Help with Carb
Here is a picture of the front drivers side corner of my quadrajet. Am I correct in stating that this is the port that the vacuum advance for the distributor connects to. Also can someone tell me why this port appears to be blocked and should I try to unblock it. Thanks

any unused ports need to be sealed or "capped" to prevent vacuum leaks.
if pollution controls have been removed from your engine it would explain why you have some unused vacuum ports.
originally vacuum hose should have run from distributor to front passenger side port of carb. theoretically you can use any port for distributor vacuum. i use the rear port on my 79, the one next ot the brake booster.
