Spark plugs
The type of spark plugs to be used is:
- Marelli CW 7 LP
- Bosch W 7 D
- Bosch W7 DC
- Champion N 9 Y
- Lodge H LNY.
Spark plug points gap: 0.6 mm (.020").
The spark plug is best cleaned with petrol and a
wire brush, using a needle for the inner part.
In re-fitting the spark plugs, ensure they are start-
ed by hand for a few turns, completing the opera-
tion with the wrench in the tool kit. If not properly
started, the cylinder head thread may get stripped.
For all events, the plugs have to be replaced every
9000 km (5600 miles) even if they appear to be still
in good condition.
