That about normal for just winging the throttle. I thought he had it on a dyno.

I don’t think the engine is under any sort of load. Here’s another carb about a day later. It too was for a Pontiac https://youtube.com/shorts/Ugl6HN0t3A8?si=HOU7m8e1-4aUKyKO

Plugged POE

 That carb does not have the POE, (pull over enrichment), what you have circled in your picture is the secondary air bleed tube.
 If it had the POE system, there would be a 3rd set of tubes located in the slightly larger holes just ahead of the air bleed tubes, and these would be longer and thicker. In addition, the discharge holes for the POE are located just above or below the choke blade when it's closed.
 If those are not there, the carb never had a POE system. If there are discharge ports, then it's possible that someone pulled the tubes at some point and didn't replace them.

Sorry.  New to the quadrajet terminology.  From reading about a plugged secondary air bleed tube it said this condition would result in rich idle conditions.  This can't be true since my carb runs extremely lean.

Secondary air bleed tube would have no effect on idle, but it would definitely affect WOT secondary metering.

[Ponchonutty]

So this is a late 80’s Chevy style carb body with the top of mine after installing the missing secondary cam. Once the o2 sensor warms up, you can see she’s now twice as rich as it once was. So, rebuild number 3 on the way.  DO NOT SEND A CARB TO EDEN, NC!
