I have a LARGE lawn and live in the Pacific Northwest where the ample rain
makes the grass grow like mad. I think I last replaced my lawnmower spark
plug 3 years ago. I check it each Spring and clean it up a little. The
mower starts first time, every time.

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?
