Nice pics Tommy. That governor has captive flyweights. The only pics of one of these I have seen had ballbearings, but the same principal applies.
Meporsche: In the pic that Tommy posted, with that side plate cover removed, that round rod running across the opening(with the 3 screws on it) is the fuel rack. behind that are the plunger springs, and the discs tommy is refering to. would guess that if one of them is out of place, it probably binds the fuel rack travel, so none of the pump pistons gets to deliver fuel?
With that side cover off, you will be able to see if they are all the same, and check for proper rack movement. The rack moves forward to increase fuel delivered, and toward the rear of the tractor to decrease fuel delivered. With the engine NOT running, the shutdown lever all the way forward, and a little bit of throttle applied, the throttle spring(in the rear of the governor) should be pushing the rack all the way forward to the full throttle position. It stays there untill the engine starts, and the RPM increases to the point that the spinning flyweights in the governor start to overpower the throttle spring and pull the rack off of full throttle. Pulling the shutdown lever toward the rear should also pull the rack toward the rear of the tractor just like the governor weights would if the engine was running. I do not know how far the rack should be able to travel, but if it is starting at it's full throttle position, I would think it should start to move to the rear shortly after you start to move the shutdown lever to the rear. If you pull the shutdown lever all the way to the rear and it dosn't move, or only moves toward the end of the shutdown travel, then the rack is stuck at low throttle and not delivering enough fuel to fire the engine.
It looks as if you will have to remove the hand plunger/feed pump assembly to gain access to this cover plate. I would definitely want to talk to the dealer before I started disassembling a pump on a tractor that is under warranty...
