'My Temco R46 is undergoing an extensive annual, and I'm having
trouble reconnecting the Stromberg after getting it back from a
rebuild. My airplane has cables for throttle and mixture control,and
none of the bell cranks, rods and whistles mentioned in the manuals.
Is that correct for the late Fairchild's, too have cables only, or has
someone substituted cables for bell cranks?
The difficulty I'm having is the cable shaft for the throttle cable is
solid material the last 8" or so. And it will
not make a smooth 90 degree turn to the carb throttle arm. Am I
missing some parts? I must be missing parts! a Bellcrank or
something. This setup can't be right. Anyone!

Im probably not the best authority on this, but I too have an R46 and
have replaced the throttle cable with a modern (standard) push-pull
cable.

I believe all the civilian post-war F24s used cables. The military
UC-61s (and early 24s) used rod linkages.

I am not clear on your cable routing. On mine, the end of the cable
housing is clamped to the horizontal member of the engine mount so that
it is perpendicular to the carb throttle arm at mid-travel. That makes
it roughly vertical. The cable takes a 90+ degree turn above the
engine mount and is then clamped to the engine mount as it travels aft
to the firewall. The end of the push-pull cable above the solid rod
has an 8 degree swivel that accommodates the change in cable angle
required as the throttle arm moves through its travel. The original
clamp was composed of two welded pinch clamps, one that fit around the
engine mount tubing and a smaller one that clamped the flexible cable
housing. I cut off the smaller clamp and replaced it with standard
slot mount that modern push-pull cables use.

Perhaps the rigid section of your cable is too long? Mine is a
standard cable with 3 3/8" travel.

Is any of that clear?
