Hi All,
Thanks for the post. I will save this in case I ever need to replace, but I might have gotten lucky. I'm a 240 newbie who just bought a very nice '73 original that had been sitting for 22 years in a garage. Of the many things that needed replacing, the choke cable was stuck. It would move with pliers and generally not in bad shape with the original expanding rubber gaskets still in good shape/ My mechanic didn't offer much except to replace it. Zcarsource has a rebuild program for 150, but after some poking around the net, I decided to try PJ1 cable lube. The cable was out of the car so I could let gravity help. Squirted PJ1 in the loop-end and within a couple minutes it was sliding by hand.
