"Floating Valves" refers to a condition in which the valve-springs fail to fully close the valves, allowing them to "float" during the stroke cycle. Floating valves can result in valve-piston contact with consequent catastrophic mechanical damage. This is caused by revving the engine past it's red-line, or the maximum RPMs the engine was designed to run.

What is the technical reason for using two inlet valves instead of one big inlet valve?

If you are referring to intake valves on an engine the engineers use two valves to get a larger valve opening with reduced weight so you can achieve higher rpm without valve float. valve float occurs when a engine spins so fast the valve spring can't keep the valve in contact with the lifter or the cam lobe causing the valve to float.

The float on your lawnmower is full of petrol?

The float bowl is supposed to be full of fuel. However, if what you are saying is that the fuel doesn't stop flowing into the float bowl and causes the engine to flood, then the problem lies in the needle valve that is controlled by the float. When the float drops because the engine is "pulling" fuel, the valve will open to allow more fuel into the bowl. As the bowl fills up, the float will rise and close the valve to cut off the fuel supply. The other interpretation I can make of your question is that the float itself is full of fuel. If that's the case, the float is damaged and must be replaced.
