Six packs are a labor of love and have quite a large learning curve. I have tried to glean as much information as possible through books and articles and internet. Really it's a somewhat limited source specially in tuning .
Leave that disconnected. with the advance - if you shut it off, the weights should return to “o”. Very light springs will make it idle high but it should still shut off if the throttle closes.
This statement is absolutely correct but I think it just held the RPMs up at a high enough level that it began to slightly engage the outboard circuits all I could make out of it.
