Jeff, I finally found a few minutes to spend on my truck and still can't see how the throttle cable is supposed to be hooked up. I have the Carter BB1 carb and the choke cable attaches on the inside of the carb, between the carb and the block. The accelerator rod attaches on the outside. My thought of connecting the throttle cable to the linkage/spring assembly on the firewall won't work as it appears it would restrict the accelerator. So at this point I am still in need of some help. Hopefully maybe there is someone that has the same truck/setup that can help with a picture or more information.
