Has it got pressure in the crankcase? If your not building crank pressure then fuel won't flow from under the piston through the transfer ports and then into the combustion chamber. If the engine has reed valves check for a cracked or broken reed pedal. If not, look towards your crank seals or a crack in the intake boot/carb insulator.
spark plug oily?
clean it up with sandpaper

maybe its fooded
Clean the carb, replace the plug(s), check your ignition timing,

If it doesn't start after that, then there is something wrong with the laws of physics.
