Recently my CCC 3240 would backfire when I shut it down, ( I do throttle down before I turn it off); anyway I was mowing the other day for several hours and all of a sudden it just quit, I believe I heard a pop when that happened. I can't get it started, could I have a bent engine valve ? cannot see anything wrong, no oil, or crack in the engine block.
