D14 Governor/Carb Springs

I made a mistake on the D14 and now it's vexing me. I took the carb off back in 2009 and at that time, I didn't take photos of everything, I just "knew" I would remember. The D14 governor/carb springs are different than the D10/D12 and my D15 is a Diesel, and doesn't use the same set up. There are two springs rather than the single spring that hooks to the throttle arm for the carb butterfly on the other machines. With the others, the spring clips into a hole in the rod that connects to the carburetor and clips over one of the manifold studs. Not so with the D14, there are two and my memory is that they interact in some manner, like one spring connects to the other and the rod even goes through the larger spring. The parts manual doesn't shed any light on how they connect though clearly, one of them still will connect in a manner similar to the D10/D12, but the larger one doesn't.

If any of you have a D14 or possibly and early D15 gas, could you provide a photo or description of how these connect? It was dumb to ignore photographing something so non-intuitive to a 10 year old memory. What I might end up having to do, is hook it up like the D10/12 and see if it works. But the other spring is much stronger.
 
Any spring, or in your case, springs, on the left side, on the gov-to-carb link, is only there to fight hunting, surging, or erratic governor operation. [Although, if angled, that spring can effect speed slightly.]

The heavy governor spring, over on the right front, controls wide open governed speed. [I put a D15II gov spring on my C to get more speed out of it]

The early tractors had no hole in the link. The little anti surge spring was an after thought. But even when just hooked around the rod, and anchored off to a manifold stud, they can provide some dampening of any surging. I think the only difference from the B,C,CA,D10,D12,D14,D15 is the main gov. spring.

I would just make sure the gov-to-carb link is "indexed" properly, and try it without the anti surge spring first.
 
Okay, that sounds simple enough. This arrangement that was on it, was like using two springs to create a graduated pressure. Now I'm wondering if the second spring was added because of problems with the old governor housing. The parts manual doesn't show two springs (thought sure it did but it may be my shop copy is different since they are different vintage manuals).

For now I'll put the single spring in place like the other G-149s have.

Getting awful close to first start.
