Engine backfire

the engine seems to run fine, but today when we were trying to teach my daughter to slalom, I did get a intermittent backfire when I'd add power. So, she was learning, which means a lot of idle time, but maybe 70%-80% of the time she'd say go, as soon as I started adding power, the engine would backfire, and then run normally. It's just on the intital throttle increase. New plugs and wires last year. Any ideas?

    Water in the fuel filter?

    Intake or exhaust backfire?  If intake, you are running lean.
