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.
Im guessing this is a petrol lawnmower. sounds like the float is not set at the correct level in the carburetor
If it is a petrol lawnmower made in China there are now spares available

Can't get answer from Tesco and Wikipidea doesn't know - Note to self... do not buy a Tesco branded Petrol lawnmover in future.
Dump/siphon/drain it as best as possible and as long as you haven't tried to run it, you should be able to fill it with petrol and fire it up! The petrol will dilute the residue sufficiently.
A full tank of petrol is worth as much as a full tank of petrol in any other car.

did you clean the air filter? is there enough petrol? is the string or attached spring broken? do you have a choke?
Yes - Oil is lighter than water. Petrol, or gasoline, floats on water because it is lighter that water.
