There were quite a few variations of the divorced choke system incorporated in late production of '72 IH vehicles. And the kalifornikate version (both pickalls and Scout II) was it's own "special" version as it incorporated an electrically-heated choke stove that was thermostatically controlled.
If you will post a nice, detailed pic of what your setup is right now, I can help ya either make an "adjustment", a repair, or a workaround. "some" (but not all) of these choke stove systems were adjustable to a degree, some where not.
The divorced choke system was an excellent design actually and incorporated by many oems in response to the much tighter emissions standards beginning in m/y '73 and going forward. At that the "hot air" choke systems were gone for the most part (except on medium duty vehicles), and true "electric" chokes (most with thermostatic control) had not come into vogue yet.
Using an auxiliary heating element incorporated into the choke stove system for the kalifornikate vehicles made the choke open and "pull off" much faster by eliminating the need for the exhaust crossover passage to fully warm as an indicator of proper engine warm-up. And of course...that little detail created it's own drivability issue on the affected vehicles, the dealers soon figgerd out how to bypass that system until it was time to smog the rig again!
