Miss America with throttle control

IDK about the spring thingy but it shows in the pic it goes in the other hole ,, i guess you will find out LOL Engine looks good !

Mechanically speaking I deduce the following:
Surely the throttle ring function works crossover for the following reason.
If it is connected as indicated by the line and the red arrows, when the engine warms up, the force of the spring and the force of the draft control may cause the seeger ring to expand and not tighten the speed regulator ring. The distance between A and B becomes larger, therefore it is possible that they do not move together, that is, the seeger (C) ring moves differently from the speed (D) control ring.
While if you connect it crossed, indicated by green lines and arrows, the distance between A and B is maintained, and it even tends to tighten the throttle control ring, which guarantees that even when there is temperature, the seeger ring and the ring of speed control, they will always move together, in unison, guaranteeing the correct throttle setting desired by the pilot. My humble opinion.

I think the spring throttle was kinda rare on Miss America and most came without it.

that looks right now that i see it better , you see were the string has been ... is the spring thing hooked to the airplane ? I had one of those engine may still have it LOL and have a couple fuses of the plane but no wings if i rem. right . Happy T-Day to you too
