Mend Yard Machines 12A-446M729 Lawn Mower Engine Spark Plug

My yard machine wont start? 12A-446M729?

A buddy of mine gave me an old yard machine which needed a new spark plug, oil & gas. It started the last time it was fired up around 12 months ago.

Today I put in a new spark plug, oil & gas but it won't start? When I pull the cable I can hear it trying to turn but nothing happens?

Any suggestions would be appreciated.

Check that there is actually a spark between the two electrodes of the plug when pulling the start cable by removing the plug and holding the side of the plug body to a metal part of the mower using a pair of pliers with rubber covered handles. If you pull the cord and sparks arc bewteen the electrodes then it must be a fuel problem - or you may have 'flooded' the spark plug with fuel by continually trying to start it. When you take the plug out if the plug is wet with fuel dry it off, check for the spark as above and try again. Good luck.
