Hello and welcome to Just Answer,
Clean the spark plug and dry it off. Before you put the spark plug in it put a couple of tablespoons of gasoline into the spark plug hole. Put the spark plug back in it and then try to start it. If it start up and then stops then you likely have a plugged up jet in the carburetor. Take the bottom off of the carburetor and use some carburetor cleaner and spray up into the ports and passages of the carburetor. Also inspect the bolt that holds the carburetor on for any holes in the sides of it and down through the center. If it has holes use a small wire to clean those holes out and then spray the holes out with the carburetor cleaner. Let me know if you need more help.
It ran with the fuel in the spark plug hole and stopped. I have to go get some cleaner.
Is it running correctly now?
