They do go bad. Especially if there is debris under the engine cover that makes it run hotter than it is supposed to.

You have no spark on your old snapper lawn mower and you would like to know what all you to look at to gain spark?
Your mower gets it spark from a coil that is under the engine shroud. There is a magnet on the flywheel that with each revolution causes the coil to spark. Possible problems are: 1) There is too much rust on the coil or flywheel to let the current go between the two. Taking them apart and lightly sanding them until you get a clean metal surface usually takes care of this problem. 2) If it is a riding mower, there is a ground wire that shorts out the coils which stops the mower when the key is turned off. If the ignition switch is bad it should cause a no spark issue. Or, the wire could be pinched somewhere and killing the engine. You can remove the spark plug, unplug the small black wire off of the coil and see if it sparks then. If it does then this is your problem. 3) The coil itself could be bad.
