Nevermind. I find the Fuel easier to adjust if I just pull the whole FDC off the pump anyway so I should have a perfect view of the droop screw while I have the cover off again...
It was a medical day today, so I was unavailable until just now.
Just as a note for your bonnet, the test for a servicable FDC (when it is still plumbed) is to remove it from the IP, but hang it from its hoses, and then turn on the accessory switch. That will fire up the pump in the tank, and put the FDC under normal operating pressure. Then, while holding the FDC in its normal upright position, watch for drips of fuel forming around its piston shaft. A drip every minute or two wouldn't be a problem, a drip every second, would. Unfortunately, the FDC isn't rebuildable in the traditional sense, you would have to replace the shaft, or rebush the hole in the FDC's casting that it passes through, to eliminate excessive leaking.
The screw for the droop/drop adjustment screw is just a setscrew with a lock nut and washer to hold the adjustment. It could be either a hex key, or a slot... I'm thinking hex key, but I can't remember for sure.
