Is this rack moved forward and rearward by the stop cable, or by the throttle cable?
The rack is moved by the governor.
If the rack dosnt move freely, don’t force it.
You didn’t say if you could move the rack, I assume you cant.
First thing to do
Get the engine in a position where any one of the free plungers is in the UP position (spring compressed)
Then try and get the stuck one in to the down position.
Try tapping it down somehow, be careful not to damage any thing.
If you can get a pair of pliers around the spring, then tap the pliers down
You could try tapping a screwdriver between the spring coils at the top of the spring, not the bottom
If you get it down, turn the engine over and it will jam in the up position again.
Keep repeating the process until in goes up and down freely.
Once it moves up and down freely, the rack will be free
Make sure the injector lines are cracked so the engine dosnt start.
As I said in a previous post, Don’t start the engine until you have cheeked that the stop works
