Um....why do you WANT your lawnmower to do this? Backfires are generally not very good for the engine.

The sort answer is this: you cannot make your engine do this without sacrificing performance across the operating range. You'd be better off getting a cap gun and firing it into the air at the times you want your lawnmower to backfire.
