Tractor won't fire

So I have a craftsman riding lawn mower that I changed the ignition switch, coil (changed 3), new spark plug, and new starter and my lawn mower still won't fire. What should I do next?

If it was built after 1986, the only ignition component that generates a spark is the ignition module/coil. There is a small kill wire coming off the coil along with the plug wire. Disconnect that small wire and see if you get a spark. This is assuming one cylinder and one coil with the air gap on the coil/flywheel at .010.

If you can't get a spark the coil is likely bad. If you get a spark and the engine running, you'll have to choke it to kill the engine.

** If you're using those "Dozen for a Dollar coils from Ebay" the three you put on may have been bad. And the starter has nothing to do with it firing if it spins over.

What was the symptom that prompted you to change the first thing listed above? A chronological history is very helpful when trying to eliminate possibilities
