Before you ask, there is an accessory lever pictured behind the accelerator connection which is not used or original to this model according to every example I can find. It spins freely on the shaft and has no bearing on this discussion.
The first photo shows the accelerator rod removed with the adjusted length adjacent to its mounting location. (see second post)
The second shows the rod installed in its most functional position but would also raise the accelerator pedal to its theoretical maximum height.
Finally shows the pedal return spring setup as found in the car when purchased. I noticed the spring closest to the firewall doesn't match the illustrations in the shop manual but does seem to perform its task.
I would like to see other examples of working setups if anyone has them to share? Thanks in advance!
