Note: Ensure that the vehicle is in a well ventilated space and away from naked flames or other possible sources of ignition Removal
1 Disconnect the battery terminals.

2 While holding a rag over the joint to prevent fuel from being sprayed out, loosen the control pressure line from the warm-up valve.

The control pressure line is the one connected to the large union of the valve.

3 Mark each fuel line and its port on the distributor. Carefully clean all dirt from around the fuel unions and distributor ports and then disconnect the lines.

4 Unscrew and remove the connection of the pressure control line to the distributor.

5 Remove the locking plug from the CO adjusting screw, then remove the three screws securing the distributor (see illustration).

6 Lift off the distributor, taking care that the metering plunger does not fall out. If the plunger does fall out accidentally, clean it in fuel and then re-insert it with its chamfered end downwards.

Refitting
7 Before refitting the distributor, ensure that the plunger moves up and down freely. If the plunger sticks, the distributor must be renewed.

8 Refit the distributor, using a new sealing ring. After tightening the screws, lock them with paint.

9 Refit the fuel lines and the cap of the CO adjusting screw then tighten the union on the warm-up valve.
