My carb has the same 'added plate' (black with round stud on it, pic in post #82) that the throttle cable attaches to, and pretty sure it is stock. The secondaries open via vacuum, not mechanically on that year also, correct? Vacuum on my '88 anyway. I've had issues with getting them to open previously, so was curious. Is your picture before or after you moved it? Thanks.
