Problem with Lawn Mower Engine Running Rough

Judy asks, ?After changing the spark plug in my lawn mower, it ran fine once, then started running rough again. What could be the problem??

There are several solutions to try including adjusting the spark gap, cleaning the air and filters, and switching to ethanol-free gasoline.
