Yeah: the procedure is fark with it until it works

Pedal stop is usually the last thing you adjust. This is from memory, but start with the short rod closest to the throttle. Adjust the length so that the crank arm under the throttle is about horizontal-ish in the middle of the throttle travel.

Then install the long rod underneath. This has an adjuster in the middle so it can be adjusted in-situ. The bushing in the crank arm across the firewall should be about half an inch to an inch or so off the firewall. You can adjust the length here to set the resting throttle height.

Finally, adjust the throttle stop so that the throttle is full open just as the pedal hits the stop. You don't want too much extra travel in the pedal or that puts strain on the linkage. Depending on where the stop ends up, you may need to do a bit more messing with the adjuster in the long rod if the stop is too high or too low.

Again, this is all from memory, but I think that's pretty much what I did last time.
