Why does my lawn mower backfire and not start?

Why does my lawn mower backfire and not start?

Troy bilt, MTD, Yard Machines, Toro, Bolens, Craftsman, Honda lawnmowers shouldn’t backfire when you’re trying to start them. This often is a sign that the mower is damaged in some way; for example, you might have run over a large rock or other obstruction. When a flywheel is broken, your mower might stutter or backfire when you try to start it, but it won’t completely engage.
