for some readjustment of the Needle-Valve.
Remember that, as a safety measure, it is
advisable to increase the Needle-Valve
opening by an extra half-turn
counterclockwise, prior to establishing a
new setting. The same applies if the
silencer type is changed.
A different silencer may alter the exhaust
pressure applied to the fuel feed and call for
a revised Needle-Valve setting. The use of a
different glow plug may also require
compensating carburetor readjustments.
The correct functioning of the carburetor
depends on its small fuel orifices remaining
clear. The minute particles of foreign matter
that are present in any fuel can easily partially
obstruct these orifices and upset mixture
strength so that engine performance
becomes erratic and unreliable.
O.S. Super-Filters (large and small) are
available, as optional extras, to deal with
this problem.
One of these filters, fitted to the outlet tube
inside your refueling container, will prevent the
entry of foreign material into the fuel tank.
It is also recommended that a good in-line
filter be installed between the tank and
needle valve.
Do not forget to clean the filters regularly to
remove dirt and lint that accumulate on the
filter screen. Also, clean the carburetor itself
occasionally.
