I have a Sears Craftsman lawnmower that won't start anymore. I'm not
sure how old it is (it was a hand-me-down from my father) but it's at
least several years old. Had to get a new blade last year. Within
the past 3 years I've drained (by turning it on it's side) and
replaced the oil a couple of times. I use 10W-30 or 10W-40 car oil.
After I replaced the oil a few weeks ago, the mower started to have
more difficulty running. It sounded and felt like it was struggling
with less and less power. Finally it got to the point where it was
very weak. Now it will not start . (It is self-propelled and has a
pull-cord to start it.)
Is this related to oil? Could some oil have leaked into a wrong
place? Is there something else that should be opened for
How can I tell if the spark plug is too old and needs to be replaced?
How long does a lawnmower usually last?
