Blocked injector

[brenten5]

What's the best way to unblock an injector?

Tractor had been sitting for about 4 years so I assume it had been working 4 years ago so is it best if I just run it and hope it frees itself up?

Injectors dont just block. The fuel pump element might have gotten stuck. Fill it as high as you can with diesel and run it untill its running on all cylinders. Then drain it and top up the oil to the supposed level.

The "injectors" inside the pump were stuck to start with but I have since rebuilt it and re timed them but it's still missing on one cylinder

When you loosen that injector line on a running engine, does it spat fuel ? If so, stop the engine take the injector out and mount it on the fuel line in a manner that it sprays beside the engine, then run the starter with some throttle to see if it sprays a cone of fuel mist. If it drips the nozzle is bad.

Injectors dont block, there is too much pressure behind it, if it blocked it would explode. But its quite common that a worn injector starts dripping instead of spraying.
