Here are the instructions to delete the SCV on a Autolite 1100 & convert the vacuum port to ported vacuum.
You need a #36 drill bit to drill a shallow hole to just the depth of the 6-32" brass set screw. You will use 3 of these set screws.
Tap only the orifices circled in red there are three circled.
The last orifice that has to be plugged is the one illustrated with the wire showing the passage to the venturi. Use caution not to drill more than the length of the 6-32 set screw. This eliminates venturi vacuum to the distributor at WOT.
You will have to remove a brass plug so you can drill a new orifice just above the throttle blade. The original port is just a little too low. Plug the old lower orifice with epoxy.
I have the screw in plug so my advice is when you drill the new orifice above the lower port which you blocked use a smaller drill so the signal to the distributor comes in faster.
When complete just screw the SCV back into the carburetor to maintain a stock appearance.
