Choke driving me crazy!

When I put a 73 dual plane intake and 2 brl on my 67 273... same 73 model choke, everything except... I purchased the thickest carb base gasket I could find to put under that 2 brl. , reduce fuel percolation. That is what changed the chokes throw. At one point I thought I might have to fab a spacer to lift the choke from the well 1/8 inch. As I continued with adjustments, creative rod bending and such, I noticed the little vacuum choke pull wasn't fully retracting. It worked to create the primary gap no problem ( set via horse shoe bend in its link ) but without a slight finger assistance it stopped short of its full travel. Replacing that cured it. A slight vacuum leak in it or just worn out? I don't know.
Now I can actually kick the choke out before the engine/choke is fully warmed which is something I hadn't been able to do when this intake and carb was on the 318 in our 73 Valiant.
