If you can get it to run even for a minute, then the following may fix it for you:
Go to your local auto parts store and get some Seafoam gas treatment (https://seafoamsales.com/small-engines/). Get a can of fresh gas while you are out. Mix some of the Seafoam into the gas that you buy.
Now drain all of the gas out of your lawn mower, and replace it with the new gas / seafoam mix.
Now crank your engine. If it will run for even a minute, the new gas / seafoam mix will have a chance to work its way through the fuel system, cleaning it of any gunk that is built up in there.
My lawn mower would run for just a moment, and it would then die. I did the above, and afterward my lawn mower ran like new. A year later, it is still running like new.

If you can't get your engine to run, then perhaps you could spray some Seafoam directly into the carburetor. That might get the engine running long enough to let the fresh gas / Seafoam mix work its way through the fuel system, cleaning it from any gunk that is in there.
