Customer Question

Hey Jack. I just bought an stx38 with a 13hp Kohler and my problem is that when I engage my mower I lose lots of power almost to the point of stalling. It will stall trying to cut grass. The seller said it was just serviced. What could be the problem?

Engine may not be getting enough fuel through the carburetor. Was fuel filter replaced? This is gravity flow fuel system. so filter and fuel line and fuel shutoff valve all have to be open fully.
