: I've had the choke hang up on my 1945 carbs if
: the air cleaner housing was not correctly
: installed.
: Also check the hoses on the bottom of the air
: cleaner housing for the heated air door.
: Sometimes
: they come out of the little metal tabs that
: hold them in place and then they hang down
: and
: interfere with the choke linkage. Look for any
: mechanical interference that occurs when the
: air
: filter housing is installed. This may be
: difficult to do.
:
: Have you tried a Chrysler dealer for a new
: carb? I checked on one for my 1987 slant 6
: truck
: about 5-7 years ago. (The carb on that one is
: worn out in the throttle body area) They
: wanted $460. OUCH!! I think
: your '86 van will have the ESA (Electronic
: Spark Advance) system and probably a
: electronically
: controlled lock-up torque converter. If so then
: the curb idle ground switch (which is part
: of the
: carburetor)must be hooked up and functioning.
: It provides a signal to the computer that
: controls
: spark advance (cancels advance from speed and
: vacuum when throttle is at idle position)
: and also
: enhances operation of the lock-up torque
: converter.
:
: I have substituted an earlier model carb with
: out the curb idle ground switch and left the
: wires to
: the computer disconnected. It will still run OK
: and most people would never know the
: difference
: in operation of the torque converter and spark
: advance.
:
: I've never been able to find concrete
: information on this but I suspect the
: carburetors for the ESA
: system are specially calibrated too. I have
: found information that hinted toward this.
: Wish I knew
: more on this one.
