Well, I bent the mulching blade and had to order a new one which I did. Then I put the new blade on and I am backfiring all over the place when I mow the lawn, and the power is not what it used to be. Seems I sheared the fly wheel key. Well not fully sheared which is why it was still running but the timing was off. Going to order a new one from http://www.hhlce.com/shop/Electrical_Parts/Flywheel_Keys.htm Be careful though the one that was OEM was either zinc or aluminum which was nice so I did not bend the crankshaft when I hit that root.
