ADJUSTMENTS.
The engine should not require any major adjustments for at least 20,000 miles.
After this distance, should there be any falling off in efficiency,
it
may be advisable
to have the cylinder head removed for decarbonising, valve grinding and tappet
adjustment.
The correct tappet clearance
is
.012" when the valve is closed.
(Hot
or cold).
Sparking
Plugs.
Sparking plugs should be removed and cleaned in a special plug cleaning machine.
After cleaning, the points should be checked and reset if necessary to the correct
gap of .035".
The carburetters should be checked and cleaned. (See carburetter
section Page
19).
