some designs, such as the SU, may allow a separate float chamber body to be adjusted relative to the carburettor to compensate for this.
Will seafoam unstick a float?
Seriously, try doing the seafoam again. It released gunk which jammed the float, so hit it with more to clean it up.
