Thanks for this information. Do you have some carburetor cleaning in a can, or some starting fluid. If so, spray a small burst directly into your carburetor, to see if your engine will start up briefly.
Customer: replied 2 years ago.
tried that already
Expert:  Donald replied 2 years ago.
Did your engine start up as you was trying it? Have you checked for spark to your spark plugs?

Are you saying that your engine will start now, but will not continue to run?

Thanks for this information. The fuel shut off solenoid on your carburetor could be faulty, or your carburetor may need a really good cleaning. If your fuel shut off solenoid is not working properly, your fuel will be restricted.
Make sure your choke is fully open, and your air filter is clean.
One of your safety switches could be faulty. A quick way to eliminate your safety switches as the problem, will be to remove your engine cover, and remove the kill wires from your ignition coils. If the sputtering continues, then your safety switches are okay. Remember that if your kill wires are not connection to your ignition coils, you will not be able to kill your engine by turning your key to off position.
