Question: Does it make sense to tune the engine, at least the idle setting, without the linkage connected. Then make the adjustment to the linkage that connect it to the carb linkage ball. If I connect my linkage now the way it is set, the linkage will hold the throttle plate off the stop, not good. Logic tells me to adjust the carb to run properly, then adjust the linkage to properly connect to the carburetor "ball".
What does the linkage in front of the carburetor do? It has some association with the alternator. Is it a governor of some type?
