Customer Question
Good morning. I...

Good morning. I have a John Deere x300 for 3 years now. I am having a reoccuring issue. Not every time but reoccuring none the less. At time, the (both) carbs are not getting gas. The engine will crank forever. Throttle up and chocke on. Sometimes it starts right up and others it just cranks. My only accessment has been no fule reaching carbs. If I pull the fuel line from the fron carb and draw fuel up; reconnect and then fires. Sometime it occurs with low fuel or tank running empty and other times the fuel level does not matter.

Mechanic's Assistant: Do you have fuel in the tank? If so, is the shut-off valve open and the fuel clean?

New fuel. Not a new problem. Have been going on. No shut off valve that I know of or have ever adjusted.

Mechanic's Assistant: Do you plan on doing the work yourself?

Yes dependant on what it is

Mechanic's Assistant: Anything else we should know to help you best?

That is pretty much it. Almost like no fuel is pumping but I do not think these lawn tractors have a fuel pump

X300 does have a fuel pump, A pulse pump, that uses the crankcase pulse, to pump fuel. But look at the fuel tank, Deere uses three different tanks, and on one, the fuel pickup is thrugh the top of tank, with a suction tube. The fuel system up to the fuel pump, has to be vacuum tight, or will not suck fuel. Fuel pickup can be restricted, or the hoses before teh fuel pump can be leaking vacuum. See fuel pump in link below.
