Guys i just bought this 1995 craftsman mower that is in mint shape. It has a 15.5 kohler and hydro drive. It runs great until about 1/2hr into mowing it slowly starts to act like its running out of fuel. Mine has the rear mounted fuel tank with the mechanical fuel pump. I thought it was the pump so i replaced it along with the fuel filter. That made no change, so i drained the tank and cleaned that. No change. It has good spark even when its hot. I was ruling out the coil cause it doesn't just shut off, but slowly starts to spit and sputter. It will idle just fine. Do you guys have any other ideas before i replace the coil? It still seems fuel related.:frown:
