it took me 2 rounds of manual brake bleed and 2 more rounds of power pump bleeder to get all the air out of the brake lines. With the old style tin cup master cylinder.
Test drove it and no pull or soft pedal.
I’m sure you have checked it. But make sure the tube on the base of the carb was solid and not with any movement. I found a vacuum leak there. And what I did I laid some RTV around where the tube come out of the base. Sealed it up and made vacuum gauge go up a few points.
Oh never mind I...
