Hello. Thank you for choosing Just Answer. My name is***** will be happy to assist you. Di you re-set the gap between your flywheel and ignition module?
Do you have some carburetor cleaner in a can?
No problem. Did you get your flywheel bolt good and tight?
If not, it is possible that your flywheel key is sheared.
Was it sheared? How did you prevent it from turning, as you were tightening your bolt.
I would check again. Backfiring is sometimes an indication of a timing issue. Your flywheel key may have sheared again.
It is shearing because you are not getting your flywheel bolt tight enough. Remove your spark plug, and put some soft rope into your spark plug hole. The rope will serve as a piston stop, to prevent your flywheel from turning, as you tighten your bolt.
It is best to remove your flywheel just to be sure.
If your engine was running prior to you initially removing your flywheel, I believe that once you replace your flywheel key, and properly tighten your bolt, your engine will start up and run.

Awesome! I am glad your flywheel key did not sheer again, and that your engine ran great. I should have asked about the make and model of your mower.
You are correct, the regulator is totally different from the one I posted.
