Okay, so last time I mowed the lawn, I was starting to have trouble w/ my mower. It was backfiring on me when I engaged the mower, but the engine wouldn't shut down. It would backfire and then continue on. Well, this time, every time I engage the mower, the engine quits on me! Please help, I've looked through the manual and I can't find anything on it. Also I have checked to make sure everything is connected and there is nothing around the blades. Thank you so much to whoever gets back to me.:dunno:
