A needle can be made to float on very still water.
Yes, you can float a needle I have done it before. It doesn't have to do with density though it has to do with surface tension.
On some liquids it will float, on others it will not.
A needle can float on water due to surface tension. When the needle is carefully placed on the surface of the water, its weight is not enough to break the surface tension created by the water molecules, causing it to float.
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.
in relation to solids or liquids in liquids: Density. A lighter density compound/liquid will float in a heavier density liquid
I would suspect a bad needle valve and seat in the carburetor. The float level can also be set too high. I would replace the needle valve and seat and check float level.I would suspect a bad needle valve and seat in the carburetor. The float level can also be set too high.

Hot liquids have lower density than cooler liquids because the heat causes the molecules to spread out, making them less dense. This difference in density causes the hot liquid to float above the cool liquid because objects with lower density float on top of objects with higher density.
It is in the float chamber of the carburetor.
A needle placed in water will float due to surface tension. The surface tension of water allows the needle to be supported on the surface rather than sink.
Yes, a needle can float on water if it is carefully placed on the surface due to surface tension. However, if the needle is pushed down into the water, it will sink due to its density being greater than that of water.
To replace the float needle and seat on a Tecumseh carburetor, first, remove the carburetor from the engine and disassemble it by taking off the float chamber. Carefully detach the float by removing the pin that holds it in place, then take out the old needle and seat. Install the new seat by pressing it into the carburetor body, then attach the new needle to the float and reassemble the carburetor, ensuring all components are properly aligned and secured before reinstalling it on the engine.
