I bought a new push mower this spring and it has worked wonderfully since I bought it. Yesterday I was mowing the the lawn and it just stopped. I had just started mowing, I had made 5 passes or so and the thing just stopped. It has plenty of gas, new oil, nothing is tied up on the blades, spark plug wire is secure. I try pulling it to restart it and nothing. I don't get what went wrong. One thing I did notice though, is that the air filter was soaked in gas and when I took it out, part of the rubber ripped. THe air filter will need to be replaced. But even trying to start it with the air filter off, still nothing.
