Will start after 5 seconds blows white smoke for about 3 minutes fouls plug and dies. Have replaced carb and head gasket same problem.
 
Just an observation.

This is another post where the OP replaced everything possible with new parts. Mower still won't run.

Back to regular programming. Check for vacuum leaks.

White smoke is water. Do you have water in the carb? Does the mower sit outside in these fall temps? Getting cooler at night depending on where you live. Any rain going on? Gas cap good?

Fouling plugs is excessive fuel. Check carb float height, air filter and carb needle. Is the fuel tank clean?
