Small Engines (Lawn Mowers, etc.): Lawn mower dies out, fuel flow, fuel line

Question
I have a Murray 5.0 self propelled lawnmower given to me that dies out after about 10 minutes of use. It will restart if I let it sit a second or two but eventually dies out completely. It seems it may be a fuel line problem. Where do I start? How do I drain the fuel I just put into it?

Answer
Hi Joy,

Drain the fuel using a siphon hose or a piece of gas line.

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 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.
