Needle floats if u place it on the surface of the water even its density is heavier than water because there is a thin film on the water surface that is stretched towards the sides of the container because of the collision force of the molecules & this is called suface tension when u plae the needle vertically it tears the film therefore it sinks

Why gas come from carburetor after you shut down?
The problem is most likely in the float bowl. The float could be bad. The likely cause is the needle valve that is control by the float is stuck, or dirt has gotten between the needle and needle seat. This is an easy fix. Carefully remove the float bowl. The float will be held in place by a pin. Remove the pin, and float. Check that there is no fuel in the float, and that it floats in gas, if not replace. The needle valve will come out with the float, as they are connected by a wire link. Make sure needle vale is clean, and able to move freely inside it's housing. Check the bottom of the housing at the needle seat to make sure it is clean of dirt. Reassemble, and you should be ready to go.
