As I said earlier I have run the car without vacuum
It doesn't solve my problem
My modulator adjuster has a black rubber cap with a little T underneath it
And I believe i was adjusting it half turns So about 1.5 really
The amount it's supposed to be is 2.9 the amount each whole turn adjusts it is .4
It was slipping like mad in it's original posaition that's why I was trying different adjustments
