So I am restoring a set of twin HS2 carbs to replace my single HS4 carb. I am almost done and they are looking amazing but I just noticed that there is no vacuum port to go to my vac advanced distributor. Looking for opinions on my options.
1. use a carb spacer with a port on it
2. I have a vac port with threaded end so I could drill and tap the plug on the manifold
3. I could find the proper vac port and install it on the carb. I found instructions online for location and drill size plus I could confirm the measurements off of a friends carb.
4. do nothing and cap the vac port on my distributor. (not sure if this will cause and issue)
Thanks in advance
