Thanks for every bodies input.

Silly me put a 4mm allen key into a screw that had been cranked up. Then assumed something was wrong.

After looking at a generic CIS document I got to thinking there is no way an adjustment screw designed like that could possibly have it's adjustment thread firmly fixed to the upper housing of the meter.

So I took that 4mm SHCS all the way out.... low and behold. A 3mm allen key engages at the bottom of the vacant hole, and floats with the metering plate. Very tough to adjust, but a result never the less. Waiting on an AFR monitor before I do too much else

Am I correct in thinking that this hole will leak vacuum if I was to run the engine with this 4mm "plug" screw removed, giving false readings?

Everybody's input is valued here. Thanks again. I will no doubt have more questions in the next few weeks.
