Small Engines (Lawn Mowers, etc.): riding mower engine, fuel flow, spark plug

Question
I have a '82 MTD riding mower.  Was mowing and it just sputtered and died.  Engine turns over but doesn't start.  Replaced spark plug, but it still doesn't start.  Any advice would be welcomed.

Answer
Hi Eric,

You will need to determine if the problem is a lack of spark or a lack of fuel flow.  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 while squirting fuel or starting fluid into the carb intake.  If it starts, then the carb most likely has dirt, debris, gummed fuel or water 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.
