Here are the instructions to delete the SCV on a Autolite 1100 & convert the vacuum port to ported vacuum.
You need a #35 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 two 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.
When complete just screw the SCV back into the carburetor to maintain a stock appearance.
