vacuum/carb/newb question

[vfx3dartist]

Hey All - I decided to swap the old air filter and original setup for a basic edelbrock chrome air cleaner, but I’m not 100% on the vacuum hookup. Does the vacuum advance line go to the open spot on the carb? I tried this and it seems to run fine, but was fast at idle. Do I need to dial it back after the swap? Pic below.

Dizzy needs to hook to a port that does not have vacume at idle but when the throttle start to open. There has been much discussion on this but with this setup you can run the most initial advance and have the best idle.

yep, the advance needs what they call ported vacuum, so a source above the throttle plate needs to be used

i hope this helps but i pointed out my vacum line from the dist to the front of the carb and mine works fine so i hope it helps and the tube on the side of mine is capped off
