A common mistake.

Obtaining highest vacuum first with one screw has the engine idling on near correct A/F ratio, then you end up not knowing where you are.

Far better off starting at 1-1.5 turns out and knowing where all the screws are while targeting highest manifold vacuum.
It is as much an art as a science.

Now, back to the original thread please.
