I am having what I think is a fuel issue. Maybe someone else had this problem. My mower starts and works for about 10 to 15 minutes then just stops. Now the carburetor was recently changed. Fuel is good in the tank. I am wondering maybe a fuel pump issue?
Tom For model number 33r877-0002-G1 - November 12, 2023

Hello Tom, Thank you for your inquiry. It could be an issue with the fuel pump or fuel filter but we would also recommend checking the magneto and spark plug as well. You can view more in our article here: https://www.ereplacementparts.com/repair-center/lawn-equipment/engine/runs-for-a-while-then-dies/ Good luck with your repair.

Remove the old magneto and replaced it with the new one. When you set the magneto gap between it and the flywheel magnets the gap should be 0.010 The part does include an informational paper with it. You can actually use it as the gap gauge.

The hardest part was moving the fuel tank out of the way to get to the coil. After that, it was easy. I put everything back together and set the gap between the flywheel magnets and coil at 0.010, the engine started right up! Yay!
