Well, cleaning the pilot jet on the 10247 carb certainly helped. But it didn't cure it. Not to mention, if I put the mower away with gas in the tank, I can expect to find that gas on the garage floor later. So, I ordered the .040 pilot jet, needle and seat, float, carb-to-engine gasket, carb-to-intake gasket, and a fuel cut-off valve, I gotta get this mutha squared away. Hopefully this will get it.
