3 Disconnect the coolant hoses from the carburettor throttle valve plate block.

Provided the cooling system is cold and not under pressure there should be almost no loss of coolant. Tie the hoses up as high as possible with a piece of wire.

4 Disconnect the vacuum and vent hoses from the carburettor.

5 Disconnect the throttle and choke controls from the carburettor.

6 Unscrew the mounting flange nuts and lift the carburettor from the intake manifold (photo).
