Anyone ever have this problem?? Darnedest thing: I was mowing along edge of sidewalk, came up to the corner, went past the corner, rear tire dropped off the sidewalk (about a 3" drop) and almost instantly the engine started stuttering, like it was starved for fuel. I tried choking it, ran for maybe 15 seconds, then died. I figure I must've had a fuel line come off, but no sign of that. Maybe the jolt loosened something in the fuel tank? Is there an automatic fuel line shutoff for accidents like on the old Ford F-150 pickups? Nah. Any ideas? I'm not looking forward to taking it apart yet again. Been a lot of that already this year. Thanks in advance for any suggestions. Happy mowing!
