adjusting the air flow metering plate height-HOW TO?

Can anyone walk me through making the adjustment on the air flow metering plate height in my 79 930 Euro fuel head?

The plate seems to be riding too high in the cone and needs to be dropped down a few millimeters.

Where is the pin and leaf spring that controls rest position on this CIS air meter for the turbos.....and how do I make the adjustment?

Car has been exhibiting strange behavior for awhile and I started tearing into the CIS system with a fine tooth comb to make sure nothing is out of whack and noticed the air flow metering plate is out of spec.

What type of running anomolies would this cause if the plate was running too high in the cone at rest position?

Thanks,
Fred
