To back up a little bit, I am by no means a JD expert, not even a little bit. I understand that least some of the 2 cylinders had an oil pressure operated valve in the sediment bowl assembly. If so then the engine would need to run to let fuel flow. The tractor starts on what is in the carb until oil pressure builds up. It was a safety valve type setup to save the engine when it ran out of fuel. At least that's how it was described to me.</div><div class="ydp223ca359yahoo-style-wrap" style="font-family: Helvetica Neue,Helvetica,Arial,sans-serif; font-size: 13px;" dir="ltr" data-setdir="false">David</div><div class="ydp223ca359yahoo-style-wrap" style="font-family: Helvetica Neue,Helvetica,Arial,sans-serif; font-size: 13px;">

The brass screen inside the gas inlet is clear and clean. the needle and seat are new, and the float is mobile. 3) The line is free and clear; in addition to being brand new, I blew it out with my breath, and it was not obstructed. 4) I took the filter casting off and disassembled it, removing the valve core and the screen. I used air to verify that all passages were free. Summary, there *should* be an open passage all the way from the tank to the drain cock, but gas only flows if I loosen the seal at the sediment bowl. <br></div><div dir="ltr"><br></div><div dir="ltr">I think I have answered all the questions, but I sure seem to be missing something. . . .<br></div><div dir="ltr"><br></div><div dir="ltr">'49 A:<br></div><div dir="ltr">Got both wheels off today and took a trip into town to the tire shop.
