Bx is diesel , so it does not have carburetor, it has injection pump body. You have fuel tank, then fuel filter, then the electric fuel pump,and then the second filter, just before the injection pump. Open the bleeder or remove the hose from the last filter at the injection pump body,and turn the key on to let the electric fuel pump work.
Let it pump until all you get all the air out and only have fuel flowing. The connect the fuel line or close the bleed screw. Then see if the tractor will start.
If tractor does not start, loosen the high pressure fuel pipes at the cylinder head, one for each cylinder, and crank engine until there is fuel squirting. Then tighten the lines and start the tractor.
Are you getting fuel to the injection pump?
The tractor has a stop solenoid, that kills engine, is it stuck in the kill position? That would keep the fule from getting to the injectors? What was the result of the tests? Fuel or no fuel?
OK, I'm retired, and have plenty of time,!
