I put a 1" 4-hole carb spacer on recently, so I should probably tune the carb right? I've been wanting to anyway. Problem is I've never done it before. Is there anything wrong with experimenting?

I think I have an idea on how to do it. Turn the screw clockwise until the engine starts to hesitate, and then turn counter-clockwise about a full turn? I should do this on primary and secondary right?

I guess I should pick up a vacuum gauge too. I want the highest vacuum at idle right?

Turn each screw 1.5 turns (360* turns) out from the seats. Don't force the screws into the seats. Fire up the car, and let it warm up. Turn one screw out until it begins to lower the rpm, and back it up just a tad. Then do the other. Continue doing this until you've got a nice idle. You may have to adjust the curb idle speed.

This will give you the maximum vacuum without using a vacuum gauge. Set the timing/dwell, and then re-do the carb idle if the timing has changed.
