I was mowing and I ran out of fuel, and I asked my father if there was any more fuel; he said yes there is plenty. I grabbed full gas can and put the fuel into the lawn mower and started it. It ran for about four minutes and died. My father failed to tell me that he just put diesel into the gas container that I used. I already flushed the fuel tank with gasaline and replaced the fuel filter. It still won’t run. I know the problem is fixable I just don’t what else to do. Please help if you can.
