Well who ever posted delete everything seems to have taken that down. Good! Okay Tony you seem to be confused about your vacuum routing because you nk longer have the original carbureator. This is no big deal, your original carb and the current carb,both have manifold vacuum ports,and at least 1 ported vacuum port. So what was connect to ported on the original connect to ported on what you have,same with manifold vacuum. You should have ported vacuum to a thermo vacuum switch to keep egr inoperable until engine is warm and a tvs for captured spark vacuum,and efe. If you're missing the B.S. for the vacuum advance take your pick run it on ported or manifold vacuum whichever works best for you,originally it used both,you get one or the other until you find the missing pieces.
