Why does my Craftsman 917.273220 engine backfire when turning it off?

If your Craftsman Lawn Mower engine backfires when turning it off, ensure that the engine throttle control is set to the “SLOW” position for 30 seconds before stopping the engine. Move the throttle control to “SLOW” position and allow it to idle for 30 seconds before stopping the engine.
