Micro-Metering Head
This component is supplied in two parts. To assemble, it is only necessary to push
the two units together as illustrated. For some carburettors with obstructions within
the Venturi, it may be necessary to trim portions of the tapered adaptor unit to gain
the required clearance.
On some carburettors where the shape of the air intake or obstructing projection
interfaces with the carbalancer, a simple adaptor can usually be made up from rubber
hose of similar size.
Adjustment
Adjustment of the reading on the scale is made by holding the outer rim of the head in
one hand and rotating the inner bezzle with the other. Once this adjustment has been
made for the engine, it is only necessary to move the head from one carburettor to
the other, pressing the adaptor firmly into the Venturi and adjusting the throttle stop
screws until the same reading on the scale is given by both or all carburettors.
Easily read scale
The scale is divided to make readings on individual carburettors easy to remember.
In setting the carburettors, the float can be positioned next to convenient mark
or number on the scale by adjusting the inner bezzle on the metering head or the
throttle screw. The scale has a spring clip which is connected to the scale holder by
a universal joint. Both the scale and the holder are tapered and the narrow end of the
scale should be pushed into the wide end of the holder. The tension on the universal
joint is adjusted by the distance that the scale is pushed into the holder. To avoid the
holder losing its springiness, it is advisable that the scale should be removed before
storage.
The clip should be fixed to any convenient projection under the bonnet within easy
reach of both carburettors and the scale should then be adjusted on the universal
joint until it is reasonably vertical. The carburettors may then be balanced in the
manner described in the general instructions.

• Can be used to fit most
carburettors (side draught and
down draught with air intakes
(venuri).
• Suitable for from 1" (25.4mm) to
2 1/4" (57.15mm) diameter.
• Suitable for use on SU Solex, Auto-lite (Fomoco) Stromberg,
