Hi Dave
The unit senses air flow by means of the manifold vacuum, the cable going to
the metering unit is an over fuel (choke) control for cold starting.
If you would like to view a schematic of the metering unit have a look here

The diagram is missing a few details, so if anyone wants to see the full
picture I could scan it and mail it.

How does the unit sense air flow?  And I thought there was only a throttle
cable going to the metering unit?  I'm afraid I'm not all too familiar with
the PI system.
