Possible kick down solution!

Hang in there while I try to explain this. I woke up this morning and thought of an idea to modify my current linkage to make it work with my thermo quad. Basically I set the slotted rod on the carburetor at a position that the throttle could fully open when slid all the way back in the slotted rod. I’ll have a spring run from the carburetor rod forward to a an extension of the slotted rod. I’ll have an equal strength spring to use as the return for the kickdown linkage. as the throttle Pulls it will pull on the Forward tight spring allowing the throttle to come back but also pulling the kickdown linkage back. when the kick down linkage hits it’s end point there will still be some space for the throttle to move back against sting tension in the slot.
Yellow spring will be a tight spring that will allow the throttle to move back but also have enough tension to pull the kick down linkage backwards the red spring will be the return spring for the kickdown linkage.
I know it’s confusing and it may not work but once I get it all marked up I’ll take a picture.
