avec les meilleures intentions
It looks like DeLoreanGirl's shift point cable is on the wrong side of the throttle shaft pivot. This cable must be pulled toward the rear of the car as the throttle cable is pulled toward the front. If both cables are on the same side of the throttle shaft pivot, the shift cable will just get slacker as the throttle cable pulls toward the front of the car.
Carburetor Troubles... Car is Completely Useless
The trans shift cable is definitely on the same side of the throttle plate pivot shaft as the throttle cable.
DeloreanGirl needs to post another direct side shot photo so we can see if that carb bellcrank even has a lower attach point to connect the cable too.
Given how loose the throttle and trans cable are.
I would move the throttle cable clevis to where the trans cable is attached.
The trans cable needs to be checked at the transmission to see if it is even connected to the Governor. It is way too slack given its extended attachment location.
