governer spring on the carb not set? If you unhook the throttle cable can you move it by hand? Maybe the float is stuck?
 
(quoted from post at 03:15:03 05/31/15) got the ferguson 40 started and it is running wide open .any ideas?

If all of the governor linkage is hooked up and there is no binding in any of the linkages then you have a non functioning governor.
 
Something is up with the governor. With the engine off, throttle lever in the idle position, the throttle plate on the carb should be spring loaded slightly toward open and easily moved from open to closed position. If it won't move, it may just be stuck from sitting.

Keep in mind, the governor spring (on the linkage above the governor housing) is trying to pull the throttle open, the spinning balls inside the governor are trying to push the throttle closed. It seeks a balance, the harder the spring pulls, the faster the engine turns, the harder the governor tries to close the throttle,

If it's not stuck, take the governor link off the carb, hold the throttle plate closed, start the engine, see if you can control the speed by hand. If not, there is a problem in the carb.

With the governor linkage still off, holding the throttle at idle, see if the linkage lines up with the hole in throttle plate. If it doesn't line up, adjust the length so it will hold the throttle closed.

It should be trying to push the throttle closed. You can try pushing the governor link to the open position and feel the weights try to push back, the higher the RPM, the harder it should push back. If the governor link doesn't try to push back there is a problem in the governor. The front cover will need to come off to see what's wrong.

Even if it was, it wouldn't have anything to do with your governor problem.
I'm also thinking that even if the governor was completely not functioning, you should at least be able to hold it at idle with the control lever and have at least some control of the RPM. A very slight mis-adjustment will cause a no control condition.
There are very good adjustment instructions over on the FENA site. http://fergusontractors.org/fena/wp-content/uploads/Throttle-Linkage-Adjustment.pdf
It must be done correctly. I've had mine out of adjustment to the point where it would only run at a very high RPM. It's easy to do.
 
I think I see the problem. I think the spring on the carb is too stout .it is holding the butterfly straight up all time. this a carter where can i find a weaker spring?

There are only 2 springs, one is the compensator spring that I think connects up by the thermostat housing, the other is the actual governor spring, it is on the end of the rod coming down to the governor. The compensator spring is there to counterbalance the speed selector so it doesn't move by itself. If there is a spring on the carb linkage, aint supposed to be there!

The governor spring is what sets the engine speed. If it is pulling too hard, the linkage from the speed selector is out of adjustment.

I don't have my manual here, hoping someone will post a picture of the linkage.
