An ignition coil requires external electrical power. A magneto requires only mechanical power to create an ignition spark. If an engine HAS no electrical power (lawnmower, tiller, chain saw) then a coil would not function.

What is the function of magneto coil?
magneto coil is replacement supply voltage for lights and others when bike runs, it also acts as a charger for battery.
The magneto air gap is a precision measurement thats taken between the?
The magneto air gap is a precision measurement that's taken between the edge of the flywheel and the ignition coil armature. The flywheel and the crankshaft are held together in alignment by the flywheel key.

How can you tell if the magneto in a riding lawn mower is bad?
does it have spark to the plug if not the part you might check would be the coil or the electronic start module probably the latter if it is a newer mower or of ots older then the coil magneto usually dont go bad could be a bad gap between the coil and the magneto if its an older mower could be a bad set of points if its an older mower point gap could be bad spark plug could be bad as I don't know exactly what the lawn mower is doing hard to tell what is wrong
Difference between shunt coil and tripping coil?
a shunt coil needs external supply & tripping coil gets supply from itself.
Troubleshoot No firing from armature magneto and spark plug?
air gap improperly set between fly wheel and magneto, bad coil, spark plug harness. Would not hurt to check the spark plug gap and ensure the connector end is tight
How does a magneto power the coil in a scooter?
A magneto is an electrical power generating device which operates without the need for a battery to energize the coils. A magneto uses permanent magnets to induce an electrical current, which is "pulsed" Direct Current [DC]. These pulses are controlled [by "points" in the "old" days] to "time" the pulses to the coil primary winding coil, which the creates the high voltage ignition pulse which is delivered to the spark plug[s].
How do you time the magneto?
place the magnet on the flywheel in front of magneto and place a buisness card between flywheel and magneto and tighten magneto down.......remove buisness card..
Craftsman 4.5 no spark?
You probably need a new coil/magneto. Follow the plug wire to it. If it's a magneto you can try a little sand paper to clean off the flywheel magnet and the magneto points of contact. They aren't touching the magneto so you can get some paper in there. If it's a coil, you will need a new one.
