There should be a little adjustment screw that sets how closed the plate
can get. If it's not adjusted to give a bit of clearance the butterfly can
stick shut and no spring can pull that open. Also check how smooth the bushings
are, if they are gummed up it can stick also.

Re: 87 wrangler starting problem - HELP!
The choke should be almost all the way closed when the Jeep is off.
Once you start it, vacuum hits the choke pull off and opens the choke
about 1/4" so it gets some air to run rich for cold starting.
Then as the engine warms up or as long as the choke has power to it, the
choke will open all the way in less than 5 minutes. It will stay open.
If it is not opening, then the electrical connection on the choke is
suspect for a dirty connection. There should be 12 volts there as long
as you have oil pressure. If you do not have 12 volts there, then go to
the oil pressure sender near the back passenger side of the block and
see if the plug is plugged in. The oil pressure sender has a switch
that allows power to pass when running. The power goes to the choke and
a relay dead center of the firewall in the harness that supplies power
to the manifold heater under the carb.
If you do have 12 volts at the choke and it still isn't working, it can
be seized up where the shaft comes out of the electric coil unit. That
is common or the sucker is dead.
Manual kits come with a bracket you can hang below the dash edge.
Good luck,
Mike

Yes, I've vague recollection of using feeler gauges to check the gap but I
haven't a clue to what the measurement would be.
I'd be willing to bet that Bill knows....

Re: 87 wrangler starting problem - HELP!
On the BBD all that is done by bending the V section of the linkages.
Hopefully the OP has all the BBD settings and how to set them.... The
Haynes CJ manual is the best for his engine and underhood wiring.
