B floats are prone to contacting the side of the bowl if they get bent. The rebuild instructions warn of this.
The old 'hit the carb with a hammer' trick is commonly used to temporarily fix this problem until you have time to fix it right.
This might explain why the problem came and went on its own. For now anyway.
