Stuck Control Plunger (K-Jet. aka CIS FI) 200 1981

The Control Plunger (inside the Fuel Distributor) can become stuck due to gum and varnish from stale gas. Getting it out to clean and lubricate it means:

1) Removing the Airflow unit with FD attached.
2) Separating the FD from the Airflow unit.
3) Holding the FD in both hands and smacking it down on large socket.

The plunger's inertia when the FD's downward travel is stopped will (with luck) eject the plunger into the socket so it can be removed the rest of the way. Be careful not to scratch the plunger's surface in any way.

Maybe this operation and labor is what your mechanic plans to charge for?
