avs air fuel adjustment screw

That's an oldie but goodie right there. You adjust it just like any of the rest. Here's how. First, you need to make sure the timing is right. Then...for automatics.....apply the parking brake and block the drive wheels. Drop it in drive. Make your adjustments from the SIDE of the car just in case it decides to overcome your safety precautions. Don't wanna see a flattened member. Attach a vacuum gauge to a MANIFOLD vacuum outlet. Adjust the air screw until you acheive the highest vacuum reading and then one half additional turn lean (counter clockwise). then you're done.
