Question
QUESTION: Hello,
Turned my mower at an angle to clean the underside.  The following day went to start it and am having difficulty getting it to run.   Made sure there was enough gas, checked the oil, checked the spark plug, pushed the primer button 3X and the mower will turn over but shuts down right away. Have tried priming it numerous times and it will kick over but quits right away.
I now realize I shouldn't have tipped it to degrass it but not sure what to do now?
Thanks in advance for some help.
Margaret
