I have a BX that recently started running a bit choppy and sputtering after using it for 10-15 minutes. After a bit of poking around, I determined a blockage of some sort exists either in the fuel tank or the line coming off the tank, prior to the first fuel filter. When I disconnected the fuel line before the first filter, the fuel slowly dribbled out. I shot some compressed air up the line, and the fuel poured out as expected. It was good for a while, but then the problem returned. I did the same thing again. Since that was just treating the symptom, it of course occurred again. I've since cut a 2.5" hole in the top of my tank so that I can see and access the side of the tank where the fuel exits. Haven't seen anything obvious, but this weekend I'll drain it again and get in there with a vacuum, now that I have this access port.
BUT, THE QUESTION, which is really more of a mystery, is this. I can operate the tractor for 10-15 minutes just fine, and then it'll start sputtering and die. If I shut it off and come back 30 minutes later, it still sputters. If, however, I come back 24 hours later, it'll go back to running fine for 10-15 minutes before sputtering out again. I can't think of any sort of obstruction that would decide to remove itself overnight and wait until the next day to return. Typically if something is clogged up, short of touching Jesus's robe, I don't expect any miraculous healing here like has been occurring. Can anyone think of something that would clog a fuel line and then miraculously heal itself overnight, repeatedly? This has been happening for a few weeks.
Like I said, I believe the fuel restriction to be in the tank or in the first line coming out, but now I'm wondering if there could be a secondary condition further down the line that reveals itself after the engine reaches full operating temperature.
