You may have sheared off your flywheel key, that will throw the spark timing off. Have you confirmed that you are getting fuel to the motor? Try using starting fluid, if you can get it to start briefly with starting fluid, your problem is fuel related. I would recommend getting yourself a repair manual, it will have the specs for testing your electrical components. Good luck.

BTW, what year is your Warrior?

Well then, I would check that flywheel key, pop off the inspection covers on the head and check to see if the valves move when you turn the motor over. While you have covers off, check your valve lash, tight valves can make for hard or no starting. Lastly, get that repair manual, it is a must have if you want to work on your own machine. Like I said, it will have the test specs and procedures to test the electrical parts that you can check. Good luck.
