Hi Dave & Bobbie,
You have run into a problem which is pretty common on BJ8s. The only
force which pulls the choke off in the original system is a rather
convoluted combination from both the high speed idle push rod return
springs and the jet return springs. The net result is adequate to return
the choke to the beginning of where the high speed idle action starts
but once that force is removed the jet return springs alone, acting
through a considerable mechanical disadvantage are really struggling to
do the job.
If everything in the system is in excellent condition, all the way from
the knob to the choke arms on the carburetors it will work, but just.
Ensuring that the inner and outer cables are perfectly free of kinks,
and surface rust and are lightly lubricated helps a lot. Polishing the
inner cables with very fine paper is a good idea.
I believe that in bad cases the factory used to install a pair of return
springs which pulled down on the trunnions fitted to the carburetor end
of the secondary choke cables as I have seen several cars which had
exactly the same combination of parts to do this that appeared to have
been installed for a very long time.

Subject: BJ8 choke cable
Hi all,
I was putting the choke cable back through the firewall, and have a
question about the block the cables are attached to. The cable coming
from the dash slides into the center of the block and the cable stop,
then the screw is tightened to hold it. Fine. The two cables to the
carbs are slid through the block from the rear, then through the bracket
and the sleeves, on out to the carbs. What holds the cable ends in the
block? When the choke is pulled, all works fine. When the cable is
pushed in, the block slides forward, but the cables don't move, they
come out of the block. The PO must have had this happening, because
there is a sheet metal thingy bent over the back of the block and held
on by the center cable stop screw. This is not in any photos or
illustrations, so it can't be right. Should the choke/carb springs be
strong enough to pull the cables back and I need to loosen and lube
something there? or is it something else I'm not seeing?
Thanks in advance
Dave & Bobbie
