I bought the generic chrome handle cable from NAPA. I lubricated the solid steel cable/wire prior to installation using chassis grease. It works buttery smooth now, versus the sticky old one.
So I think that's the secret. Thread it through the dash to where you want it, cut the housing to length. Then coat the inner wire with grease and thread it in, adjust to carb as needed. My carb just had a lever with a hole in the end, so I had to bend my choke wire into a zig-zag to accommodate it.
