Check
1.
Start the engine and warm to normal operating
temperature.
2.
Remove the air intake manifold 19.70.01.
3.
Ensure that the cold start lever on the metering unit
is back against its stop and that there is clearance
between the cam and adjusting screw on the manifold
linkage.
4.
**
Hold a Crypton synchro check meter against number
six intake and open the butterflies by turning the
throttle adjusting screw clockwise sufficiently for a
reading to register on the meter scale (eg 3).**
5.
With the engine revolutions maintained compare the
readings from number three and one intakes with that
of number six.
6.
If the readings are all the same no adjustment is
required and the throttle adjusting screw should be
reset and locked so that it just touches the
countershaft operating lever.
