B&M Converter is bad

Then I start on the right side and turn the screw in until it starts to stumble the idle and then I back it off a 1/4 of a turn. Then repeat on left side. Then I repeat the process again just because. Then once that's done I set my idle where I want it.

I did that to start with back before I got a vacuum gauge. I started at 1.5 turns out and did exactly what you said, but the engine would jump all over, and not really want to stay running.

Once I got the vacuum gauge, and started turning them out as described. Watching the vacuum come up from 10 to almost 15. Then readjust my idle. Then adjusted them again until almost 15, readjusted my idle. I did this 3 times total until I no longer got any increase off of the 14-15 at 800rpm. The engine smoothed out big time and no longer jumped and actually just purred.

Although. Im not sure if I was suppose to keep readjusting the screws.
