Hmmmmm appears. This crap gas that we now get with alcohol causes corrosion and plugs orfaces. Regular use of Seafoam prevents this. Like others have said also check the fuel cap. My tractor was cutting off while cutting the grass. I replaced the fuel filter and it still did it. Left the cap off and I ran great sitting there. Put the cap on and backed it off a turn or two and it ran well cutting last week. See what happens this week.
