Sears Craftsman II 5.5HP lawn mower: engine doesn't start easy with pullcord. Needs new spark plug? How do I?

How do I change spark plug in this machine? Will such change help easy start with few pulls on the starter cord?

If you have never changed the spark plug on your mower and you've owned it for quite a while that could be the problem.

The spark plug should be located on the front of the engine easily visible to the naked eye so you won't have to search for it. There should be a black rubber wire leading to it and a little rubber plug covering the actual spark plug. Pop off the covering to expose the spark plug( if you have to pull too hard you're tugging at the wrong wire).

Once exposed grab a 13/16 deep 6 point socket, loosen it like you would any other nut, then replace it with a new spark plug and reconnect the wire. Hopefully this works because replacing a spark plug is the least expensive repair to a lawn mower.

You need to drain any old gas out from mower. Fill with new fresh gas. Clean air filter. Set carburetor chock and pull rope. if it doesn't start in a couple of pulls. Then take it to a lawn mower shop. If you have to ask how to change a plug then you are in over your head.
