Small Engines (Lawn Mowers, etc.): riding mower cranks but will not start

Question
QUESTION: I BOUGHT A MTD YARD MACHINE 2009 MODEL IN SHOW ROOM CONDITION. THE PERSON I BOUGHT IT FROM SENT IT OUT TO OVERHAUL CARBURATOR. I TRIED TO START IT BUT IT WILL NOT START. I CHECKED THE FUEL SOLENOID, AND ITS WORKING. THE VALVES ARE SET CORRECTLY. I AM NOT GETTING SPARK FROM THE COIL, BUT THE COIL CHECKS OUT GOOD, STILL NO FIRE. THE FLYWHEEL SHEER KEY IS GOOD. WHAT ELSE CAN I CHECK? BRIGGS AND STRATTON ENGINE MODEL 21BS07  TYPE 0453 B2  CODE 0903112A THIS ENGINE IS ON A MTD YARD MACHINE 638RL    MODEL 13AC762FO52  1645828   IF YOU HAVE ANY IDEA   FOR ME TO TRY PLEASE LET ME KNOW THANK YOU FOR YOUR TIME IT IS GREATLY APPRECIATED.    FRED

ANSWER: How do you know the coil is good?  No spark is an indication of a bad coil.

I would dis-connect the small wire from the coil and see if you have spark.  

Let me know how you checked the coil to verify it is good.

QUESTION: I CHECKED THE COIL LIKE YOU SAID THIS MORNING AND I HAVE SPARK. TRIED TO START ENGINE AGAIN, BUT WILL NOT START. WHAT IS THE NEXT STEP? THANKS AGAIN FOR YOUR HELP. FRED

Answer
If you have spark with the small wire dis-connected from the coil the coil is good.

You could have a bad spark plug.  Did you replace it?

Is the fuel bad?  Have you tried priming the engine with known, good gas?  I use an old style diner ketchup bottle with a tapered tip for priming.

Let me know if the engine starts by priming.
