Can you remove the spark plug? Remove it, put a teaspoon of fuel direct into the spark plug hole, re-install the spark plug and see if it will start for a few seconds. If it does, carburetor is not getting fuel to the engine
Have to get to the carburetor, and check the fuel line to the carburetor for flow. If it has fuel to the carburetor, then the carburetor float bowl needs to be removed and the float and needle valve checked for flow from the tank. Bowl may be full if water or debris.
Either that or replace the carburetor! Sorry.
