While adjusting the slack, make sure the linkage arm on the carb (the thing the cable acts on) is at-rest and fully seated to its base-idle position (i.e., no fast-idle engaged for the choke or A/C).

Don't pull the housing fully taut; leave a little bit of slack, just enough so the cable at-rest has no tension at all in any circumstance, so the base-idle speed will be determined solely by the idle stop screw, not by cable tension.
Sounds like I got it pretty bang on (idle and deccelaration is clean), made sure I didn't tighten it to max and at least and checked and gave decent enough clearance for both pedal and cable; gave a few hairs of clearance for another few clicks of adjustment on the bar itself in case of later needed adjustment, but overall it felt much better after giving it a good test drive. Will keep my eyes peeled of course.

By chance, I bet you could extend this little bracket if you really needed to gain a bit more tightness in a way huh. Alas thankfully I didn't need it on this occasion.
