My dad was a muscle car guy, so this happens all the time, I say things no one understands constantly, like calling cams Bump sticks. and so forth.

Alright, so we have some AFM anamolies... Could it be? Another rare part? Missing idle adjuster, missing....sensor.... Take a gander and tell me if this is normal or should I be worried...
Yeah, I sorta cleaned it, but then I thought, "well maybe I'll have to buy a new one, considering it looks different from 100% of all of the other AFMs I've seen on this site." and stopped cleaning it.

Nothing major then, and thus, not the source (or future cause) of the woes of our 280?

why do you have the valve cover off? do you have a haynes manual or the how to rebuild your datsun OHC motor? you really shouldnt **** around with the timing chain without absolutley knowing for damn sure no doubt about it you know what your doing.

well shucks guys, no more idle problem, no more RPM surge, but there's just a hint of hesitation (throttle lag) my dad doesn't think is normal, any ideas for this one? As far as I'm concerned it feels fine, but he's the guy that knows so whatever.

The AFM is good, as long as whoever told me it was normal for some models to be missing a sensor and idle screw was correct. The carbon track was still cherry and contacting, the flapper's motion is smooth and easy, and now it's clean, the harness port was almost flawless, you can't see it too well in the pics, but I was surprised.
What about the hesitation? He insists it shouldn't be like that at all.

The word "tuning" literally means "tuning." You TUNE the AFM to run BETTER than stock. The carbon track is not the only adjustment. You should read the entire page about tuning the AFM.
Hesitation could be one or more of many things... TIMING (which you have or haven't set yet???), plugs, wires, cap, rotor, old gas, placebo effect, etc. Your dad, as an ASE tech should know these things...
