For my outdoor gas tools (snow-blower, chainsaw, lawnmower etc.) , I run the engine out of gas when I turn them off, instead of using the "Off" control.

I only use these tools occasionally, so I thought it would be better to run the carb dry to avoid gas staying in and clunking up the carb.

The effect is, obviously, when the gas runs out of the carb, the engine gasps a little before it turns off.

Is there any downside to this procedure?
