Removing spark plugs
Installing spark plugs
Unscrew the spark plugs with a suitable
spark plug wrench.
Grasp the spark plug connector and pull
it off. Do not pull the ignition wires as
they may separate from the connectors.
For better access to the spark plugs,
remove the air cleaner. See page 61 on
how to remove and install the air cleaner.
Reconnect all hoses. Interchanging of
hoses affects the operation of the engine.
Therefore, make sure the hoses are
properly reconnected.
When installing the end pieces of the
cleaner duct, be sure the rubber sleeves
between cleaner and end pieces, and the
rubber seal on the carburetors are located
properly.
Insert them by hand and screw them into
the cylinder head as far as they will go.
Only then use the spark plug wrench to
tighten them firmly. Do not overtighten.
Dirty spark plugs should be cleaned with
a sand blaster, but if not available, the
carbon can be removed with a wood or
plastic pick. Do not use a wire brush. The
plugs should also be clean and dry on the
outside to avoid shorting and arcing. The
gap can be set by bending the outside
electrode. The gap should be 0.028 inch.
The correct spark plug gap is 0.028 inch.
Since the spark plug gap tends to increase
in time during normal operation, it is ad-
visable to replace spark plugs every
12,000 miles.
To close the lid, perform the operation in
reverse order.
To open the lid inside the luggage com-
partment, roll the floor covering out of the
way, then turn the lid handles to the OPEN
position and lift up the lid.
You have access to the engine compart-
ment through the rear outside engine
compartment lid and through another lid
located inside the luggage compartment.
Before working on any part of the engine
compartment, turn off the engine and let
it cool down sufficiently. If work has to be
done with the engine running, exercise
extreme caution to prevent neckties, jewel-
ry or long hair from getting caught in the
V-belt.
