First off is the engine turning over?
If it is do you have spark?
If it’s turning over put the spark plug wires about a quarter inch away from the tips of the spark plugs to see if you have spark jumping the gap.
Does gas drip out of the carburetor after cranking it over and holding the choke closed. Usually gas will drip out of the carburetor after a half dozen or so revolutions with the choke pulled closed.
Let us know what you see after trying this.
