Doug and Paul,
A couple of pictures to show the flat ground needle ( a little better) and
the Front 'Velocity Stack' holder, which will be bolted to the front plate.
All mating surfaces to be O- ringed (Viton).

You will notice I haven't cut the needle material down to size yet, but I
have made the flat guide. The needle will be welded to the guide and will
fit into a slot, cut into the slide - the guide stops the needle from
turning and gives a flat top for the threaded adjusting rod to push on.

There will be a spring under the flat guide to maintain the needle height.
Needless to say the spring will be compressed as the needle is adjusted down
or carby is leaned. This makes a two piece (needle with adjuster) set-up.

I may have to make a two piece slide to accommodate this system, but I am
still working on the best way to accommodate the needle and slide.

Hope these ideas help with your development Doug, then again you may have a
totally different approach.
