Small Engines (Lawn Mowers, etc.): cant get engine started, fuel flow, spark plug

Question
i have bought a new MTD pro mower 21" with Honda 5.5HP engine, just can get it started  

Answer
Hi Mike,

If the mower is brand new I would take it back.  Otherwise, you will need to determine if the problem is a lack of spark or a lack of fuel flow.  Right after it quits, remove the spark plug, reconnect the wire and lay it against the engine head.  Pull the engine over and watch for spark at the plug's electrode.

If good, then try to start it while squirting fuel or starting fluid into the carb intake.  If it starts and you can keep it running by adding fuel, then the carb most likely has dirt, debris or gummed fuel inside.
You will need to remove the carb, disassemble it, clean all the small internal openings and blow it out with compressed air.   Probe each and every hole with a small wire.   A carb rebuild kit wouldn't hurt either.  

Let me know how you make out.
Michael
