Small Engines (Lawn Mowers, etc.): Craftsman DYT 4000, proper manuals, water in the fuel

Question
Hi Nathan, I have a 2004 craftsman DYT 4000 and currently it is making a popping or backfiring noise. The RPM's are also oscillating and sometimes sounds like its going to die. I have cleaned out the carb two times and after I did that each time it ran perfect. After using it for an hour or two it starts having the same symptoms and continues to get worse. I replaced the fuel filter and cleaned the air filters. The oil is also fresh and the plugs look great in color. I also turned the key and held the fuel hose in a can pumping out about two cups of fuel. It was clean and I did not see any trash or water in the fuel. Do you have any ideas as to what the problem might be?
Thank you for your help


Answer
Hello Jordan:

I am Not Nathan, However if you Seen me the Model Numbers Off the Mower, Please. I can Locate the Proper Manuals and Better Assist you. Does the Carburetor have a Fuel Shut Off Solenoid? Is this an OHV Engine? The Model Numbers will Help Answer a Lot of Questions I have About the Equipment. They are the XXX.XXXXXX Numbers Usually Located Under the Seat on the Frame. Thanks.
