This one I've wondered about for some time;
As an example, the choke pull off linkage or throttle linkage;
at some point they went from one end using a small clip to keep it in place to one that is bent on the ends...
When the throttle linkage changed, it meant that to remove the rod without removing the top plate meant that the plunger actuator roll pin has to be removed.
I have generally seen what I believe to be untouched original 1969 (OEM) carbs with the clip retained linkage, and 1971 (OEM) seemed to use the non-clip version, but 1970 has seemed to baffle me;
Which style did 1970 use?
When did the change over happen?
Thanks for your insight
