Servo controller and Diaphragm

I've looked at a lot of engine compartments on this site (before the upgrade) and noticed a lot of people yanked the servo controller and servo diaphragm and plugged the holes on the balance tube.

How's the drivability afterwards? My car is up on stands and waiting on some other work before I can fire it up, so I thought i'd get some opinions here in the meantime.

I pulled all the other smog stuff(air pump gear). The hoses were in pretty rough shape and I wasn't about to spend good $ on replacements! No smog checks for my 72 here in TX.

I still have the servo parts, just I'd need to get a vacuum tap with a 1/8" NPT base now since I already tapped the hole for my NPT plug :stupid:
