On most lawn mowers the coil and the fly wheel are located under the recoil housing or engine shroud.
Probably a rusty flywheel and coil contacts. Take cover off and sand them.
If you are talking about a small engine such as a lawn mower, the air gap between the coil and the flywheel is usually is .015 to .020 of an inch. A piece of cardboard from a cereal box can be used as a gauge if you don't have the proper gauges.
Lt133 lawn tractor will not fire is coil bad
generally the alternator sits under the flywheel
It is a magneto, a little piece under the flywheel cowl with two metal tabs that almost touch the side of the flywheel. Embedded in the flywheel is a magnet that provides a signal to the magneto each time it comes around to fire the spark plug.
On most lawn mowers there is no timing - they have the flywheel set, as long as the shear pin is in place, it will put the magnet by the coil at the proper time to fire. The points are run by the gap (you set the gap on the points) and the pin pushes the points open at the proper to fire. The only setting you have to do is the gap on the flywheel to the coil and the gap on the points.
The coil is under the cowling on top of the motor where the flywheel is.

To test a lawn mower coil, you can use a multimeter to check the resistance between the coil's terminals. If the resistance falls within the manufacturer's specified range, the coil is likely functioning properly.
you can go to any parts store and buy a feeler gauge for a couple of dollars. use that to set the air gap between the coil and the flywheel. use the oem specs

Symptoms of a bad ignition coil on a lawn mower include difficulty starting the engine, engine misfiring or stalling, and poor performance or loss of power while mowing.
