I replaced the sediment bowl fuel filter on my JD 1010W because the old one was leaking around the bowl and the gasket was shot. After letting the tractor sit for a day or two with the petcock totally off I get about a cup of gas pouring out when I remove the air intake tube. I had trouble starting and keeping it running last fall and it seemed to flood easily so I rebuilt the carb over the winter. Is it possible that the gas is draining from the cylinders, or could I have a defective fuel filter? I think I have other issues with the distributor causing it to have a weak spark, but want to get the fuel supply problem figured out first.
