I did some research on how to adjust the 2150 carburetor on my 1984 Bronco II using a vacuum gauge. Every where I read, they said 18-20in of vacuum is normal for a healthy V6...
I was able to pull 24-25in stable on the gauge while idling at a normal RPM.... is this ok??
I would like to add that the curb idle screw is ALL THE WAY backed out and it’s idling just fine.. normal.
I know that In general you should aim for the highest possible vacuum pressure but 24-25 seems over and above what anyone else is getting. I installed a T in one of the vacuum lines coming off the manifold tree for my vacuum gauge.
My bronco has 150,000mi and is in very good shape, probably driven lightly for most of its life. I’m planning on just leaving it this way.. unless this high of vacuum pressure is a bad thing.
