connecting distributor advance to intake

Actually, what you're looking for is the port that has no vacuum at hot (slow) idle, and starts pulling vacuum just above idle. Here are port-identification photos for the Holley 2210 (top) and 2245 (bottom) carbs. This should get you headed in the right direction for connecting all the right hoses to all the right ports. Do not randomly disable or disconnect vacuum pots or other parts. The vacuum pot that's not the choke pull off is an idle speed stabilizer. It works for you, not against you, and makes the car less likely to stall when the A/C is turned on or the (power) steering wheel hits the stop or another transient condition slows down the idle speed. Leave it hooked up correctly.
