Hi, there are many things that could prevent your mower from starting. Here are some common ones.

A highly likely cause of the mower not starting is a bad spark plug. Spark plugs usually only cost a few bucks, so it's not a big investment to try a new one and see if that gets your mower to start.

If that doesn't help, you may want to try changing the oil and replacing the air filter. If it still won't start, the carburetor may have a blockage, or you could have a more serious problem. Try spraying some starting fluid into the carburetor (with the air filter removed and the mower off) then put the filter back on and try starting the mower -- if it starts then dies, there is probably a blockage in the carb.

If nothing else has worked, attach a spark plug tester to your spark plug to see if the plug is getting electricity. If it's not, there's a problem somewhere with one of the electrical components.
