Will the black knob part of the linkage move freely in the long slot? Because if its tight, and will not slide in the long hole, it wrong,

Is fuel supply open? - The top of level to the left or right?
The first picture shows the solenoid fully pulled in, it can not move any more to the right, however, it can more to the left when not powered, but it is stopped by the lever

Yes the knob moves freely in the slot.
What I figured out when the solenoid is not powered it has spring and it should push the top of the lever all the way to left until it hits the hard stop nut. but the lever stops half way. Since the knob is not tight, the only way the lever can move to the right something in the engine governor moves it to the right.

Is the spring broken, or missing in the rubber "prophylactic" on the piston? Have you made sure the piston slides in and out of the solenoid housing smoothly?

The spring on the solenoid is in working order, I checked at all ready.
I found this https://www.steelsoldiers.com/threads/mep-803a-governor-question.223729/ this could be it since I found one of the gaskets for the metering pumps in the bottom of the unit, but I could not find which one it belong to and they did not appeared they were touched.

You can find lots of interesting things in the bottom of a generator set. They may have been from 20 years ago, or last week. The only way to know is to look.

Sorry to join late to the party, but I see a couple things that seem odd.
You have already discovered that your fuel lever is not moving correctly and it also sounds like the solenoid is not working correctly either, you should have way more than 1/2" of travel in it.
Also, Your fuel stop lever looks a bit abnormal... kind of home made actually.
It looks as if it was made from a piece of aluminum flat bar and I wonder if the bottom part that is supposed to hit against the lower screw ( at full fuel ) is not quite shaped right, It appears the screw is hitting on that weird corner and the top is supposed to touch against the upper screw when the solenoid is deenergized, ( fuel off ) and that isn't happening either, BUT the real issue here looks to me like your fuel rack is stuck.
