Flooding. Too much fuel coming in.
Carb float valve stuck, carb float out of adjustment...
What's the history of the engine? New to you? Did it ever run good for you?
After the fuel line is attached and it stalls out, pull the plugs and see if they're wet with fuel.
Engine serial number may help us with BOMs.
