Answer
Safety switch is causing the problem.  Did you check the neutral/clutch, seat and deck/blade engagement safety switches.  You mentioned you had one coil.  Dis-connect the small wire connected to the coil and re-check for spark.  If you have spark the coil is fine and you know there is a safety switch grounding/shorting your ingition coil to ground.

Let me know what you find.
