My lawnmower won't start again.
It is a four stroke Honda, the fuel supply is OK, the spark looks OK
when I take the plug out and rest it against the cylinder head and
pull the cord.
However, I know from experience, that as soon as I go down and buy a
new spark plug, the mower will work again. The plug seems to need
renewal, even though I have a small lawn, and it would have done no
more than 10 hours work, maximum.

What life do others get out of their plugs? Could I be missing
something?

I have been down that road a bunch and the only thing that was told to me by
a small engine repair fellow on this was : A small engine will flood out or
get the spark plugs soaked in gas and or oil for a while and it does
something to the white part , I guess ceramic stuff and it will not hold
back the electricity and just not make it fire at the points. The gas will
kill the insulating propertys and make it not fire right. So just change the
plug every year and live long and prosper.
