Small Engines (Lawn Mowers, etc.): B&S lawn mower no start, briggs stratton, ceramic insulator

Question
Why will the mower not start?  Gas OK, removed spark plug and saw good sparks, Cleaned spark-plug, cleaned air filter, oil is full.  Newer Briggs Stratton 5hp mower with automatic carburator (with primer).  Was running great until I cut some heavy grass and the engine cut out.  

Answer
 Hello Daniel:

 1- Check the Compression. 2- Replace the Spark Plug (not Clean). It could have Cracked the Ceramic insulator and isnt firing under Pressure. 3- Check the Carb. It may have gotten Trash into it. Hope this Helps.

 Good Luck

 Respectfully

 John
