QUESTION
In the attached photo you will see that there is a lever attached to the spindle of the carbies.
There is a little spring attached to the side of the block which attaches to the lever.
I haven’t seen this in any photos in any other vehicles and just wonder if it’s a good idea.
The other issue is the pickup point for the vacuum hose for the headlights on the front side of the inlet manifold for cylinder number one.
I’m assuming that if I have that lever in place I will need to find a right angle connection so that the headlamp vacuum hose joins from below?

ANSWER
Unfortunately your attached photo does not show if you have a carburettor backplate
The throttle cable and return spring are usually mounted centrally to the backplate
The spring and cable should be connected to the adjoining linkages between the two carburettors
This prevents the internal throttle spindles from twisting with constant operation
If spindles are twisted then the butterfly valves will not fully close and an erratic idle speed will result
I recommend you reconfigure the current set up so it operates correctly
