15.7 Air Cleaner
The injection system fitted to this car detects the level of air drawn into the engine, and uses this information to
control the fuel level. It is most important that the airflow is not restricted. The air cleaner should be changed
every 10,000 miles, or more frequently in dusty conditions or regular town use. Your Morgan service agent
should change the air filter element as the procedure involves removal of the RH wing, bonnets and front cowl.
When replacing, use the correct specification of element and make certain that it is fitted correctly on the raised
areas in the cleaner and on its lid. Be sure the lid is properly secured and the air pipe attached. While checking
the air cleaner the pipes connecting it to the engine should be examined. It is most important that air does not
leak into the system, as this will affect the running of the engine. The clips should be checked for tightness and
the pipes for damage. If a pipe is damaged be sure to replace it with one of the correct specification.
15.8 Spark Plugs
The spark plugs should be checked every 10,000 miles for the correct gap. The electrode and body should be
cleaned and examined for damage. If the plug shows any sign of damage or deposits it must be replaced. When
fitting new spark plugs be sure only the correct specification is used and the gap correctly set.
To Remove Plugs
This requires the removal of the intake manifold and must not be attempted by the owner. The fuel system
setting must be checked after this has been done and can only be undertaken with the correct test equipment.
Warning
Under no circumstances should any modification to ignition or fuel system be attempted.
The ignition system fitted to this car needs no adjustment by the owner.
