Worked as expected
When I need a part for anything practically, i know where to go: eReplacementParts. Rarely do they not have what I’m looking for. Do yourself a favor and start here first! The spark plug was an obscure one to me, so I bought it here. It went right into the motor and fired up as expected!

Hello Julia, Thank you for your inquiry. We would recommend checking the spark plug, fuel filter, air filter and fuel tank vent. We have included a link to our video on testing the spark plug: https://www.youtube.com/watch?v=_vShfKez9vo and check the fuel lines and filter for any clogs or debris. Good luck with your repair.
