Has this engine ever run properly with the current CIS system? I ask to see if something has malfunctioned or if it never functioned properly in the first place.

I suspect that the entirety of the system is all from 73.5. The injector lines are metal, the WUR is 001, etc.
I can test the throttle switch in the morning, but I think I've done this before. *If* its working, what else can be done (other than replacing the system)? Can the system be fattened up with a different adjustment? Like I said above, Im fat while idle (~13), stoic on cruise (~14.5), and lean on WOT (~15.5).
Clearly the engine needs a real solution, just wonder if theres a temporary bandaid to toss on it in the meantime. Thoughts?
