GENERAL UPKEEP— Lubrication
Dry off with a smooth rag or good quality brush, taking care not to let any fluff or hairs
remain, and leave for a quarter of an hour whilst the remaining film evaporates before
replacing the sump.
In the meantime, brush with fuel the gauze intake filter. Do not forget to refill with clean
oil when the sump is replaced.
Caution
Do not attempt to clean out the sump with paraffin or petrol unless it is removed
from the engine, as any remaining liquid will tend to dilute the oil.
Ignition Distributor

Every 5,000 miles (8,000 km.), the cam should be smeared lightly with engine oil.
A pronounced squeak occurs when the cam is quite dry. Withdraw the moulded
rotor arm from the top of the spindle (care should be taken because this part is made
of a brittle material) but do not remove the screw exposed to view. Apply, by means
of oil-can, a few drops of thin machine oil around the edge of the screw and down
the hole in the centre, to lubricate the cam bearings and distributor spindle
respectively. At the same time, place a single drop of clean engine oil on the contact
breaker arm pivot.
When replacing the rotor arm make sure that it is pushed on as far as possible.
The moving parts of the automatic advance mechanism should be lubricated with
winter grade engine oil. This can be squirted through the gap between the cam and
