It has good spark, turns over, but won’t stay started. It is brand new…used maybe 4 or 5 times.

Just a couple of things to check, may or may not work:

  • Does it have gas?
  • There is typically a switch on the lawn mowers that cuts off gas supply to the engine. Has it been turned to ‘Off’ position by someone?

The only thing I know to ask is if you used 100% pure gasoline. New gas types that have ethanol can cause the issue you are talking about.
